[0003] [Patent Document 1] Patent No. 6299831 Summary of the Invention [Problem to be solved by the invention]

[0004] Although the '151 patent discloses that the equipment regulates the apparent power inside the facility, it does not disclose regulating the apparent power in the power distribution lines when the heat pump system is regulating the temperature and / or humidity. The present disclosure aims to provide for the heat pump system to regulate apparent power in the power lines of an electrical grid when the heat pump system is regulating temperature and / or humidity. [Means for solving the problem]

[0005] The information processing system of the present disclosure includes an acquisition means for acquiring system information related to a heat pump system used for adjusting apparent power in electric wires of a power distribution system and capable of adjusting temperature and / or humidity, and a capacity calculation means for calculating an index related to the capacity of adjusting apparent power in the electric wires when the heat pump system adjusts temperature and / or humidity based on the system information. In this case, when the heat pump system adjusts temperature and / or humidity, it is possible to realize the adjustment of apparent power in the electric wires of the power distribution system by the heat pump system. Here, the information processing system may further include a margin calculation means for calculating an index relating to a margin of the adjustment capability when the heat pump system adjusts the apparent power in the electric line. In this case, the adjustment content of the apparent power in the electric line of the power distribution system by the heat pump system can be changed based on the margin index calculated by the margin calculation means. The information processing system may further include an output unit that outputs information about the heat pump system when the margin index satisfies a condition set for the margin. In this case, it is possible to suppress output of information about the heat pump system for which a margin index that is not suitable for changing the adjustment of the heat pump system is calculated, compared to a case in which information about the heat pump system is output regardless of whether the margin index satisfies the condition. The condition may be determined based on a lifespan of the heat pump system. In this case, the adjustment of the apparent power in the electric wire by the heat pump system can be changed based on the lifespan of the heat pump system. The conditions may be determined based on the use of the heat pump system for adjusting temperature and / or humidity. In this case, the adjustment of the apparent power in the electric line by the heat pump system can be changed based on the use of the heat pump system for adjusting temperature and / or humidity. The information processing system may further include an output unit for outputting information on the index that satisfies a condition defined for the adjustment of the apparent power. In this case, it is possible to suppress output of information on an index that is not suitable for the adjustment of the apparent power in the electric wire, compared to a case where information on an index is output regardless of whether the index satisfies the condition. The condition may be an index calculated for the heat pump system that receives power through the electric wire that is the target of the apparent power adjustment. In this case, it is possible to suppress output of information on an index for a heat pump system that does not receive power through the electric wire that is the target of the adjustment, compared to a case in which information on an index is output regardless of whether the index satisfies the condition. The condition may be determined with respect to the ability to adjust the apparent power. In this case, it is possible to prevent information about an index that is not suitable for the ability to adjust the apparent power in the electric wire from being output, compared to a case where information about an index is output regardless of whether the index satisfies the condition. The condition may be determined based on a relationship between the capacity and a degree of adjustment required for the apparent power in the electric wire. In this case, it is possible to prevent information about an index that is not suitable for the relationship between the capacity and the degree of adjustment required for the apparent power from being output, compared to a case where information about an index is output regardless of whether the index satisfies the condition. The heat pump system may also be provided with a conversion unit that converts received power and supplies the converted power to a load used for adjusting temperature and / or humidity, and an adjustment unit that adjusts apparent power in a power receiving path of the conversion unit, both of which are capable of adjusting the apparent power in the electric wire, and the capacity calculation means may calculate an index relating to the capacity of the conversion unit to adjust the apparent power in the electric wire, and an index relating to the capacity of the adjustment unit to adjust the apparent power in the electric wire. In this case, when the heat pump system adjusts the temperature and / or humidity, adjustment by the conversion unit and the adjustment unit of the apparent power in the electric wire of the power distribution system can be realized. The capacity calculation means may calculate a first index for a predetermined capacity for the adjustment unit, and calculate a second index for the conversion unit that is lower than that of the adjustment unit. In this case, it is possible to suppress the influence on the temperature and / or humidity adjustment function of the heat pump system compared to the case where a higher capacity index is calculated for the conversion unit than for the adjustment unit. The system information may also include target information about a target whose temperature and / or humidity is to be adjusted by the heat pump system. In this case, the capacity calculation means can calculate an index suitable for the target whose temperature and / or humidity is to be adjusted by the heat pump system, compared to a case in which the capacity calculation means calculates an index without using the target information. From another viewpoint, the heat pump system of the present disclosure is a heat pump system used for adjusting apparent power in electric wires of a power distribution system and capable of adjusting temperature and / or humidity, comprising: an acquisition means for acquiring system information on the heat pump system; and a calculation means for calculating, based on the system information, an index on the ability of the heat pump system to adjust the apparent power in the electric wires when the heat pump system adjusts the temperature and / or humidity. In this case, when the heat pump system adjusts the temperature and / or humidity, the heat pump system can adjust the apparent power in the electric wires of the power distribution system.

[0007] Hereinafter, an embodiment will be described with reference to the accompanying drawings. FIG. 1 is a diagram showing an example of a power control system 1 according to the present embodiment. A power control system 1, which is an example of an information processing system, is a system that controls apparent power. The power control system 1 includes a power grid 10, a plurality of power consuming facilities 20, a calculation server 30, and an instruction server 40.

[0008] The power system 10 is a system provided with facilities for supplying power to power consumers. The power system 10 includes a power plant 11, a transmission line 12, a supply-side substation 13, a supply-side distribution line 14, an automatic voltage regulator (SVR: Step Voltage Regulator) 15, a receiving-side substation 16, a receiving-side distribution line 17, a pole transformer 18, and a consumer-side distribution line 19.

[0009] The power plant 11 is a facility that generates electricity. Examples of the power plant 11 include a thermal power plant, a hydroelectric power plant, a nuclear power plant, a solar power plant, a wind power plant, and a geothermal power plant. The power transmission line 12 is a line through which current that constitutes the power generated by the power plant 11 flows. The power transmission line 12 is installed from the power plant 11 to a supply-side substation 13.

[0010] The supply-side substation 13 is a facility that converts voltage. The supply-side substation 13 is provided on the power supply side of the power-receiving substation 16. In this embodiment, the facility located closest to the power supply side is the power plant 11. Also, the facility located closest to the power receiving side is the power consuming facility 20. Supply-side substation 13 converts the voltage supplied through transmission line 12. Examples of supply-side substation 13 include a substation that converts a voltage of 500,000 V to 154,000 V, a substation that converts a voltage of 154,000 V to 66,000 V, and a substation that converts a voltage of 66,000 V to 22,000 V.

[0011] Supply-side distribution line 14 is a line through which a current flows when a converted voltage is applied to supply-side substation 13. Supply-side distribution line 14 is provided from supply-side substation 13 to receiving-side substation 16. Supply-side distribution line 14 is provided on the power supply side of receiving-side distribution line 17. The SVR 15 adjusts the voltage supplied to the supply-side distribution line 14. More specifically, the SVR 15 detects the voltage supplied to the supply-side distribution line 14. If the detected voltage is not within a predetermined range, the SVR 15 adjusts the voltage so that the voltage falls within the predetermined range. The receiving-side substation 16 is a facility that converts the voltage supplied through the supply-side distribution line 14. An example of the receiving-side substation 16 is a substation that converts the supplied voltage to 6600V.

[0012] The receiving-side distribution line 17 is a line through which a current flows when a converted voltage is applied to the receiving-side substation 16. The receiving-side distribution line 17 is provided from the receiving-side substation 16 to a pole transformer 18. In this embodiment, when the supplying-side distribution line 14 and the receiving-side distribution line 17 are described without any particular distinction, they may be simply referred to as "electric lines". Pole transformer 18 is a facility that converts the voltage supplied through receiving-side distribution line 17. Examples of pole transformer 18 include a transformer that converts a voltage of 6600V to 200V, a transformer that converts a voltage of 6600V to 100V, and the like.

[0013] The consumer-side distribution line 19 is a line through which a current flows when the voltage converted by the pole transformer 18 is applied. A plurality of consumer-side distribution lines 19 are provided in the power system 10. More specifically, a consumer-side distribution line 19 is provided for each power consumption facility 20. Each consumer-side distribution line 19 is provided from the pole transformer 18 to the power consumption facility 20. As described above, the power system 10 is a system that is provided outside the power consumption facility 20 and is a system for distributing generated power to power consumers. Therefore, the power system 10 can also be regarded as a power distribution system.

[0014] Further, the power system 10 is provided with a plurality of electric wire sensors 10S. The electric wire sensors 10S are connected to the supply-side distribution line 14. More specifically, the electric wire sensors 10S are connected to a portion of the supply-side distribution line 14 that is closer to the power supply side than the SVR 15. Further, the electric wire sensors 10S are each connected to each of the receiving-side distribution lines 17 provided in the power system 10. In other words, the electric wire sensors 10S are provided for each of the supply-side distribution line 14 and the receiving-side distribution line 17.

[0015] The electric wire sensor 10S detects parameters related to apparent power in the connected electric wire. The parameters related to apparent power are parameters that affect the apparent power. Examples of the parameters related to apparent power include apparent power, reactive power, reactive voltage, harmonic voltage, current, power factor, and the amount of apparent power and reactive power in a predetermined period. The current as a parameter related to apparent power includes harmonic current. Furthermore, the harmonic voltage and harmonic current may be harmonic voltage and harmonic current of a specific order. An example of the specific order is the fifth order harmonic. Furthermore, examples of the parameters related to apparent power include total harmonic distortion (THD) of current and THD of voltage. Here, the THD of current is calculated from the following formula (1). Furthermore, the THD of voltage is calculated from the following formula (2). TIFF0007617368000001.tif33154

[0016] In the above formula (1), I1 is the fundamental current. n is the nth harmonic current. In the above formula (2), V1 is the fundamental wave voltage. n is the nth harmonic voltage. The electric wire sensor 10S detects the above-mentioned parameters related to apparent power, for example, at predetermined time intervals. The predetermined time may be any time, for example, 60 seconds. Then, when the electric wire sensor 10S detects the parameters related to apparent power, it transmits information indicating the detected parameters to the instruction server 40 together with electric wire identification information for identifying the electric wire to be detected.

[0017] In the illustrated example, one supply-side substation 13 is shown in the power system 10, but the number of supply-side substations 13 is not limited to one. The power system 10 may be provided with two or more supply-side substations 13 that convert the same or different voltages. In addition, in the illustrated example, one receiving substation 16 is shown in the power system 10, but the number of receiving substations 16 is not limited to one shown in the figure. The power system 10 may be provided with two or more receiving substations 16 that convert the same or different voltages. Furthermore, the number of supply-side distribution lines 14 and receiving-side distribution lines 17 is not limited to the example shown in the figure. The power system 10 may be provided with more supply-side distribution lines 14 and receiving-side distribution lines 17 than those shown in the figure. In this case, the electric wire sensor 10S may be provided for each supply-side distribution line 14, or the electric wire sensor 10S may be provided for each receiving-side distribution line 17.

[0018] The power consumption facilities 20 are facilities that receive and consume the power supplied from the power plant 11 through the consumer-side distribution line 19. Each power consumption facility 20 is provided with a heat pump system (HPS) 21, a load device 22, a set value sensor 23, and an environmental sensor 24.

[0019] The HPS 21 adjusts temperature and humidity using power received from the power system 10. Targets adjusted by the HPS 21 include the temperature and humidity of the space within the power consuming facility 20. Targets adjusted by the HPS 21 include the temperature of liquid provided in the power consuming facility 20. In this embodiment, each HPS 21 is provided with a power conversion device 211 and an active filter (AF: Active Filter) 212.

[0020] The power conversion device 211, which is an example of a conversion unit, has an inverter (not shown) and a converter (not shown). The power conversion device 211 converts the received power into power having a specific voltage and a specific frequency using the inverter and converter. The specific voltage and specific frequency are the voltage and frequency required for the operation of a motor (not shown) provided in the HPS 21. The power conversion device 211 supplies the converted power to the motor to control the operation of the motor. This control allows the HPS 21 to adjust the temperature and humidity.

[0021] The AF 212, which is an example of an adjustment unit, improves the power factor and reduces harmonics in a path through which power received by the power conversion device 211 in the HPS 21 passes by supplying a current to this path. Hereinafter, the path through which power received by the power conversion device 211 in the HPS 21 passes may be referred to as a power receiving path.

[0022] In addition, in this embodiment, both the power converter 211 and the AF 212 supply current to the power system 10. The power converter 211 and the AF 212 control the operation of the HPS 21, and supply current to the electric wires in the power system 10 to adjust the above-mentioned parameters related to the apparent power in the electric wires. In other words, the power converter 211 and the AF 212 in this embodiment adjust the apparent power in the electric wires of the power distribution system.

[0023] An example of a method for adjusting parameters related to apparent power in an electric wire by the HPS 21 will be described. When harmonic current is generated in the electric wire, the power conversion device 211 and the AF 212 of the HPS 21 supply a current of a phase that cancels the harmonic current to the electric wire, thereby reducing the harmonic current in the electric wire. Another example of a method for adjusting parameters related to apparent power in an electric wire by the HPS 21 will be described. When reactive power is generated in the electric wire, the power conversion device 211 and the AF 212 of the HPS 21 supply a current to the electric wire, thereby reducing the reactive power in the electric wire. In this manner, in this embodiment, the HPS 21 is used to adjust parameters related to apparent power in the electric wires of the electric power system 10. Here, the apparent power also changes as the parameters related to apparent power change. Therefore, the adjustment of the above parameters related to apparent power can be broadly understood as adjustment of apparent power. Hereinafter, the parameters related to apparent power that are the subject of adjustment may be collectively referred to as "apparent power."

[0024] Examples of the HPS 21 include systems that adjust temperature and humidity. More specifically, examples of the HPS 21 include devices used in HVAC (Heating Ventilation and Air Conditioning) systems, such as air conditioners, showcases that adjust the internal temperature, refrigerators, freezers, water heaters, etc. In the following, the HPS 21 will be described as an air conditioner. When the HPS 21 receives an instruction to adjust the apparent power in the electric wire of the electric power system 10 from the calculation server 30, the HPS 21 adjusts the apparent power in the electric wire in accordance with the received instruction.

[0025] The load device 22 receives and consumes the electric power supplied from the power plant 11 via the consumer-side distribution line 19 . The set value sensor 23 detects a set value in the HPS 21. Examples of the set value in the HPS 21 include a value set in the HPS 21 as a target temperature of the space in the power consuming facility 20 in which the HPS 21 is installed, a value set in the HPS 21 as a target humidity of the space in the power consuming facility 20 in which the HPS 21 is installed, and the like. The environmental sensor 24 detects the weather, temperature, and humidity in the area in which the HPS 21 is located.

[0026] The set value sensor 23 and the environment sensor 24 detect the above-mentioned target information at predetermined time intervals. The predetermined time may be any time, but is, for example, three hours. When the set value sensor 23 and the environment sensor 24 detect the target information, they transmit the detection value information indicating the detection value to the calculation server 30 together with HPS identification information identifying the HPS 21 that is the detection target and time information indicating the date and time when the target information was detected. Here, the detection value information is regarded as system information related to the HPS 21. If the HPS 21 is not operating at the detection time of the set value sensor 23, no detection value information is generated in the set value sensor 23. In this case, the set value sensor 23 transmits the HPS identification information and time information but does not transmit the detection value information. Also, two or more set value sensors 23 may be provided for each HPS 21, and each set value sensor 23 may detect a different type of set value. Also, two or more environment sensors 24 may be provided for each HPS 21, and each environment sensor 24 may detect a different type of information.

[0027] In addition, in the illustrated example, one power consuming facility 20 is provided for each customer-side distribution line 19, but this is not limited to the example. A plurality of power consuming facilities 20 may be provided for each customer-side distribution line 19. Furthermore, the number of HPSs 21 and the number of load devices 22 provided in the power consuming facility 20 are not limited to the illustrated example. The power consuming facility 20 may be provided with more HPSs 21 and load devices 22 than the number illustrated. Furthermore, there may be a power consuming facility 20 that is not provided with an HPS 21 or a load device 22.

[0028] The calculation server 30 is a server device that calculates the current value, the current value per unit time, or the current value in a predetermined time that the HPS 21 can supply to adjust the apparent power in the electric wire of the power system 10. When the current value, the current value per unit time, and the current value in a predetermined time are described without any particular distinction, they may be collectively referred to simply as "current value". When the current value required to improve the apparent power in the electric wire of the power system 10 is large, the larger the current value that the HPS 21 can supply to the electric wire, the greater the contribution of the HPS 21 to the improvement of the apparent power in the electric wire. Therefore, the calculation server 30 calculates the current value that the HPS 21 can supply to adjust the apparent power in the electric wire, using the detection value information transmitted from the set value sensor 23 and the environment sensor 24. The current value that the HPS 21 can supply to adjust the apparent power in the electric wire of the power system 10 is hereinafter referred to as the adjustable amount.

[0029] The calculation server 30 transmits the possible amount information indicating the calculated adjustable amount to the instruction server 40 together with HPS identification information for identifying the target HPS 21 and time information indicating the target date and time. The calculation server 30 also receives an instruction to adjust the apparent power in the electric wire of the electric power system 10 by the HPS 21 from the instruction server 40. The calculation server 30 instructs the HPS 21 indicated in the instruction to adjust the apparent power in the electric wire of the electric power system 10 according to the received instruction.

[0030] The instruction server 40 is a server device that controls the apparent power in the electric wires of the power system 10. When the instruction server 40 acquires information on the detection value transmitted from the electric wire sensor 10S, the instruction server 40 identifies an electric wire that needs to have its apparent power adjusted from the acquired information. The instruction server 40 also acquires possible amount information from the calculation server 30. Then, the instruction server 40 transmits an instruction to the HPS 21 regarding the adjustment of the apparent power in the electric wire to the calculation server 30 using the acquired possible amount information.

[0031] The instruction server 40 and the calculation server 30 are realized, for example, by a computer. The instruction server 40 and the calculation server 30 may be configured by a single computer, or may be realized by distributed processing using multiple computers. The instruction server 40 and the calculation server 30 may also be realized on virtual hardware provided by cloud computing. In the following, when the instruction server 40 and the calculation server 30 are described without any particular distinction, they may be simply referred to as "servers."

[0032] In this embodiment, the calculation server 30, each power consuming facility 20, and the instruction server 40 are connected via a network (not shown). The instruction server 40 and each power wire sensor 10S are connected via a network (not shown). These networks may be capable of transmitting and receiving data. The communication lines used for transmitting and receiving data may be wired or wireless, or may be power line communication (PLC). The configuration may also be such that the communication destination is connected via multiple networks or communication lines.

[0033] Furthermore, the number of calculation servers 30 is not limited to the illustrated example. Two or more calculation servers 30 may be provided in the power control system 1. Furthermore, the calculation server 30 may be provided for each power consuming facility 20, for example.

[0034] FIG. 2 is a diagram showing the hardware configuration of the calculation server 30 and the instruction server 40. As shown in FIG. The server is provided with a CPU 31, a ROM (Read Only Memory) 32, and a RAM (Random Access Memory) 33.

The server is also provided with a communication device 34 (communication I / F) that communicates with the outside. In addition, the server is provided with input devices such as a keyboard and a mouse used for inputting information, and a display device such as a liquid crystal display.

[0035] The ROM 32 and the storage device 35 store programs executed by the CPU 31. The CPU 31 reads out the programs stored in the ROM 32 or the storage device 35, and executes the programs using the RAM 33 as a working area. The CPU 31 executes programs stored in the ROM 32 and the storage device 35 to realize each of the functional units described below.

[0036] Here, the program executed by the CPU 31 can be provided to the server in a state where it is stored in a computer-readable recording medium such as a magnetic recording medium (magnetic tape, magnetic disk, etc.), an optical recording medium (optical disk, etc.), a magneto-optical recording medium, a semiconductor memory, etc. Also, the program executed by the CPU 31 may be provided to the server using a communication means such as the Internet.

In addition, the HPS 21 is provided with an adjustment unit 213 and a power receiving path 214 for the power electronics device 211. The adjustment unit 213, which is an example of a load, adjusts temperature and humidity. The adjustment unit 213 is provided with a motor (not shown). This motor operates by receiving power that has been converted by the power conversion device 211 to a specific voltage and a specific frequency.

[0038] In this embodiment, the AF 212 is electrically connected in parallel to the power receiving path 214 of the power electronics device 211. The AF 212 adjusts the apparent power in the power receiving path 214 by supplying a current to the power receiving path 214 of the power electronics device 211.

[0039] FIG. 4 is a diagram showing the functional configuration of the calculation server 30. As shown in FIG. The calculation server 30 includes an acquisition unit 301 , a storage unit 302 , a usage amount calculation unit 303 , a set value calculation unit 304 , an available amount calculation unit 305 , a margin calculation unit 306 , and a transmission unit 307 . The acquisition unit 301, which is an example of an acquisition means, acquires information transmitted to the calculation server 30 or information input to the calculation server 30. The information acquired by the acquisition unit 301 is stored in the storage unit 302. The storage unit 302 stores information. The information stored in the storage unit 302 will be described in detail later.

[0040] The usage calculation unit 303 calculates a current value used in the HPS 21 in association with operation for adjusting the temperature and humidity of the HPS 21. The current value used in the HPS 21 in association with operation for adjusting the temperature and humidity of the HPS 21 is hereinafter referred to as usage. In this embodiment, the usage of the HPS 21 is calculated using detection value information. More specifically, the usage calculation unit 303 calculates the usage of the power electronics device 211 of the HPS 21 and the usage of the AF 212 of the HPS 21. The usage calculation unit 303 also calculates past usage and future usage of the power electronics device 211 and the AF 212.

[0041] The setting value calculation unit 304 calculates future setting values ​​for the HPS 21. The setting value calculation unit 304 calculates future setting values ​​for the HPS 21 based on future weather prediction results, a usage schedule for the HPS 21, and the like.

[0042] The possible amount calculation unit 305, which is an example of a capacity calculation means, calculates a future adjustable amount of the HPS 21. More specifically, the possible amount calculation unit 305 calculates a future adjustable amount of the HPS 21 based on the result of calculation by the usage amount calculation unit 303 as the future usage amount of the HPS 21. The possible amount calculation unit 305 also calculates the adjustable amount of the power electronics device 211 and the adjustable amount of the AF 212.

[0043] The margin calculation unit 306, which is an example of a margin calculation means, calculates a current value that the HPS21 can further supply to adjust the apparent power in the electric wire when the HPS21 is adjusting the apparent power in the electric wire. In other words, the margin calculation unit 306 calculates a margin up to the limit of the current value that the HPS21 can supply to adjust the apparent power in the electric wire when the HPS21 is adjusting the apparent power in the electric wire. Hereinafter, the margin up to the limit of the current value that the HPS21 can supply to adjust the apparent power in the electric wire when the HPS21 is adjusting the apparent power in the electric wire will be referred to as a margin. The transmission unit 307 as an example of an output unit transmits the information generated by the possible amount calculation unit 305 and the margin calculation unit 306 to the instruction server 40 .

[0044] 5 is a diagram showing a relationship management table. The relationship management table is a table for managing the relationship between the HPS 21 and the electric wires, etc. The relationship management table is stored in the storage unit 302. In the relationship management table, the HPS identification information is shown for "HPS." The letters "A" through "J" added to the "21" of "HPS" each indicate which of the multiple HPSs 21 it is.

[0045] In the relationship management table, the electric wire identification information is shown in the “passing electric wire.” The electric wire identification information shown in the “passing electric wire” is the electric wire identification information of the electric wire passed through in the supply of electric power to the “HPS.” Additionally, the "transit power line" is indicated with a "supply side" and a "receiving side." The "supply side" means that it is located on the power supply side of the power system 10 (see FIG. 1 ) rather than the "receiving side." Here, "14" indicated next to "supply side" means that it is the supply side distribution line 14. Additionally, "17" indicated next to "receiving side" means that it is the receiving side distribution line 17. Additionally, "A" through "E" added together with "17" are pieces of information for identifying which of the multiple receiving side distribution lines 17 it is.

[0046] In the relationship management table, ten "HPS" are associated with the "via line" "14," whereas two "HPS" are associated with each of the "via lines" "17A" to "17E." In other words, in this embodiment, the number of HPS 21 to which power is supplied via one supply-side distribution line 14 is greater than the number of HPS 21 to which power is supplied via one receiving-side distribution line 17. The "passing electric wire" in the relationship management table is set in advance by the user of the power control system 1.

[0047] In the relationship management table, the capacity of the current value that the HPS21 can generate is indicated in "capacity." In other words, the maximum current value that the HPS21 can generate is indicated in "capacity." The "power conversion device" in "capacity" indicates the maximum current value that the power conversion device 211 can generate. Furthermore, the "AF" in "capacity" indicates the maximum current value that the AF212 can generate. The “capacity” in the relationship management table is set in advance by the user of the power control system 1.

[0048] An example of the contents of the relationship management table will be described below. "HPS" specified by "21A" is associated with "14" as the "via line" on the "supply side", with "17A" as the "via line" on the "receiving side", with "10" as the "capacity" of the "power conversion device", and with "20" as the "capacity" of "AF". In the illustrated example, in each "HPS," the "capacity" of the "AF" is greater than the "capacity" of the "power conversion device," but this is not limited to the above. An "HPS" in which the "capacity" of the "power conversion device" is greater than the "capacity" of the "AF" may also be provided. Also, an "HPS" in which the "capacity" of the "power conversion device" and the "capacity" of the "AF" are the same may also be provided.

[0049] FIG. 6(a) is a diagram showing a past information management table, and FIG. 6(b) is a diagram showing a future information management table. The past information management table is a table for managing past information, and the future information management table is a table for managing future information. Both the past information management table and the future information management table are stored in the storage unit 302. In addition, both the past information management table and the future information management table are provided for each HPS 21. The past information management table shown in FIG. 6(a) and the future information management table shown in FIG. 6(b) are both intended for an HPS 21 whose HPS identification information is "21A". In the following, the explanation will be given assuming that the current date is "February 9, 2020."

[0050] 6(a), the "date and time" indicates the date and time indicated in the time information transmitted from the set value sensor 23 or the environment sensor 24. When the time information is acquired by the acquisition unit 301, the date and time indicated in the acquired time information is written in the "date and time" in the past information management table. In the past information management table, the day of the week corresponding to the date and time is indicated in the "day of the week" field.

[0051] Furthermore, in the past information management table, the "weather" field indicates the weather in the area where the HPS 21 is located. This "weather" is the weather at the associated "date and time." Furthermore, in the past information management table, the temperature in the area where the HPS 21 is located is shown in the "Temperature (°C)" column. This "Temperature (°C)" is the temperature at the associated "Date and Time." Furthermore, in the past information management table, the humidity in the area where the HPS 21 is located is indicated in the "humidity (%)" field. This "humidity (%)" is the humidity at the associated "date and time." When the detection value information transmitted from the environmental sensor 24 is acquired by the acquisition unit 301, the detection values ​​indicated in the acquired detection value information are written into "Weather," "Temperature (℃)," and "Humidity (%)" in the past information management table.

[0052] In the past information management table, the operation history of the HPS21 at the "date and time" is shown in "operation history". An "o" shown in "operation history" means that the HPS21 was operating to adjust the temperature or humidity. Also, a "-" shown in "operation history" means that the HPS21 was not operating. In the past information management table, the setting value of the HPS 21 at the "date and time" is shown in the "setting value". The "temperature (°C)" in the "setting value" refers to the temperature setting value of the HPS 21. Also, the "humidity (%)" in the "setting value" refers to the humidity setting value of the HPS 21. When the detection value information transmitted from the set value sensor 23 is acquired by the acquisition unit 301, the detection value indicated in the acquired detection value information is written in the "temperature (°C)" and "humidity (%)" in the past information management table. Furthermore, when the detection value information is transmitted from the set value sensor 23 together with time information, "o" is written in the "operation history" associated with the "date and time" indicated in this time information. In contrast, when the set value sensor 23 transmits time information but does not transmit detection value information, "-" is written in the "operation history" associated with the "date and time" indicated in this time information.

[0053] In the past information management table, the usage calculated by the usage calculation unit 303 is indicated in "usage amount." "Power electronics device" in "usage amount" refers to the usage amount of the power electronics device 211. Furthermore, "AF" in "usage amount" refers to the usage amount of the AF 212.

[0054] An example of the contents of the past information management table will be described below. The "date and time" specified from "2020 / 02 / 03 / 9:00" is associated with the "day of the week" of the "month", the "weather" of "sunny", the "temperature (℃)" of "5", the "humidity (%)" of "45", the "operation history" of "〇", the "temperature (℃)" of the "set value" of "22", and the "humidity (%)" of the "set value" of "60".

[0055] In the future information management table shown in Fig. 6(b), future dates and times are shown for each predetermined time period in the "date and time" column. The predetermined time period may be any time period, but is, for example, three hours. In the future information management table, the day of the week corresponding to the date and time is indicated in the "day of the week" field. Furthermore, in the future information management table, the "predicted weather" indicates the results of weather forecasts for the area in which the HPS 21 is installed. This weather forecast is the weather forecast result for the associated "date and time." Furthermore, in the future information management table, the "Predicted temperature (°C)" indicates the predicted temperature in the area where the HPS 21 is located. This predicted temperature is the predicted temperature at the associated "date and time." Furthermore, in the future information management table, the predicted humidity in the area where the HPS 21 is installed is shown in the "Predicted Humidity (%)" field. This humidity prediction result is the predicted humidity at the associated "Date and Time."

[0056] The calculation server 30 may acquire, via a network (not shown), the results of forecasting the weather, temperature, and humidity at a target "date and time" in the area where the HPS 21 is installed. Also, a user of the power control system 1 may input the weather, temperature, and humidity at a target "date and time" in the area where the HPS 21 is installed. When the forecast results sent to the calculation server 30 or the information input by the user are acquired by the acquisition unit 301, they are written into the "day of the week," "forecasted weather," "forecasted temperature (°C)," and "forecasted humidity (%)" associated with the target "date and time" in the future information management table.

[0057] Furthermore, in the future information management table, the "operation schedule" indicates the operation schedule for adjusting the temperature and humidity of the HPS21. An "o" shown in the "operation schedule" indicates that the HPS21 is scheduled to operate on the associated "date and time". Furthermore, a "-" shown in the "operation schedule" indicates that the HPS21 is not scheduled to operate on the associated "date and time". The calculation server 30 may acquire information on the operation schedule of the HPS 21 at the target "date and time" via a network (not shown). Information on the operation schedule of the HPS 21 includes information on the target for which the HPS 21 adjusts the temperature and humidity. Hereinafter, information on the target for which the HPS 21 adjusts the temperature and humidity is referred to as target information. Examples of the target information include information on whether or not the power consumption facility 20 in which the HPS 21 is installed is scheduled to be used. Examples of the target information include information on whether or not the specific target is scheduled to be used, in the case where the HPS 21 adjusts the temperature and humidity of the specific target. In addition, when there is a plan to use the power consumption facility 20 in which the HPS 21 is installed or a plan to use a specific target, the user of the power control system 1 may input the operation schedule of the HPS 21 at the target "date and time" to generate the target information. When the target information transmitted to the calculation server 30 via the network or the target information input by the user is acquired by the acquisition unit 301, it is written into the "operation schedule" associated with the target "date and time" in the future information management table. Note that the target information is information on the HPS 21. Therefore, in a broad sense, the target information can also be regarded as system information relating to the HPS21.

[0058] Furthermore, in the future information management table, the "predicted setting value" indicates the calculation result by the setting value calculation unit 304 as the future setting value of the HPS 21. The "temperature (°C)" of the "predicted setting value" is the setting value of the temperature of the HPS 21 at the associated "date and time". Furthermore, the "humidity (%)" of the "predicted setting value" is the setting value of the humidity of the HPS 21 at the associated "date and time".

[0059] In the future information management table, the "predicted usage" indicates the calculation result by the usage calculation unit 303 as the future usage of the HPS 21. The "power electronics device" in the "predicted usage" is the usage of the power electronics device 211 at the associated "date and time". Furthermore, the "AF" in the "predicted usage" is the usage of the AF 212 at the associated "date and time".

[0060] In the future information management table, the "adjustable amount" indicates the calculation result of the adjustable amount of the HPS 21 by the adjustable amount calculation unit 305. The "power electronics device" in the "adjustable amount" is the adjustable amount of the power electronics device 211 at the associated "date and time". Furthermore, the "AF" in the "adjustable amount" is the adjustable amount of the AF 212 at the associated "date and time".

[0061] An example of the contents of the future information management table will be described below. A "date and time" specified from "2020 / 02 / 10 / 9:00" is associated with a "day of the week" of a "month", a "forecasted weather" of "rain", a "forecasted temperature (℃)" of "3", a "forecasted humidity (%)" of "85%", and a "operation schedule" of "〇".

[0062] (Processing of the setting value calculation unit 304) Next, a description will be given of the processing of the set value calculation unit 304. The set value calculation unit 304 calculates the set value of the HPS 21 at the "date and time" where "◯" is indicated in the "operation schedule" in the future information management table (see FIG. 6(b)).

[0063] The set value calculation unit 304 may calculate the set values ​​of the temperature and humidity of the HPS 21 from the viewpoint of keeping the temperature and humidity of the target of adjustment by the HPS 21 at a predetermined value. The set value calculation unit 304 may also calculate the set values ​​of the temperature and humidity of the HPS 21 based on the "predicted weather," "predicted temperature (°C)," and "predicted humidity (%)" for the target "date and time." The set value calculation unit 304 may also calculate the set value of the temperature of the HPS 21 to be higher the lower the "predicted temperature (°C)" for the target "date and time" when the heating function of the HPS 21 is used. The set value calculation unit 304 may also calculate the set value of the temperature of the HPS 21 to be lower the higher the "predicted temperature (°C)" for the target "date and time" when the cooling function of the HPS 21 is used. In addition, the setting value calculation unit 304 may calculate a lower humidity setting value for the HPS21 the higher the "predicted humidity (%)" for the target "date and time" is, or may calculate a higher humidity setting value for the HPS21 the lower the "predicted humidity (%)" for the target "date and time" is. The setting value calculation unit 304 may also calculate future setting values ​​for the HPS 21 using information in the past information management table (see FIG. 6(a)). The setting value calculation unit 304 extracts a "date and time" from the past information management table that is associated with the same or similar "day of the week," "weather," "temperature (°C)," and "humidity (%)" as the "day of the week," "predicted weather," "predicted temperature (°C)," and "predicted humidity (%)" for the target "date and time" in the future information management table. The setting value calculation unit 304 may then calculate the setting value for the target "date and time" based on the "setting value" associated with the extracted "date and time."

[0064] When the setting value of HPS21 for each "date and time" is calculated by the setting value calculation unit 304, the calculation results by the setting value calculation unit 304 are written into the "Temperature (°C)" and "Humidity (%)" in the "Predicted setting value" in the future information management table, as shown in FIG. 7(a).

[0065] (Processing of the usage amount calculation unit 303) Next, the process of the usage calculation unit 303 will be described. The usage calculation unit 303 calculates the usage of the HPS 21 at each "date and time" in the past information management table (see FIG. 6(a)). The usage amount calculation unit 303 calculates the usage amount of the power electronics device 211 and the usage amount of the AF212 at the target "date and time" by using information on "weather," "temperature (°C)," "humidity (%)," "operation history," and "setting value" associated with the target "date and time." The usage amount calculation unit 303 may calculate the usage amount of the power electronics device 211 at the target "date and time" to be larger as the difference between the "temperature (°C)" and "humidity (%)" associated with the target "date and time" and the "temperature (°C)" and "humidity (%)" in the "setting value" is larger. Furthermore, the usage amount calculation unit 303 calculates the usage amount of the AF212 based on the calculated usage amount of the power electronics device 211. The usage amount calculation unit 303 may calculate the usage amount of the AF212 to be larger as the usage amount of the power electronics device 211 is larger. In addition, if the "operating history" associated with the target "date and time" shows "-", the usage calculation unit 303 calculates the usage of the power conversion device 211 and the usage of the AF 212 at this "date and time" as both "0".

[0066] When the usage amount of the power conversion device 211 and the usage amount of the AF 212 at each “date and time” is calculated by the usage amount calculation unit 303, the calculation results by the usage amount calculation unit 303 are written in the “Usage amount” of “Power conversion device” and “AF” in the past information management table, as shown in FIG. 7(b). The "usage amount" written in the past information management table may be an actual measurement value of the usage amount. In this case, the set value sensor 23 detects the usage amount of the power electronics device 211 and the usage amount of the AF 212 at each "date and time". When the detection value detected by the set value sensor 23 is acquired by the acquisition unit 301, this detection value is written in the "usage amount" of the "power electronics device" and "AF" associated with each "date and time" in the past information management table.

[0067] Furthermore, the usage calculation unit 303 calculates the usage of the HPS 21 at each "date and time" in the future information management table (see FIG. 7(a)). The usage calculation unit 303 calculates the usage of the power electronics device 211 and the usage of the AF 212 at the target "date and time" by using information on "predicted weather," "predicted temperature (°C)," "predicted humidity (%)," "operation schedule," and "predicted set value" associated with the target "date and time." The usage calculation unit 303 may calculate the future usage of the power electronics device 211 and the usage of the AF 212 by the same method as the method described above for calculating the past usage. The usage calculation unit 303 may also calculate the future usage of the power electronics device 211 and the AF 212 using information in the past information management table. The usage calculation unit 303 extracts a "date and time" from the past information management table associated with "day of the week," "weather," "temperature (°C)," "humidity (%)," and "setting value" that are the same as or close to the "day of the week," "forecast weather," "forecast temperature (°C)," "forecast humidity (%)," and "forecast setting value" at the target "date and time" in the future information management table. Then, the usage at the target "date and time" may be calculated based on the "usage" associated with the extracted "date and time."

[0068] When the usage amount of the power conversion device 211 and the usage amount of the AF 212 at each “date and time” is calculated by the usage amount calculation unit 303, the calculation results by the usage amount calculation unit 303 are written in the “predicted usage amount” of the “power conversion device” and the “AF” in the future information management table, as shown in FIG. 7(c).

[0069] 8 is a flowchart showing the flow of the possible amount calculation process. The possible amount calculation process is a process in which the possible amount calculation unit 305 calculates the adjustable amount of the HPS 21. In this embodiment, when a request for adjustment of apparent power in a specific electric wire in the power system 10 is transmitted from the instruction server 40 to the calculation server 30, the possible amount calculation process is started. Note that the request transmitted from the instruction server 40 to the calculation server 30 includes electric wire identification information for identifying the electric wire to be adjusted. The possible amount calculation unit 305 extracts an HPS 21 associated with the electric wire that is the target of adjustment requested by the instruction server 40 (step (hereinafter referred to as "S") 101). More specifically, the possible amount calculation unit 305 refers to the relationship management table (see FIG. 5). Then, the possible amount calculation unit 305 extracts an HPS 21 identified from the "HPS" associated with the "passing electric wire" in the electric wire identification information of the electric wire that is the target of adjustment.

[0070] The possible amount calculation unit 305 calculates the adjustable amount of the HPS 21 by using the future information management table (see FIG. 7(c)) for the extracted HPS 21 (S102). A description will be given of an example of a method for calculating the adjustable amount by the adjustable amount calculation unit 305. In the following, an example will be described in which the usage amount of the power electronics device 211 and the usage amount of the AF 212 at "2020 / 02 / 10 / 9:00" of the HPS 21 of "21A" is calculated. The available amount calculation unit 305 refers to the relationship management table (see FIG. 5). Then, the value obtained by subtracting the "predicted usage amount" associated with the target "date and time" in the future information management table (see FIG. 7(c)) from the "capacity" associated with the target "HPS" is calculated as the adjustable amount of the HPS 21 at the target "date and time". In this example, the "predicted usage amount" of the "power electronics device" associated with the target "date and time" "2020 / 02 / 10 / 9:00" in the future information management table is subtracted from the "capacity" of the "power electronics device" associated with "21A" in the relationship management table, "3". Then, the value "10-3=7" obtained by the subtraction is set as the adjustable amount of the power electronics device 211. Similarly, the adjustable amount of "AF" at "2020 / 02 / 10 / 9:00" is calculated as "20-6=14".

[0071] The possible amount calculation unit 305 calculates the adjustable amount of the power electronics device 211 and the adjustable amount of the AF 212 at each "date and time" in the future information management table (see FIG. 7(c)). In addition, although not shown, the possible amount calculation unit 305 calculates the adjustable amount for each HPS 21 extracted in step 101. When the adjustable amount of the power conversion device 211 and the adjustable amount of the AF 212 at each "date and time" are calculated by the possible amount calculation unit 305, the calculation results by the possible amount calculation unit 305 are written in the "adjustable amount" of "power conversion device" and "AF" in the future information management table, as shown in FIG. 9.

[0072] The possible amount calculation unit 305 judges whether the calculated adjustable amount satisfies a transmission condition (S103). The transmission condition is a condition determined for judging whether information on the adjustable amount calculated by the possible amount calculation unit 305 is to be transmitted to the instruction server 40. In this embodiment, the transmission condition is determined such that the adjustable amount is equal to or greater than a predetermined ratio of a current value required to adjust the apparent power in the electric wire. The predetermined ratio may be any ratio, but is, for example, equal to or greater than 1%. The possible amount calculation unit 305 determines whether or not the transmission condition is satisfied for each calculated possible adjustment amount.

[0073] The transmitting unit 307 transmits to the instruction server 40 the adjustable amount information indicating the adjustable amount that satisfies the transmission condition, together with time information indicating the “date and time” with which this adjustable amount is associated, and HPS identification information that identifies the target HPS 21 (S104). On the other hand, the transmitting unit 307 does not transmit to the instruction server 40 information on the adjustable amount that does not satisfy the transmission condition. The instruction server 40 determines the HPS 21 to be used for adjusting the apparent power in the electric wire, the current value to be supplied for the adjustment, and the time period for the adjustment, based on the available amount information, time information, and HPS identification information transmitted from the calculation server 30. Then, the instruction server 40 transmits an instruction to the HPS 21 for adjusting the apparent power in the electric wire to the calculation server 30. This instruction includes information such as the HPS identification information of the HPS 21 to be used for adjusting the apparent power in the electric wire, the current value to be supplied for the adjustment, and the time period for the adjustment. Furthermore, the information on the current value to be supplied for the adjustment includes information on the current value to be supplied by the power conversion device 211 and information on the current value to be supplied by the AF 212. Upon receiving the instruction, the calculation server 30 instructs the HPS 21, which is the target of the instruction, to adjust the apparent power in the electric wire by the current value indicated in the instruction during the time period indicated in the instruction. Upon receiving the instruction, the HPS 21 supplies current from the power conversion device 211 and the AF 212 to the electric wire.

[0074] As described above, in this embodiment, the possible amount calculation unit 305 calculates an index related to the ability of the HPS 21 to adjust the apparent power in the electric wire when the HPS 21 adjusts the temperature and humidity based on the system information. This index is, for example, the adjustable amount. In this case, instruction server 40 can determine the current value to be supplied by HPS 21 in order to adjust the apparent power in the electric wire of electric power system 10, based on the adjustment possible amount calculated by possible amount calculation unit 305. Furthermore, HPS 21 supplies the electric wire with the current value determined by instruction server 40 in accordance with an instruction from instruction server 40. Therefore, when HPS 21 is adjusting temperature and humidity, adjustment of the apparent power in the electric wire of electric power system 10 by HPS 21 can be realized.

[0075] In this embodiment, the possible amount calculation unit 305 determines whether the calculated adjustable amount satisfies the transmission condition. Then, the transmission unit 307 transmits possible amount information indicating the adjustable amount determined by the possible amount calculation unit 305 to satisfy the transmission condition to the instruction server 40. That is, in this embodiment, the transmission unit 307 outputs possible amount information regarding the adjustable amount that satisfies the condition set for the adjustment of the apparent power. In this case, it is possible to prevent possible amount information that is not suitable for adjusting the apparent power in the power line from being output, compared to when possible amount information is output regardless of whether the adjustable amount satisfies the transmission conditions.

[0076] Furthermore, in this embodiment, possible amount information on the adjustable amount for the HPS 21 that receives power via the electric wire that is the target of apparent power adjustment is transmitted to instruction server 40. In other words, in this embodiment, the condition for transmission unit 307 to output the possible amount information is determined to be that the adjustable amount indicated in the possible amount information is the adjustable amount calculated for the HPS 21 that receives power via the electric wire that is the target of apparent power adjustment. In this case, it is possible to prevent the output of possible amount information about HPS21 that does not receive power via the power line that is the target of adjustment, compared to when possible amount information is output regardless of whether the adjustable amount satisfies the conditions.

[0077] Furthermore, in this embodiment, the transmission conditions are defined with respect to the ability to adjust the apparent power. In this case, it is possible to prevent the output of possible amount information that is not suitable for the ability to adjust the apparent power in the power line, compared to when possible amount information is output regardless of whether the adjustable amount satisfies the transmission conditions.

[0078] Moreover, in this embodiment, the transmission conditions are determined based on the relationship between the ability to adjust the apparent power and the degree of adjustment required for the apparent power in the power lines of the power system 10. In this case, it is possible to prevent the output of possible amount information that is not appropriate for the relationship between the adjustable amount and the degree of adjustment required, compared to when possible amount information is output regardless of whether the adjustable amount satisfies the transmission conditions.

[0079] In this embodiment, the possible amount calculation unit 305 calculates the possible adjustment amount by the power electronics device 211 and the possible adjustment amount by the AF 212. In this case, the instruction server 40 can determine a current value to be supplied by the power conversion device 211 and a current value to be supplied by the AF 212 in order to adjust the apparent power in the electric wire of the electric power system 10, based on the adjustment possible amount calculated by the adjustment possible amount calculation unit 305. Furthermore, the power conversion device 211 and the AF 212 supply the current value determined by the instruction server 40 to the electric wire in accordance with an instruction from the instruction server 40. Therefore, when the HPS 21 is adjusting the temperature and humidity, the adjustment of the apparent power in the electric wire of the electric power system 10 by the power conversion device 211 and the AF 212 can be realized.

[0080] Furthermore, in this embodiment, the system information includes target information regarding the target for which the HPS 21 adjusts the temperature and humidity. In this case, it is possible to calculate an adjustable amount suitable for the target to be subjected to temperature and humidity adjustment by the HPS 21, compared to a case where the adjustable amount calculation unit 305 calculates the adjustable amount without using the target information.

[0081] In this embodiment, the possible amount calculation unit 305 calculates the adjustable amount as the subtraction value of the “predicted usage amount” shown in the future information management table (see FIG. 7(c)) for the capacity of both the power conversion device 211 and the AF 212, but is not limited to this. The possible amount calculation unit 305 may further subtract a correction value from the subtraction value calculated for the power electronics device 211 to calculate the value obtained as the adjustable amount of the power electronics device 211. The correction value may be determined based on a current value supplied to the power electronics device 211 for adjusting temperature and humidity. Furthermore, the possible amount calculation unit 305 may calculate the adjustable amount of the power electronics device 211 so that it is lower than the adjustable amount of AF212. In this case, the adjustable amount of AF212 is regarded as a first index related to a predetermined capability. Furthermore, the adjustable amount of the power electronics device 211 is regarded as a second index related to a capability lower than the capability of AF212.

[0082] If the adjustable amount of power conversion device 211 is calculated to be larger than the adjustable amount of AF212, the current value supplied to power conversion device 211 may be larger than the current value supplied to AF212 for adjusting the apparent power in the electric wire based on this calculation result. In this case, the current value supplied from power conversion device 211 to a motor (not shown) of adjustment unit 213 becomes smaller, which may affect the function of adjusting temperature and humidity by HPS21. Therefore, by calculating the adjustable amount of the power electronics device 211 to be lower than the adjustable amount of the AF 212, it is possible to suppress the effect on the temperature and humidity adjustment function of the HPS 21.

[0083] 10(a) is a diagram showing an adjustment management table. The adjustment management table is a table for managing the HPS 21 that is adjusting the apparent power in the electric wire of the power system 10. The adjustment management table is stored in the storage unit 302. In the following, it is assumed that at 0:00 on February 10, 2020, the power conversion device 211 in the "21A" HPS 21 supplies a current of "5" and the AF 212 supplies a current of "10", thereby causing the HPS 21 to adjust the apparent power in the electric wire.

[0084] In the adjustment management table, the "date and time" column shows the current time and future dates and times for each predetermined time period. The predetermined time period may be any time period, but is, for example, three hours. In the adjustment management table, the "predicted usage" indicates the calculation result of the usage calculation unit 303 as the usage of the HPS 21 at the "date and time." This "predicted usage" is the same information as the "predicted usage" in the future information management table (see FIG. 7(c)). Moreover, in the adjustment management table, the "predicted adjustment amount" indicates a predicted value of the current supplied by the HPS21 to adjust the apparent power in the electric wire. This predicted value is a predicted value at the associated "date and time". Here, the "power electronics device" of the "predicted adjustment amount" is a predicted value of the current supplied by the power electronics device 211. Moreover, the "AF" of the "predicted adjustment amount" is a predicted value of the current supplied by the AF212. In this embodiment, the current value being supplied by the HPS21 is written to the "predicted adjustment amount" at each "date and time".

[0085] In the adjustment management table, the "margin" indicates the calculation result of the margin calculation unit 306 as the margin of the HPS 21. This margin is the margin at the associated "date and time." The "power electronics device" in the "margin" is the margin of the power electronics device 211. Furthermore, the "AF" in the "margin" is the margin of the AF 212.

[0086] In the adjustment management table, the "threshold" indicates a threshold for the margin. This threshold is used to determine whether or not to send a warning about the margin to the instruction server 40. The "power electronics device" in the "threshold" is a threshold for the margin of the power electronics device 211. The "AF" in the "threshold" is a threshold for the margin of the AF212.

[0087] The "threshold" is set in the calculation server 30 based on the lifespan of the power electronics device 211 or AF212. The "threshold" may be set higher as the lifespan of the power electronics device 211 or AF212 approaches its limit. The lifespan of the power electronics device 211 or AF212 may be set based on the voltage value applied to the power electronics device 211 or AF212, the period of use of the power electronics device 211 or AF212, the ambient temperature of the HPS21, etc. Furthermore, the "threshold" is set based on the extent to which the power electronics device 211 and the AF 212 are used to adjust temperature and humidity. The "threshold" may be set higher as the "predicted usage" increases. In the illustrated example, in the "power electronics device" and the "AF", the "threshold" associated with a "predicted usage" showing a value of 2 or more is set higher than the "threshold" associated with a "predicted usage" of "0".

[0088] (Processing of margin calculation unit 306) Next, the process of the margin calculation unit 306 will be described. The margin calculation unit 306 calculates the margin of the HPS 21 using the adjustment management table. A description will be given of an example of a method by which the margin calculation unit 306 calculates the margin of the HPS 21. The following describes a method for calculating the margin of the "power conversion device" and the margin of "AF" of the HPS 21 of "21A" at "2020 / 02 / 10 / 9:00".

[0089] The margin calculation unit 306 calculates the relationship management table (see FIG. 5). Then, the margin calculation unit 306 calculates the margin of the HPS 21 at the target "date and time" by subtracting the "predicted adjustment amount" associated with the target "date and time" in the adjustment management table (see FIG. 10(a)) from the "capacity" associated with the target "HPS". In this example, the margin calculation unit 306 subtracts "5", which is the "predicted adjustment amount" of the "power electronics device" associated with the target "date and time" "2020 / 02 / 10 / 9:00" in the adjustment management table, from "10", which is the "capacity" of the "power electronics device" associated with "21A" in the relationship management table. Then, the value "10-5=5" obtained by the subtraction is set as the margin of the power electronics device 211. Similarly, the margin of the "AF" at "2020 / 02 / 10 / 9:00" is calculated as "20-10=10".

[0090] The margin calculation unit 306 calculates the margin of the power electronics device 211 and the margin of the AF 212 at each "date and time" in the adjustment management table. Although not shown, the margin calculation unit 306 also calculates the margin for each HPS 21 used to adjust the apparent power in the electric wire of the power system 10. When the margin calculation unit 306 calculates the margin of the power electronics device 211 and the margin of the AF 212 at each “date and time”, the calculation results by the margin calculation unit 306 are written in the “margin” of the “power electronics device” and “AF” in the adjustment management table, as shown in FIG. 10 .

[0091] Furthermore, after calculating the margin, the margin calculation unit 306 determines whether the calculated margin has reached a threshold. More specifically, the margin calculation unit 306 extracts the "margin" that indicates a value equal to or less than the "threshold" at each "date and time". The transmission unit 307 then transmits warning information regarding the extracted "margin" to the instruction server 40 together with time information indicating the "date and time" with which the "margin" is associated and HPS identification information that identifies the target HPS 21. The warning information may be information for notifying the instruction server 40 that the margin of the HPS 21 will be insufficient at the target "date and time" as a result of the target HPS 21 being used to adjust temperature and humidity. In this example, a warning is sent about the "margin" of the "power conversion device" and the "margin" of the "AF" at "2020 / 02 / 10 / 9:00" when the "margin" is below the "threshold", and about the "margin" of the "power conversion device" and the "margin" of the "AF" at "2020 / 02 / 10 / 18:00".

[0092] Furthermore, transmission unit 307 may transmit information indicating the margin calculated by margin calculation unit 306, together with time information indicating the “date and time” with which this margin is associated, and HPS identification information identifying the target HPS 21, to instruction server 40. Based on the margin information transmitted from transmission unit 307, instruction server 40 appropriately changes the current value to be supplied to the HPS 21 being adjusted.

[0093] As described above, in this embodiment, the margin calculation unit 306 calculates an index related to the margin of the adjustment capability when the HPS 21 adjusts the apparent power in the electric wire. This index is, for example, a margin. In this case, the instruction server 40 can change the current value to be supplied by the HPS 21 in order to adjust the apparent power in the electric wire of the electric power system 10, based on the margin calculated by the margin calculation unit 306.

[0094] Furthermore, in this embodiment, the margin calculation unit 306 determines whether the calculated margin has reached a threshold value. Then, the transmission unit 307 transmits warning information related to the margin determined by the margin calculation unit 306 to have reached the threshold value to the instruction server 40. In other words, in this embodiment, the transmission unit 307 outputs information related to the HPS 21 when the margin satisfies a condition defined for the margin. The condition defined for the margin is, for example, that the margin has reached a threshold value. In this case, compared to a case where information about the margin is output regardless of whether the margin calculated by the margin calculation unit 306 satisfies the conditions, it is possible to prevent information about HPS21 for which a margin that is not suitable for changing the current value to be supplied to HPS21 from being output.

[0095] In this embodiment, the conditions defined regarding the margin are determined based on the life span of the HPS 21. In this case, the value of the current supplied by the HPS 21 can be changed to adjust the apparent power in the electric wire, taking into account the life span of the HPS 21.

[0096] Furthermore, in this embodiment, the conditions set regarding the margins are set based on the use of the HPS 21 for adjusting the temperature and humidity. In this case, the value of the current supplied by the HPS 21 for adjusting the apparent power in the electric wire can be changed, taking into consideration the use of the HPS 21 for adjusting the temperature and humidity.

[0097] In this embodiment, the setting value calculation unit 304 calculates the future setting value of the HPS21, the usage calculation unit 303 calculates the future usage amount of the HPS21, and the possible amount calculation unit 305 calculates the future adjustable amount of the HPS21, but this is not limited to the above. The set value calculation unit 304 may calculate the set value of the HPS 21 at the current time. Furthermore, the usage amount calculation unit 303 may calculate the usage amount of the HPS 21 at the current time. Furthermore, the possible amount calculation unit 305 may calculate the adjustment possible amount of the HPS 21 at the current time. Here, the "index related to the ability of the HPS 21 to adjust the apparent power in the electric wire when the HPS 21 adjusts the temperature and / or humidity" includes not only the future possible adjustment amount but also the current possible adjustment amount.

[0098] In addition, in this embodiment, when the instruction server 40 requests the calculation server 30 to adjust the apparent power in a state where the usage calculation unit 303 has calculated the usage and the setting value calculation unit 304 has calculated the setting value in advance, the possible amount calculation process (see FIG. 8) is started, but is not limited to this. The instruction server 40 may request the calculation server 30 to adjust the apparent power in a state where the usage calculation unit 303 has not yet calculated the usage amount and the setting value calculation unit 304 has not yet calculated the setting value. In this case, when the calculation server 30 receives the request for adjustment, the usage calculation unit 303 calculates the usage amount and the setting value calculation unit 304 calculates the setting value. Then, the possible amount calculation unit 305 calculates the possible adjustment amount based on the calculation results of the usage calculation unit 303 and the setting value calculation unit 304. Furthermore, the usage calculation unit 303 may calculate the usage, the setting value calculation unit 304 may calculate the setting value, and the possible amount calculation unit 305 may calculate the adjustable amount in a state where the instruction server 40 has not requested the calculation server 30 to adjust the apparent power. In this case, the transmission unit 307 may transmit information on the adjustable amount to the instruction server 40 in a state where the instruction server 40 has not requested the calculation server 30 to adjust the apparent power.

[0099] In addition, in this embodiment, information regarding the adjustable amount that satisfies the transmission condition is transmitted to the instruction server 40, but information regarding this adjustable amount may be transmitted to the instruction server 40 regardless of whether the adjustable amount satisfies the transmission condition. In addition, in this embodiment, information regarding the surplus amount that has reached the threshold is transmitted to the instruction server 40, but information regarding this surplus amount may be transmitted to the instruction server 40 regardless of whether the surplus amount has reached the threshold or not.

[0100] Furthermore, the "predicted adjustment amount" for each "date and time" in the adjustment management table (see FIG. 10(b)) may be updated every time an instruction for a current value to be supplied to the HPS 21 for adjusting the apparent power in the electric wire of the electric power system 10 is changed. In this case, the surplus amount calculation unit 306 may calculate the surplus amount and determine whether or not to transmit information regarding the surplus amount to the instruction server 40 based on the updated "predicted adjustment amount" every time the "predicted adjustment amount" is updated.

[0101] In the present embodiment, the possible amount calculation unit 305 calculates the adjustable amount of the power electronics device 211 to be smaller than the adjustable amount of the AF 212, but is not limited to this. The possible amount calculation unit 305 may calculate the adjustable amount of the power electronics device 211 to be larger than the adjustable amount of the AF 212.

[0102] Furthermore, the "operation schedule" in the future information management table shown in FIG. 6(b) may be written by a method different from the method described above. The calculation server 30 may estimate the future operation schedule of the HPS 21 based on the result of machine learning. More specifically, the calculation server 30 learns the relationship between the "day of the week", the use or non-use of the power consuming facility 20, and the operation or non-operation of the HPS 21, using as teacher data the "day of the week" at a specific "date and time" in the past information management table (see FIG. 6(a)), information on the use or non-use of the power consuming facility 20 in which the HPS 21 is installed at this "date and time", and the "operation history" at this "date and time". Based on the learning result, the calculation server 30 generates a learning model that outputs the operation schedule of the HPS 21 by inputting the "day of the week" at a specific "date and time" in the future information management table and the use or non-use of the power consuming facility 20 at this "date and time". Then, based on the generated learning model, the operation schedule of the HPS 21 may be estimated from the "day of the week" at a specific "date and time" in the future information management table and the use or non-use of the power consuming facility 20 at this "date and time". Furthermore, the estimated driving schedule may be written into the "driving schedule" for this "date and time".

[0103] Moreover, the "predicted setting value" in the future information management table shown in FIG. 6(b) may be written by a method different from the above-mentioned method. The set value calculation unit 304 may estimate the set value of the HPS 21 in the future based on the result of machine learning. More specifically, the set value calculation unit 304 learns the relationship between the "date and time", "day of the week", "weather", "temperature (°C)", "humidity (%)", "operation history", and the set value of the HPS 21, using the "date and time", "day of the week", "weather", "temperature (°C)", "humidity (%)", "operation history", and the "set value" associated with each other in the past information management table (see FIG. 6(a)) as teacher data. The set value calculation unit 304 generates a learning model that outputs the set value of the HPS 21 using the "date and time", "day of the week", "predicted weather", "predicted temperature (°C)", "predicted humidity (%)", and "operation schedule" associated with each other in the future information management table as inputs based on the learning result. Then, based on the generated learning model, the set value of the HPS 21 may be estimated from the "day of the week", "predicted weather", "predicted temperature (°C)", "predicted humidity (%)", and "operation schedule" at a specific "date and time" in the future information management table. Furthermore, the estimated setting value may be written to the "predicted setting value" at this "date and time".

[0104] Furthermore, the "projected usage amount" in the future information management table shown in FIG. 7(a) may be written by a method different from the above-mentioned method. The usage amount calculation unit 303 may estimate the future usage amount of the HPS 21 based on the result of machine learning. More specifically, the usage amount calculation unit 303 learns the relationship between the "date and time", "day of the week", "weather", "temperature (°C)", "humidity (%)", "operation history", "setting value", and "usage amount" associated with each other in the past information management table (see FIG. 7(b)) as teacher data, and the usage amount of the HPS 21. The usage amount calculation unit 303 generates a learning model that outputs the usage amount of the HPS 21 based on the learning result, using the "date and time", "day of the week", "forecast weather", "forecast temperature (°C)", "forecast humidity (%)", "operation schedule", and "forecast setting value" associated with each other in the future information management table as input. Then, based on the generated learning model, the usage amount of the HPS21 at a specific "date and time" may be estimated from the "day of the week," "forecast weather," "forecast temperature (°C)," "forecast humidity (%)," "operation schedule," and "forecast setting value" at this "date and time" in the future information management table. Furthermore, the estimated usage amount may be written in the "forecast usage amount" at this "date and time."

[0105] Further, in the present embodiment, the calculation server 30 is configured to calculate the ability of the HPS 21 to adjust the apparent power in the electric wire of the power system 10, but the present invention is not limited to this. For example, the HPS 21 may have the functions of the calculation server 30. In other words, the HPS 21 may be provided with a CPU 31 (see FIG. 2), a ROM 32, a RAM 33, a communication device 34, and a storage device 35 for implementing various functions. The HPS 21 may also have the functions of the calculation server 30, such as the acquisition unit 301, storage unit 302, usage amount calculation unit 303, setting value calculation unit 304, possible amount calculation unit 305, margin calculation unit 306, and transmission unit 307.

[0106] In addition, in the present disclosure, the parameters such as the usage amount, the adjustable amount, and the margin amount are current values, but the present disclosure is not limited to this. Each parameter may be any of the parameters described above as parameters related to apparent power.

[0107] Here, each of the embodiments described above can be understood as follows. The possible amount calculation unit 305 of this embodiment calculates the possible adjustment amount when the HPS 21 adjusts the temperature and / or humidity, based on the system information. In this case, instruction server 40 can determine the current value to be supplied by HPS 21 in order to adjust the apparent power in the electric wires of electric power system 10, based on the adjustment possible amount calculated by possible amount calculation unit 305. Therefore, when HPS 21 is adjusting the temperature and humidity, adjustment of the apparent power in the electric wires of electric power system 10 by HPS 21 can be realized.

[0108] Further, the headroom calculation unit 306 calculates the headroom when the HPS 21 adjusts the apparent power in the electric wire. In this case, the instruction server 40 can change the current value to be supplied by the HPS 21 in order to adjust the apparent power in the electric wire of the electric power system 10, based on the margin calculated by the margin calculation unit 306.

[0109] Furthermore, if the margin amount satisfies a condition set for the margin, the transmission unit 307 outputs information about the HPS 21. In this case, compared to a case where information about the margin is output regardless of whether the margin calculated by the margin calculation unit 306 satisfies the conditions, it is possible to prevent information about HPS21 for which a margin that is not suitable for changing the current value to be supplied to HPS21 from being output.

[0110] Conditions are also established based on the life span for HPS21. In this case, the value of the current supplied by the HPS 21 can be changed to adjust the apparent power in the electric wire, taking into account the life span of the HPS 21.

[0111] Conditions are also defined based on the use of HPS21 for temperature and / or humidity regulation. In this case, the value of the current supplied by the HPS 21 for adjusting the apparent power in the electric wire can be changed, taking into consideration the use of the HPS 21 for adjusting the temperature and humidity.

[0112] Furthermore, the transmitting unit 307 outputs possible amount information regarding the possible adjustment amount that satisfies the transmission condition determined for the adjustment of the apparent power. In this case, it is possible to prevent information regarding the adjustable amount that is not suitable for adjusting the apparent power in the power line from being output, compared to when information regarding the adjustable amount is output regardless of whether the adjustable amount satisfies the transmission conditions.

[0113] Also, the condition is that the adjustable amount is an adjustable amount calculated for the HPS 21 that receives power via the power line that is the target of the apparent power adjustment. In this case, it is possible to prevent the output of possible amount information about HPS21 that does not receive power via the power line that is the target of adjustment, compared to when possible amount information is output regardless of whether the adjustable amount satisfies the conditions.

[0114] Transmission conditions are also defined with respect to the ability to adjust apparent power. In this case, it is possible to prevent the output of possible amount information that is not suitable for the ability to adjust the apparent power in the power line, compared to when possible amount information is output regardless of whether the adjustable amount satisfies the transmission conditions.

[0115] The transmission conditions are also determined based on the relationship between the capabilities and the degree of adjustment required for the apparent power on the wire. In this case, it is possible to prevent the output of possible amount information that is not appropriate for the relationship between the adjustable amount and the degree of adjustment required, compared to when possible amount information is output regardless of whether the adjustable amount satisfies the transmission conditions.

[0116] Further, the possible amount calculation unit 305 calculates the possible adjustment amount by the power electronics device 211 and the possible adjustment amount by the AF 212 . In this case, the instruction server 40 can determine the current value to be supplied by the power conversion device 211 and the current value to be supplied by the AF 212 in order to adjust the apparent power in the electric wire of the electric power system 10, based on the adjustment possible amount calculated by the adjustment possible amount calculation unit 305. Therefore, when the HPS 21 is adjusting the temperature and humidity, the adjustment of the apparent power in the electric wire of the electric power system 10 by the power conversion device 211 and the AF 212 can be realized.

[0117] Moreover, the possible amount calculation unit 305 calculates the adjustable amount for a predetermined capacity for the AF 212, and calculates the adjustable amount for the power electronics device 211 for a capacity lower than that of the AF 212. In this case, it is possible to suppress the influence on the function of adjusting temperature and humidity by the HPS 21, compared to the case where an adjustable amount relating to a higher capacity than the AF 212 is calculated for the power electronics device 211.

[0118] The system information also includes target information regarding the target for which temperature and / or humidity adjustment is to be performed by the HPS21. In this case, it is possible to calculate an adjustable amount suitable for the target to be subjected to temperature and humidity adjustment by the HPS 21, compared to a case where the adjustable amount calculation unit 305 calculates the adjustable amount without using the target information.

[0119] Also, from another perspective, the HPS 21 of this embodiment calculates the amount of adjustment possible when the HPS 21 is adjusting the temperature and / or humidity, based on the system information. In this case, instruction server 40 can determine a current value to be supplied by HPS 21 in order to adjust the apparent power in the electric wires of power system 10, based on the adjustable amount calculated by HPS 21. Therefore, when HPS 21 is adjusting temperature and humidity, adjustment of the apparent power in the electric wires of power system 10 by HPS 21 can be realized.

[0120] In addition, the configurations described above are not limited to the above embodiments, and can be modified without departing from the spirit of the invention. In other words, it is understood that various modifications of the form and details are possible without departing from the spirit and scope of the claims. The present invention is not limited to the above-described configurations, and some of the configurations described above may be omitted, or other functions may be added to the configurations described above.
