[0024] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In this specification and the drawings, substantially the same components are designated by the same reference numerals, and redundant description may be omitted.

[0025] A management system SY according to a first embodiment will be described with reference to FIGS.

[0026] The management system SY is a system for managing multiple solar power generation facilities. As shown in Fig. 1, the management system SY includes a first solar power generation facility a1, an a1 server (first device) 1, a second solar power generation facility b1, a b1 server (second device) 2, a power seller terminal (user terminal) 3, a monitor terminal (user terminal) 4, and a management server 5.

[0030] The second solar power generation facility b1 is a facility that generates power using sunlight. As shown in Fig. 3, the second solar power generation facility b1 includes a solar panel b11, a power conditioner b12, a power receiving and transforming facility b13, a meter b14, and a logger b15. The elements b11 to b15 that make up the power generation facility b1 will be described later.

[0031] In the following description, the second photovoltaic power generation facility b1 will be referred to as the "power generation facility b1."

[0032] The b1 server 2 is a device that processes information transmitted from the power generation facility b1. The b1 server 2 is connected to a network NW. The b1 server 2 is connected to a logger b15 of the power generation facility b1 via the network NW.

[0033] The power seller terminal 3 is a communication terminal used by power seller (user) Y. Power seller Y owns power generation facilities a1 and b1. Power seller Y is an entity that operates a business (hereinafter referred to as "the service") of selling electricity generated by both power generation facilities a1 and b1 to electric power companies.

[0034] The electricity seller terminal 3 is connected to the network NW. The electricity seller terminal 3 is connected to the management server 5 via an ID (account) that identifies the electricity seller Y. The electricity seller Y uses the management system SY to carry out the work related to the service in question.

[0035] The monitor terminal 4 is a communication terminal used by a monitor (user) Z. The monitor Z is a person who runs a business of monitoring the states of the power generation facilities a1 and b1.

[0036] The monitor terminal 4 is connected to the network NW. The monitor terminal 4 is connected to the management server 5 via an ID (account) that identifies the monitor Z. The monitor Z uses the management system SY to monitor the status of the power generation facilities a1 and b1. For example, if a problem occurs with the power generation facility a1, the monitor Z notifies the power seller Y and dispatches personnel to the power generation facility a1 to resolve the problem.

[0037] In the following description, the power seller Y and the monitor Z will be referred to as "users", and the power seller terminal 3 and the monitor terminal 4 will be referred to as "user terminals" as appropriate.

[0038] The management server 5 is an information processing device that manages the power generation facilities a1 and b1. The management server 5 is a device that processes information relating to the status of the power generation facilities a1 and b1 in particular. The management server 5 functions as a platform required to operate the management system SY.

[0039] Programs for performing various processes are installed in the management server 5. The management server 5 is connected to a network NW. The management server 5 transmits information about the status of the power generation facilities a1 and b1 to a user terminal via the network NW.

[0040] Next, the solar panel a11, the power conditioner a12, the power receiving and transforming equipment a13, the meter a14, and the logger a15 will be described with reference to FIG.

[0041] The solar panel a11 is a device that generates direct current (DC) by utilizing solar energy. The solar panel a11 outputs the generated DC to the power conditioner a12. In the following description, the power conditioner a12 will be referred to as "power conditioner a12" where appropriate.

[0042] The inverter a12 is a device that converts direct current into alternating current (AC). When the inverter a12 receives the direct current output from the solar panel a11, it converts the input direct current into alternating current. The inverter a12 outputs the converted alternating current to the power receiving and transforming equipment a13. The AC voltage output from the inverter a12 to the power receiving and transforming equipment a13 is a low voltage, such as 500V or 200V.

[0043] The power receiving and transforming equipment a13 is, for example, a cubicle-type high-voltage power receiving and transforming equipment. The power receiving and transforming equipment a13 is equipment that boosts low voltage to high voltage. When the power receiving and transforming equipment a13 receives the AC output from the power conditioner a12, it boosts the voltage of the input AC from low voltage to high voltage.

[0044] The meter a14 is a device that measures the amount of electric power. The meter a14 measures the amount of AC electric power output from the power receiving and transforming equipment a13 to the electric power company. The power receiving and transforming equipment a13 transmits the AC power that has been boosted to a high voltage to the electric power company via the electric wire a16 of the high-voltage system.

[0045] In the first embodiment, the power generation facility a1 is configured to limit the amount of AC power output per hour from the inverter a12 to the power receiving and transforming facility a13 to 49.5 kWh. In other words, the maximum amount of power that the power generation facility a1 can generate per hour is 49.5 kWh, i.e., the maximum instantaneous power generation power of the power generation facility a1 is 49.5 kW. In the following description, the maximum amount of power that the power generation facility a1 can generate per hour is referred to as the "power generation capacity of the power generation facility a1."

[0046] The logger a15 is a device that stores various information. The logger a15 stores information on the amount of AC power output from the inverter a12 to the power receiving and transforming equipment a13, as well as other information. The logger a15 transmits the information on the amount of AC power stored in the logger a15 to the a1 server 1 via the network NW.

[0047] In the first embodiment, the logger a15 is configured to store information on the amount of AC power output from the power conditioner a12 to the substation equipment a13 and transmit this stored information to the a1 server 1, but this configuration is not limited to this, and the logger a15 may also be configured to store information on the amount of AC power measured by the meter a14 and transmit this stored information to the a1 server 1.

[0048] Next, the solar panel b11, the power conditioner b12, the power receiving and transforming equipment b13, the meter b14, and the logger b15 will be described with reference to FIG.

[0049] The solar panel b11, power conditioner b12, substation equipment b13, and meter b14 have the same configuration as the solar panel a11, power conditioner a12, substation equipment a13, and meter a14, respectively, and therefore their description will be omitted.

[0050] In the first embodiment, power generation equipment b1 is configured to limit the amount of AC power output per hour from power conditioner b12 to power receiving and transforming equipment b13 to 49.5 kWh. In other words, the maximum amount of power that power generation equipment b1 can generate per hour is 49.5 kWh, i.e., the maximum instantaneous power generation power of power generation equipment b1 is 49.5 kW. In the following description, the maximum amount of power that power generation equipment b1 can generate per hour is referred to as the "power generation capacity of power generation equipment b1."

[0051] In the first embodiment, the power generation capacities of the power generation facilities a1 and b1 are each 49.5 kWh, but this is not limited to this configuration and may be, for example, 20 kWh each, or 600 kWh each. Also, in the first embodiment, the power generation capacity of the power generation facility a1 and the power generation capacity of the power generation facility b1 are the same, 49.5 kWh, but this is not limited to this configuration and the power generation capacities of the power generation facility a1 and the power generation facility b1 may be different from each other, for example, the power generation capacity of the power generation facility a1 is 49.5 kWh and the power generation capacity of the power generation facility b1 is 600 kWh.

[0052] The logger b15 is a device that stores various information. The logger b15 stores information on the amount of AC power output from the inverter b12 to the power receiving and transforming equipment b13, as well as other information. The logger b15 transmits the information on the amount of AC power stored in the logger b15 to the b1 server 2 via the network NW.

[0053] In the first embodiment, the logger b15 is configured to store information on the amount of AC power output from the inverter b12 to the power receiving and transforming equipment b13 and transmit this stored information to the b1 server 2. However, the present invention is not limited to this configuration, and the logger b15 may be configured to store information on the amount of AC power measured by the meter b14 and transmit this stored information to the b1 server 2.

[0054] In the first embodiment, the a1 server 1 is configured to transmit the information on the amount of AC power transmitted from the logger a15 to the management server 5 without a request from the management server 5. On the other hand, the b1 server 2 is configured to transmit the information on the amount of AC power transmitted from the logger b15 to the management server 5 in response to a request from the management server 5. In other words, the management server 5 is configured to acquire the first power generation amount information from the a1 server 1 without requesting the first power generation amount information from the a1 server 1 (first device) that stores information on the amount of AC power (first power generation amount information) indicating the amount of power generated by the solar power generation facility a1, and to acquire the second power generation amount information from the b1 server 1 by requesting the second power generation amount information from the b1 server 2 (second device) that stores information on the amount of AC power (second power generation amount information) indicating the amount of power generated by the solar power generation facility b1.

[0055] In the first embodiment, the photovoltaic power generation facilities a1 and b1 may be configured not to include the power receiving and transforming facilities a13 and b14, respectively.

[0056] Next, the hardware configuration of the a1 server 1 will be described with reference to FIG.

[0057] The a1 server 1 includes a storage unit 10 and a control unit 20. The storage unit 10 and the control unit 20 are electrically connected via a communication bus (not shown).

[0058] The storage unit 10 includes a ROM, a RAM, and a hard disk (not shown). The storage unit 10 stores programs executed by the control unit 20. The storage unit 10 stores various information transmitted from the logger a15. The various information transmitted from the logger a15 to the a1 server 1 includes information on the amount of AC power output from the inverter a12 to the power receiving and transforming equipment a13, i.e., information on the amount of power generated by the power generation equipment a1.

[0059] In the following description, the information on the amount of AC power transmitted from the logger a15 to the a1 server 1, that is, the information indicating the amount of power generated by the power generation facility a1 (first power generation amount information), will be referred to as "a1 power generation amount data."

[0060] The control unit 20 includes a CPU, a ROM, and a RAM (not shown). The control unit 20 reads out programs stored in the storage unit 10 and loads them into the RAM, thereby executing various processes.

[0061] The control unit 20 includes an extraction unit 21 and a transmission unit 22 .

[0062] When the control unit 20 receives the a1 power generation amount data transmitted from the logger a15, the control unit 20 stores the received a1 power generation amount data in the storage unit 10.

[0063] FIG. 5 shows an example of a1 power generation amount data stored in the storage unit 10 by the control unit 20 from 5:00 (5:00 AM) to just before 6:00 (6:00 AM) on a certain day.

[0064] 5, the a1 power generation amount data stored in the storage unit 10 by the control unit 20 is "0 (kWh)" for the time period from 5:00 to just before 5:10, "0.2 (kWh)" for the time period from 5:10 to just before 5:20, "0.8 (kWh)" for the time period from 5:20 to just before 5:30, "1.0 (kWh)" for the time period from 5:30 to just before 5:40, "0.5 (kWh)" for the time period from 5:40 to just before 5:50, and "0.5 (kWh)" for the time period from 5:50 to just before 6:00. In other words, the amount of power generated by the power generation facility a1 from 5:00 to 6:00 is "3.0 (kWh)."

[0065] In the following description, information on the time period corresponding to the a1 power generation amount data stored in the storage unit 10 will be referred to as "a1 time period data."

[0066] The extraction unit 21 accesses the storage unit 10 at intervals of 10 minutes, and extracts the a1 power generation amount data for the most recent 10 minutes and the a1 time period data corresponding to this a1 power generation amount data from the a1 power generation amount data stored in the storage unit 10. Note that the a1 power generation amount data for the most recent 10 minutes extracted by the extraction unit 21 at intervals of 10 minutes is a1 power generation amount data that the extraction unit 21 has not yet extracted.

[0067] In the specific example of FIG. 5, when 5:10 has passed, the memory unit 10 stores only the a1 power generation amount data "0" corresponding to the a1 time period data "5:00-5:10," so the extraction unit 21 extracts the a1 power generation amount data "0" when 5:10 has passed.

[0068] 5, for example, when 5:20 has passed, the storage unit 10 stores "0" corresponding to the a1 time slot data "5:00-5:10" and "0.2" corresponding to the a1 time slot data "5:10-5:20." However, the "0" corresponding to the a1 time slot data "5:00-5:10" is data that has already been extracted by the extraction unit 21 when 5:10 has passed. Therefore, the extraction unit 21 extracts the a1 power generation amount data "0.2" when 5:20 has passed.

[0069] 5, for example, when 6:00 has passed, the storage unit 10 stores "0", "0.2", "0.8", "1.0", "0.5", and "0.5", but the data "0", "0.2", "0.8", "1.0", and "0.5" from 5:00 to before 5:50 have already been extracted by the extraction unit 21 when 5:50 has passed. Therefore, the extraction unit 21 extracts the a1 power generation amount data "0.5" when 6:00 has passed.

[0070] The transmitting unit 22 transmits the extracted data to the management server 5 every time the extracting unit 21 extracts the a1 power generation amount data and the a1 time period data.

[0071] For example, in FIG. 5, when 5:30 has passed, the extraction unit 21 extracts the a1 power generation data “0.8” stored in the memory unit 10 for the last 10 minutes and the a1 time zone data “5:20-5:30” corresponding to this “0.8”, and transmits these “0.8” and “5:20-5:30” to the management server 5.

[0072] Thus, in the first embodiment, the a1 server 1 is configured to transmit to the management server 5, at predetermined time intervals (regular cycles) (10 minutes) without being requested by the management server 5, the a1 power generation amount data (first power generation amount information) stored in the memory unit 10 during the predetermined time (10 minutes) from the first hour (e.g., 5:20) to just before the second hour (e.g., 5:30) has elapsed, and the a1 time zone data (first time information, e.g., "5:20-5:30") corresponding to this a1 power generation amount data.

[0073] In the first embodiment, the control unit 20 is configured to extract the a1 power generation data stored in the memory unit 10 during the 10-minute period (time period) from the first hour (e.g., 5:00) to just before the second hour (e.g., 5:10) has elapsed, once the second hour (e.g., 5:10) has elapsed, and to transmit the extracted a1 power generation data to the management server 5 at 10-minute intervals. However, the configuration is not limited to this. The control unit 20 may be configured to extract the a1 power generation amount data stored in the memory unit 10 for, for example, a 5-minute period (time zone) from the first hour (e.g., 5:00) until the second hour (e.g., 5:05) has elapsed, and transmit the extracted a1 power generation amount data to the management server 5 at 5-minute intervals, or to extract the a1 power generation amount data stored in the memory unit 10 for, for example, a 1-minute period (time zone) from the first hour (e.g., 5:00) until the second hour (e.g., 5:01) has elapsed, and transmit the extracted a1 power generation amount data to the management server 5 at 1-minute intervals, when the second hour (e.g., 5:01) has elapsed.

[0074] 5, for ease of explanation, the example of the a1 power generation amount data stored in the memory unit 10 by the control unit 20 is shown in 10-minute increments, such as the 10 minutes from 5:00 to just before 5:10, the 10 minutes from 5:10 to just before 5:20, the 10 minutes from 5:20 to just before 5:30, etc. However, the data may be shown in 1-minute increments, such as the 1 minute from 5:00 to just before 5:01, the 1 minute from 5:01 to just before 5:02, the 1 minute from 5:03 to just before 5:04, etc., or may be shown in 2-minute or 5-minute increments. Furthermore, each time the control unit 40 stores a1 power generation amount data, the hour, minute, and second at which the data was stored and the a1 power generation amount data stored in the memory unit 10 up to that hour, minute, and second may be displayed.

[0075] Next, the hardware configuration of the b1 server 2 will be described with reference to FIG.

[0076] The b1 server 2 includes a storage unit 30 and a control unit 40. The storage unit 30 and the control unit 40 are electrically connected via a communication bus (not shown).

[0077] The storage unit 30 includes a ROM, a RAM, and a hard disk (not shown). The storage unit 30 stores programs executed by the control unit 40. The storage unit 30 stores various information transmitted from the logger b15. The various information transmitted from the logger b15 to the b1 server 2 includes information on the amount of AC power output from the inverter b12 to the power receiving and transforming equipment b13, i.e., information on the amount of power generated by the power generation equipment b1.

[0078] In the following description, the information on the amount of AC power transmitted from the logger b15 to the b1 server 2, that is, the information indicating the amount of power generated by the power generation facility b1 (second power generation amount information), will be referred to as "b1 power generation amount data."

[0079] The control unit 40 includes a CPU, a ROM, and a RAM (not shown). The control unit 40 reads out programs stored in the storage unit 30 and loads them into the RAM to execute various processes.

[0080] The control unit 40 includes an extraction unit 41 and a transmission unit 42 .

[0081] When the control unit 40 receives the b1 power generation amount data transmitted from the logger b15, the control unit 40 stores the received b1 power generation amount data in the storage unit 30.

[0082] FIG. 7 shows an example of the b1 power generation amount data stored in the storage unit 30 by the control unit 40 from 5:00 to just before 6:00 on a certain day.

[0083] 7, the b1 power generation amount data stored in the memory unit 30 by the control unit 40 is "0.1 (kWh)" for the time period from 5:00 to just before 5:20, "0.8 (kWh)" for the time period from 5:00 to just before 5:40, and "1.0 (kWh)" for the time period from 5:00 to just before 6:00. In other words, the amount of power generated by the power generation facility a1 from 5:00 to 6:00 is "1.0 (kWh)."

[0084] In the following description, information on the time period corresponding to the b1 power generation amount data stored in the storage unit 30 will be referred to as "b1 time period data."

[0085] Unlike the extraction unit 21 of the a1 server 1, the extraction unit 41 extracts the b1 power generation amount data stored in the storage unit 30 based on a request from the management server 5. In other words, the management server 5 is configured to acquire the b1 power generation amount data from the b1 server 1 by requesting the b1 power generation amount data (second power generation amount information) indicating the amount of power generated by the second solar power generation facility b1 from the b1 server 2 that stores the b1 power generation amount data.

[0086] Specifically, the extraction unit 41 accesses the storage unit 30 based on a request from the management server 5, and extracts predetermined b1 power generation amount data and b1 time zone data corresponding to the predetermined b1 power generation amount data from the b1 power generation amount data stored in the storage unit 30. Note that the predetermined b1 power generation amount data extracted by the extraction unit 41 is b1 power generation amount data that the extraction unit 41 has not yet extracted.

[0087] Specifically, the management server 5 accesses the b1 server 2 at intervals of 20 minutes and requests the b1 server 2 to extract predetermined b1 power generation amount data from the b1 power generation amount data stored in the memory unit 30 and b1 time zone data corresponding to the predetermined b1 power generation amount data. Based on this request, the extraction unit 41 is configured to extract the requested b1 power generation amount data and b1 time zone data.

[0088] In the specific example of FIG. 7, when 5:20 has passed, the memory unit 30 stores only the b1 power generation data "0.1" corresponding to the b1 time period data "5:00-5:20", so the extraction unit 41 extracts the b1 power generation data "0.1" when 5:20 has passed.

[0089] In the specific example of FIG. 7, when 5:40 has passed, the storage unit 30 stores the b1 power generation amount data "0.1" corresponding to the b1 time period data "5:00-5:20" and the b1 power generation amount data "0.8" corresponding to the b1 time period data "5:00-5:40." However, since the former "0.1" has already been extracted by the extraction unit 41 when 5:20 has passed, the extraction unit 41 extracts the latter b1 power generation amount data "0.8" when 5:40 has passed.

[0090] In the specific example of Figure 7, when 6:00 passes, only the b1 time zone data "5:00-6:00" (1.0) from 5:00 to just before 6:00) has not been extracted, so the extraction unit 41 extracts this b1 power generation data "1.0" when 6:00 passes.

[0091] The transmitting unit 42 transmits the extracted data to the management server 5 every time the extracting unit 41 extracts the b1 power generation amount data and the b1 time period data.

[0092] For example, in FIG. 7, when 6:00 has passed, the extraction unit 41 extracts the b1 power generation amount data "1.0" stored in the memory unit 30 between 5:00 and before 6:00 and the b1 time zone data "5:00-6:00" corresponding to this "1.0", and the transmission unit 42 transmits these "1.0" and "5:00-6:00" to the management server 5.

[0093] As described above, in the first embodiment, the b1 server 1 stores information on the amount of AC power (b1 power generation data) transmitted from the logger b15 in the memory unit 30, and the management server 5 is configured to request the b1 server 1 to transmit (extract) the b1 power generation data at predetermined time intervals (20 minutes), and based on the request for transmission of the b1 power generation data from the management server 5, the b1 server 1 is configured to transmit to the management server 5 the b1 power generation data cumulatively stored in the memory unit 30 from the first hour (e.g., 5:00) until just before the second hour (e.g., 5:40) has elapsed, and the b1 time zone data corresponding to this b1 power generation data.

[0094] For ease of explanation, FIG. 7 shows examples of the b1 power generation amount data stored in the memory unit 30 by the control unit 40, with the b1 power generation amount data stored in the memory unit 30 being summarized every 20 minutes, such as the 20 minutes from 5:00 to just before 5:20, the 40 minutes from 5:00 to just before 5:40, and the 60 minutes from 5:00 to just before 6:00. However, the b1 power generation amount data stored in the memory unit 30 may be summarized every minute, such as the 1 minute from 5:00 to just before 5:01, the 2 minutes from 5:00 to just before 5:02, and the 3 minutes from 5:00 to just before 5:03, or may be summarized every 5 or 10 minutes. Furthermore, each time the control unit 40 stores the b1 power generation amount data, the hour, minute, and second at which the data is stored may be displayed together with the b1 power generation amount data stored in the storage unit 30 up to that time, minute, and second.

[0095] Next, the hardware configuration of the management server 5 will be described with reference to FIG.

[0096] The management server 5 includes a storage unit 50 and a control unit 60. The storage unit 50 and the control unit 60 are electrically connected via a communication bus (not shown).

[0097] The storage unit 50 includes a ROM, a RAM, and a hard disk (not shown). The storage unit 50 stores a program executed by the control unit 60.

[0098] The storage unit 50 stores various information. The various information includes information on the amount of AC power (a1 power generation amount data) acquired from the a1 server 1 without making a request to the a1 server 1, information on the time period corresponding to the a1 power generation amount data (a1 time period data), information on the amount of AC power (b1 power generation amount data) acquired from the b1 server 2 by making a request to the b1 server 2, information on the time period corresponding to the b1 power generation amount data (b1 time period data), information on the amount of predicted power generation (expected value) described later, and other information.

[0099] The control unit 60 includes a CPU, a ROM, and a RAM (not shown). The control unit 60 reads out programs stored in the storage unit 50 and loads them into the RAM to execute various processes.

[0100] The control unit 60 includes a request unit 61 , a conversion unit 62 , a prediction unit 63 , a generation unit 64 , and a transmission unit 65 .

[0101] The request unit 61 requests the b1 server 2 at regular intervals to transmit the b1 power generation amount data to the management server 5. Specifically, the request unit 61 accesses the b1 server 2 every 20 minutes and requests the b1 server 2 (storage unit 30) to transmit predetermined b1 power generation amount data stored therein (b1 power generation amount data that has not been transmitted to the management server 5).

[0102] As described above, the b1 server 2 is configured to transmit the b1 power generation amount data to the management server 5 based on a request from the request unit 61 (management server 5). On the other hand, the a1 server 1 is configured to transmit the a1 power generation amount data to the management server 5 without being based on a request from the request unit 61 (management server 5). In other words, the management server 5 does not request the a1 server 1 to transmit the a1 power generation amount data to the management server 5.

[0103] In the first embodiment, the request unit 61 is configured to request the b1 server 2 (storage unit 30) to transmit the b1 power generation amount data stored in the b1 server 2 (storage unit 30) for a 20-minute period (time period) from a first hour (e.g., 5:00) to just before a second hour (e.g., 5:20) has elapsed to the management server 5 when the second hour (e.g., 5:20) has elapsed. In other words, the management server 5 is configured to acquire the b1 power generation amount data stored in the b1 server 2 at 20-minute intervals. However, the configuration is not limited to this, and the management server 5 may be configured to acquire the b1 power generation amount data stored in the b1 server 2 at 10-minute, 5-minute, or 1-minute intervals.

[0104] The control unit 60 stores the power generation amount data (a1 power generation amount data, b1 power generation amount data) received by the management server 5 and the time zone data (a1 time zone data, b1 time zone data) corresponding to this power generation amount data in the memory unit 50.

[0105] The conversion unit 62 converts the power generation amount data stored in the storage unit 50 and the time period data corresponding to this power generation amount data into a predetermined format.

[0106] Here, the a1 server 1 is configured to start storing the a1 power generation amount data for a certain day at 5:00, and at 5:10, 10 minutes after the start time, transmit the a1 power generation amount data stored in the memory unit 10 for those 10 minutes to the management server 5, and at 5:20, 10 minutes after 5:10, transmit the a1 power generation amount data stored in the memory unit 10 for those 10 minutes to the management server 5, and at 19:00, 10 minutes after 18:50, transmit the a1 power generation amount data stored in the memory unit 10 for those 10 minutes to the management server 5, and finish storing the data at 18:00. In other words, the a1 server 1 is configured to transmit the a1 power generation amount data stored for 13 hours (780 minutes) from 5:00 to 18:00 on a certain day to the management server 5 at regular intervals (every 10 minutes).

[0107] On the other hand, for the b1 power generation amount data for a certain day, the b1 server 2 starts storing the data at 5:00, and at 5:20, 20 minutes after the start time, it transmits the b1 power generation amount data stored in the memory unit 30 during those 20 minutes to the management server 5; at 5:40, 20 minutes after 5:20, in other words, when 40 minutes have passed since the start time, it transmits the b1 power generation amount data stored in the memory unit 30 during those 40 minutes to the management server 5; and at 18:00, 20 minutes after 17:40, in other words, when 780 minutes (13 hours) have passed since the start time of 5:00, it transmits the b1 power generation amount data stored in the memory unit 30 during those 780 minutes to the management server 5, and ends storing them at 18:00. In other words, the b1 server 1 is configured to transmit the sum of the b1 power generation amount data stored in the memory unit 30 to the management server 5 at a fixed period (every 20 minutes).

[0108] In this way, the a1 server 1 transmits the a1 power generation amount data for the most recent 10 minutes to the management server 5, while the b1 server 1 transmits the sum of the b1 power generation amount data stored from the start of storing the b1 power generation amount data until a certain point in time to the management server 5. That is, the two power generation amount data acquired by the management server 5 have different time zone formats. In other words, the time information (first time information) corresponding to the a1 power generation amount data (first power generation amount information) acquired by the management server 5 and the time information (second time information) corresponding to the b1 power generation amount data (second power generation amount information) acquired by the management server 5 have different lengths. For this reason, if these two power generation amount data are provided in their original format to the electricity seller Y, who owns both power generation facilities a1 and b1, and the monitor Z, who monitors both power generation facilities a1 and b1, it is difficult for the two users to understand the provided power generation amount data. As a result, for example, they may overlook a problem with the power generation facility a1 or miss an opportunity to improve the power generation amount of the power generation facility b1.

[0109] Therefore, in the first embodiment, the a1 power generation amount data and the b1 power generation amount data, which have different time slot formats, are converted (unified) so that the time slot formats are the same, and the converted a1 power generation amount data and the converted b1 power generation amount data are provided to users (power seller Y and monitor Z). In short, the a1 power generation amount data and the b1 power generation amount data are converted so that the a1 time slot data (first time information) corresponding to the a1 power generation amount data (first power generation amount information) and the b1 time slot data (second time information) corresponding to the b1 power generation amount data (second power generation amount information) have the same length, and the converted data are provided to users.

[0110] Specifically, the a1 power generation amount data and the b1 power generation amount data are converted so that the a1 power generation amount data and the b1 power generation amount data before conversion become power generation amount data per hour (specific unit time). In other words, the a1 time period data and the b1 time period data are converted so that the a1 time period data and the b1 time period data have a length equivalent to one hour.

[0111] In the following explanation, converting (unifying) the time zone formats so that the time zone formats for the a1 power generation amount data and the b1 power generation amount data are the same is referred to as "standardization." For ease of explanation, the standardized (converted) a1 power generation amount data is referred to as "a1 standard data," the standardized (converted) b1 power generation amount data is referred to as "b1 standard data," and the time zone data corresponding to the a1 standard data and the b1 standard data is referred to as "standard time zone data."

[0112] 9(a) is an explanatory diagram for explaining the standardization of the a1 power generation amount data. As shown in the figure, the conversion unit 62 converts the six pre-conversion a1 power generation amount data "0," "0.2," "0.8," "1.0," "0.5," and "0.5" stored in the storage unit 50 into the a1 standard data "3.0" per hour (specific unit time).

[0113] 9(b) is an explanatory diagram for explaining the standardization of the b1 power generation amount data. As shown in the figure, the conversion unit 62 converts the three pre-conversion b1 power generation amount data "0.1," "0.8," and "1.0" stored in the storage unit 50 into the b1 standard data "1.0" per hour (specific unit time).

[0114] In the first embodiment, the a1 power generation amount data and the b1 power generation amount data are converted to be power generation amount data per hour, but the present invention is not limited to this configuration. On the premise that the power generation amount data is easy for the user to understand, the a1 power generation amount data and the b1 power generation amount data may be converted to be power generation amount data per 30 minutes, for example. That is, when converting at least one of the a1 power generation amount data and the b1 power generation amount data so that the a1 time period data (first time information) and the b1 time period data (second time information) have the same length, the management server 5 may convert at least one of the a1 power generation amount data and the b1 power generation amount data so that both the a1 power generation amount data and the b1 power generation amount data become power generation amount data (power generation amount information) per predetermined 30 minutes (specific unit time).

[0115] In the first embodiment, the a1 server 1 is configured to start storing the a1 power generation amount data at 5:00 and finish at 18:00, but this is not limiting, and the storage of the a1 power generation amount data may be configured to start at 6:00 and finish at 19:00, for example, depending on the location of the power generation facility a1 corresponding to the a1 server 1. Similarly, the storage of the b1 power generation amount data may be configured to start at 4:00 and finish at 19:00, for example, depending on the location of the power generation facility b1 corresponding to the b1 server 2.

[0116] In the first embodiment, the a1 server 1 transmits the a1 power generation amount data for the most recent 10 minutes to the management server 5, while the b1 server 1 transmits the b1 power generation amount data, which is the total sum from the start time of storage until a predetermined time is reached, to the management server 5, and both of these power generation amount data are converted into power generation amount data per hour. However, for example, in this configuration, if the a1 server 1 is configured to transmit the a1 power generation amount data for the most recent 60 minutes to the management server 5 every 60 minutes, the a1 power generation amount data (first power generation amount information) is power generation amount data (power generation amount information) per hour (specific unit time), so there is no need to convert the a1 power generation amount data, and only the b1 power generation amount data needs to be changed into power generation amount data per hour. That is, when the a1 time zone data (first time information) corresponding to the a1 power generation amount data (first power generation amount information) transmitted from the a1 server (first device) 1 to the management server 5 and the b1 time zone data (second time information) corresponding to the b1 power generation amount data (second power generation amount information) transmitted from the b1 server (second device) 2 to the management server 5 are of different lengths, it is sufficient to convert at least one of the a1 power generation amount data and the b1 power generation amount data so that the a1 time zone data and the b1 time zone data have the same length (for example, 1 hour).

[0117] The prediction unit 63 predicts, for each photovoltaic power generation facility, an expected value for the amount of power generated per hour (specific unit time) at the photovoltaic power generation facility.

[0118] In the following explanation, the expected value (first expected value) for the amount of power generation per hour (specific unit time) at power generation equipment a1 will be referred to as the "a1 expected value," and the expected value (second expected value) for the amount of power generation per hour at power generation equipment b1 will be referred to as the "b1 expected value."

[0119] The prediction unit 63 predicts the expected value based on information on solar radiation per hour at the location of the solar power generation facility, the power generation capacity of the solar power generation facility, the installation conditions of the solar panels (for example, the installation angle of the solar panels relative to the angle of sunlight irradiation), and other information.

[0120] Solar radiation information at the location of a solar power generation facility is based on satellite information transmitted from satellites orbiting the Earth (such as cloud conditions at the latitude and longitude corresponding to the location), solar radiation, fog occurrence information, and other information.

[0121] The prediction unit 63 starts predicting the expected value at 5:00 on a given day and finishes predicting the expected value at 18:00. Specifically, at 6:00, one hour after 5:00, the prediction unit 63 calculates the expected value and stores the calculated expected value in the storage unit 50, at 7:00, one hour after 6:00, the prediction unit 63 calculates the expected value and stores the calculated expected value in the storage unit 50, and at 18:00, one hour after 17:00, the prediction unit 63 calculates the expected value and stores the calculated expected value in the storage unit 50, thereby completing the calculation of the expected value for a given day.

[0122] 10 is a diagram showing an example of the a1 standard data and a1 expected value corresponding to the standard time zone data for a certain day stored in the storage unit 50. As shown in the figure, for example, the standard time zone data "5:00-6:00" corresponds to the a1 standard data "3" and the a1 expected value "5." This indicates that during the one hour from 5:00 to 6:00, the a1 expected value for the power generation facility a1 was 5 (kWh), but the power generated by the power generation facility a1 was actually 3 (kWh), which is 2 (kWh) less than that.

[0123] As described above, the prediction unit 63 predicts the expected value based on the power generation capacity of the photovoltaic power generation facilities, etc. Here, the power generation capacity of power generation facility a1 is 49.5 (kWh), and the power generation capacity of power generation facility b1 is 49.5 (kWh). Therefore, the upper limit of the a1 expected value calculated by the prediction unit 63 is 49.5 (kWh), and the upper limit of the b1 expected value calculated by the prediction unit 63 is 49.5 (kWh).

[0124] If the power generation capacity of the solar power generation facility is, for example, "20 (kWh)" or "600 (kWh)", the upper limit of the expected value calculated by the prediction unit 63 will be "20 (kWh)" or "600 (kWh)".

[0125] In the first embodiment, the management server 5 is configured to include a prediction unit 63, and the prediction unit 63 calculates the expected value, but this configuration is not limited to this.The management server 5 may not be configured to include a prediction unit 63, and an information processing device other than the management server 5 may calculate the expected value, and the management server 5 may store this calculated expected value in the memory unit 30.

[0126] The generating unit 64 generates a power generation amount graph representing the amount of power generated by each photovoltaic power generation facility. The generating unit 64 generates the power generation amount graph based on a request from a user.

[0127] In the following description, the power generation amount graph corresponding to the power generation amount of the power generation facility a1 is referred to as "a1 graph", and the power generation amount graph corresponding to the power generation amount of the power generation facility b1 is referred to as "b1 graph".

[0128] To generate the a1 graph, the generation unit 64 extracts the standard time zone data and the corresponding a1 standard data and a1 expected value from the storage unit 50, and generates the a1 graph based on this extracted information.

[0129] To generate the b1 graph, the generation unit 64 extracts the standard time zone data and the corresponding b1 standard data and b1 expected value from the storage unit 50, and generates the b1 graph based on this extracted information.

[0130] In the first embodiment, the management server 5 is configured to start managing the amount of power generated by the photovoltaic power generation facility at 5:00 and end at 18:00 on the same day, and to generate a power generation amount graph for the amount of power generated from the management start time to the management end time. However, this configuration is not limited to this, and for example, depending on the location of the photovoltaic power generation facility, the management server 5 may be configured to start managing the amount of power generated by the photovoltaic power generation facility at 4:00 and end at 19:00 on the same day, and to generate a power generation amount graph for the amount of power generated from the management start time to the management end time.

[0131] In the first embodiment, the management server 5 (generation unit 64) is configured to generate a power generation amount graph based on a request from a user, but this configuration is not limited to this. The management server 5 may be configured to generate a power generation amount graph at specific intervals such as 30 minutes or 1 hour, store the generated power generation amount graph in the memory unit 50, and provide the user with the latest power generation amount graph stored in the memory unit 50 when the user requests to view the power generation amount graph.

[0132] FIG. 11 is an example of an a1 graph generated based on the information shown in FIG. 10. As shown in the figure, the a1 graph G1 is represented by coordinates along the horizontal and vertical axes. The horizontal axis of the a1 graph G1 shows times from 5:00 to 19:00 at equal hourly intervals, and the vertical axis shows the amount of power generated, ranging from 0 (kWh) to 55 (kWh). The vertical axis shows "49.5 (kWh)," which indicates the power generation capacity of the power generation facility a1. In the a1 graph G1, the a1 standard data is represented by the length of a bar-shaped line segment, and the a1 expected value is represented by a broken line connecting the points representing the value with line segments. The a1 graph G1 also includes a capacity line L1. The capacity line L1 indicates the power generation capacity of the power generation facility a1, and as shown in the figure, it shows "49.5 (kWh)."

[0133] Figure 12 is an enlarged view of a portion of Figure 11. This figure shows that the amount of power generated by power generation facility a1 during one hour (specific unit time) from 5:00 to 6:00 (a1 standard data corresponding to the standard time slot data "5:00-6:00") was 3 (kWh), and that the expected value of power generation facility a1 during that one hour from 5:00 to 6:00 (a1 expected value corresponding to the standard time slot data "5:00-6:00") was 5 (kWh).

[0134] Figure 13 is an enlarged view of a part of Figure 11. This figure shows that the amount of power generated by power generation facility a1 during one hour (specific unit time) from 12:00 to 13:00 (a1 standard data corresponding to the standard time zone data "12:00-13:00") has reached the power generation capacity of power generation facility a1, and also shows that the expected value of power generation facility a1 during the one hour period from 12:00 to 13:00 has reached the power generation capacity of power generation facility a1.

[0135] 14 is a diagram showing an example of b1 standard data and b1 expected values ​​corresponding to standard time zone data for a certain day stored in the storage unit 50. This diagram has the same configuration as FIG. 10, and therefore detailed description thereof will be omitted.

[0136] Fig. 15 is an example of a b1 graph generated based on the information shown in Fig. 14. Fig. 15 has the same configuration as Fig. 14, so a detailed description thereof will be omitted. However, like the a1 graph, the b1 graph G2 includes a capacity line L2 indicating the power generation capacity of the power generation facility b1, and as shown in the figure, the capacity line L2 indicates "49.5 (kWh)." The figure shows that the b1 standard data and the b1 expected value do not reach the power generation capacity of the power generation facility b1 in any of the standard time slots.

[0137] In the first embodiment, the a1 server 1 transmits the a1 power generation amount data stored in the storage unit 10 for 10 minutes (hereinafter referred to as "10-minute a1 power generation amount data") to the management server 5 at 10-minute intervals, and the management server 5 converts six 10-minute a1 power generation amount data into hourly power generation amount data (a1 standard data) and generates an a1 graph based on the a1 standard data. However, in this configuration, the a1 server 1 may transmit the 10-minute a1 power generation amount data to the management server 5 every 120 minutes, or every 90 minutes. For example, when transmitting the 10-minute a1 power generation amount data to the management server 5 every 120 minutes, the management server 5 receives 12 10-minute a1 power generation amount data from the a1 server 1 every 120 minutes, converts the received 12 10-minute a1 power generation amount data into two a1 standard data, and generates an a1 graph based on the a1 standard data.

[0138] Based on a request from the power seller terminal 3 (power seller Y), the transmission unit 65 transmits information about the power generation amount graph generated by the generation unit 64 to the power seller terminal 3. When the power seller terminal 3 receives the information about the power generation amount graph transmitted from the transmission unit 65, it displays the received power generation amount graph in the display area of ​​the power seller terminal 3.

[0139] Based on a request from the monitor terminal 4 (monitor Z), the transmission unit 65 transmits the power generation amount graph generated by the generation unit 64 to the monitor terminal 4. When the monitor terminal 4 receives the information on the power generation amount graph transmitted from the transmission unit 65, the monitor terminal 4 displays the received power generation amount graph in the display area of ​​the monitor terminal 4.

[0140] Next, a part of the processing in the management system SY will be explained.

[0141] FIG. 16 is a flowchart showing part of the processing carried out between the a1 server 1 and the management server 5.

[0142] As shown in Figure 16, the a1 server 1 transmits the a1 power generation amount data stored in the memory unit 10 for the last 10 minutes and the corresponding a1 time zone data to the management server 5 (step S1), and when the management server 5 receives the a1 power generation amount data and the a1 time zone data transmitted in step S1 (step S2), it stores the received data in the memory unit 50 (step S3).

[0143] FIG. 17 is a flowchart showing part of the processing carried out between the management server 5 and the b1 server 2.

[0144] 17, the management server 5 requests the b1 server 2 to transmit the b1 power generation amount data (step S10), and upon receiving the request from the management server 5, the b1 server 2 extracts the b1 power generation amount data and the corresponding b1 time zone data stored in the storage unit 30 (step S11), and transmits the extracted data to the management server 5 (step S12). Upon receiving the b1 power generation amount data and the b1 time zone data transmitted in step S12 (step S13), the management server 5 stores the received data in the storage unit 50 (step S14).

[0145] FIG. 18 is a flowchart showing an example of a process (a1 power generation amount data conversion process) in which the management server 5 (converter 62) converts the a1 power generation amount data into a1 standard data.

[0146] (Step S21) The conversion unit 62 determines whether all of the a1 power generation amount data stored in the memory unit 50 from the management start time to the management end time today has been converted into a1 standard data, and if all of the conversion has been completed, ends the a1 power generation amount data conversion process, and if all of the conversion has not been completed, proceeds to the next process.

[0147] In the first embodiment, the management system SY is configured to manage the status of the solar power generation equipment from 5:00 (5:00 AM) to 18:00 (6:00 PM) in a day, with the management start time being 5:00 and the management end time being 18:00.

[0148] (Step S22) The conversion unit 62 determines whether or not N hours (where N is a positive integer) have passed since the management start time, and if so, proceeds to the next process, and if not, returns to before step S22.

[0149] For example, when 5:30 has passed, it is determined that one hour (N=1) has not yet passed since the management start time of 5:00, and when 6:00 has passed, it is determined that one hour (N=1) has passed since the management start time of 5:00.

[0150] (Steps S23 to S25) The conversion unit 62 extracts the a1 power generation amount data stored in the memory unit 50 for the most recent hour (S23), converts the extracted a1 power generation amount data into a1 standard data (S24), stores the converted a1 standard data in the memory unit 50 (S25), and terminates the a1 power generation amount data conversion process.

[0151] For example, as shown in FIG. 9(a), when 6:00 has passed, the conversion unit 62 accesses the memory unit 50 and extracts six a1 power generation data values ​​"0", "0.2", "0.8", "1.0", "0.5", and "0.5" stored in the memory unit 50 for the last hour (between 5:00 and 6:00), and converts the sum of these six extracted a1 power generation data values ​​"3.0" into a1 standard data corresponding to the standard time zone data from 5:00 to 6:00.

[0152] Although illustrations and detailed explanations are omitted, the management server 5 (conversion unit 62) performs a process (b1 power generation data conversion process) to convert the b1 power generation data stored in the memory unit 50 between today's management start time (5:00) and management end time (18:00) into b1 standard data, similar to the a1 power generation data conversion process.

[0153] 9(b), when 6:00 has passed, the converter 62 accesses the storage unit 50, extracts the b1 power generation data stored in the storage unit 50 for the last hour (between 5:00 and 6:00), and converts the extracted b1 power generation data into b1 standard data. In the example shown in the figure, the three b1 power generation data "0.1," "0.8," and "1.0" extracted when 6:00 has passed are converted into the b1 standard data "1.0."

[0154] FIG. 19 is a flowchart showing part of the processing carried out between the power seller terminal 3 and the management server 5.

[0155] 19, the electricity seller terminal 3 requests the management server 5 to view the a1 graph (step S30), and upon receiving the view request from the electricity seller terminal 3, the management server 5 executes a process to generate the a1 graph (hereinafter referred to as the "a1 graph generation process") (step S40), and transmits (data of) the a1 graph generated in the same step to the electricity seller terminal 3 (step S31). Upon receiving the a1 graph transmitted from the management server 5 (step S32), the electricity seller terminal 3 displays the a1 graph in the display area of ​​the electricity seller terminal 3 (step S33).

[0156] The process performed when the supervisor terminal 4 requests viewing of the a1 graph is the same as that shown in FIG. 19, and therefore the description and drawings thereof will be omitted.

[0157] FIG. 20 is a flowchart showing the a1 graph generation process.

[0158] (Step S41) First, the generation unit 64 accesses the memory unit 50 and extracts the a1 standard data stored in the memory unit 50 from the management start time (5:00) to the current time (the time when the viewing request was made from the electricity seller terminal 3), the a1 expected value corresponding to this a1 standard data, and the standard time zone data corresponding to this a1 standard data and a1 expected value.

[0159] For example, if a viewing request is made from the electricity seller terminal 3 at 6:05, as shown in Figure 10, the generation unit 64 extracts the a1 standard data "3" stored in the memory unit 50 from 5:00 to 6:05, the a1 expected value "5" corresponding to this "3", and the standard time zone data "5:00-6:00" corresponding to both of these data, and generates an a1 graph from 5:00 to 6:00 based on this extracted data (information) (see Figure 12).

[0160] For example, if a viewing request is made from the electricity seller terminal 3 at 13:20, as shown in Figure 10, the generation unit 64 extracts the a1 standard data "3", "10", ... "49.5" stored in the memory unit 50 from 5:00 to 13:20, the corresponding a1 expected values ​​"5", "15", ... "49.5", and the standard time zone data "5:00-13:00" corresponding to these data, and generates an a1 graph from 5:00 to 13:00 based on this extracted data (information) (see Figure 13).

[0161] For example, if a viewing request is made from the electricity seller terminal 3 at 20:30 after the management end time, as shown in Figure 10, the generation unit 64 extracts the a1 standard data "3", "10", "49.5", "17", and "2" stored in the memory unit 50 between 5:00 and 18:00, the corresponding a1 expected values ​​"5", "15", "49.5", "17", and "4", and the standard time zone data "5:00-18:00" corresponding to these data, and generates an a1 graph from 5:00 to 18:00 (a certain day) based on this extracted data (information) (see Figure 11).

[0162] Although illustrations and detailed explanations are omitted, the management server 5 (generation unit 64), similar to the a1 graph generation process, accesses the memory unit 50 in response to a viewing request from a user (power seller Y, monitor Z) and executes a b1 graph generation process to generate a b1 graph based on the b1 standard data stored in the memory unit 50 between the management start time (5:00) and the current time (the time when the viewing request was made from the user terminal), the corresponding b1 expected value, and the corresponding standard time zone data.

[0163] 21 is a diagram showing an example of screen G displayed in the display area of ​​a user terminal (power seller terminal 3, monitor terminal 4). As shown in the figure, screen G is a list screen that displays a1 graph G1 and b1 graph G2 in a list. Although detailed explanation and illustration are omitted, for example, when a user terminal connects to the management server 5 via an ID (account) that identifies the user, screen G is displayed in the display area of ​​the user terminal immediately after the connection.

[0164] In the first embodiment, the screen G is configured to be displayed in the display area of ​​the user terminal immediately after connecting to the management server 5, but this configuration is not limited to this. For example, a screen dedicated to the user (electricity seller Y, monitor Z) may be provided, a button for displaying screen G may be placed on that dedicated screen, and screen G may be displayed in the display area of ​​the user terminal by selecting that button with an input device such as a mouse.

[0165] As described above, in the first embodiment, the management server 5 is configured to acquire the a1 power generation amount data without making a request to the a1 server 1, acquire the b1 power generation amount data by making a request to the b1 server 2, generate the a1 graph and the b1 graph based on both power generation amount data, and provide the generated power generation graph to the user terminal. Therefore, even if a single power seller Y owns multiple solar power generation facilities that acquire power generation amount data using different methods, the power seller Y can grasp the amount of power generated by each of these multiple solar power generation facilities via the management system SY. Similarly, when a monitor Z monitors multiple solar power generation facilities that acquire power generation amount data using different methods, the monitor Z can monitor the status of these multiple solar power generation facilities (the operating status of the solar power generation facilities) by using only a single management system SY, thereby reducing the workload.

[0166] In the first embodiment, a screen G displaying a list of the a1 graph and the b1 graph is configured to be displayed in the display area of ​​the user terminal, so that the amount of power generated by multiple solar power generation facilities can be grasped at a glance.

[0167] In particular, the a1 power generation data sent to management server 5 is data stored by a1 server 1 over a 10-minute period, whereas the b1 power generation data sent to management server 5 is the sum of data stored by b1 server 2 from the time it started storing b1 power generation data until a certain point in time. Therefore, if these are graphed in their original format, it is difficult for users (power seller Y, monitor Z) to grasp the amount of power generated by each solar power generation facility.

[0168] In this regard, in the first embodiment, the a1 power generation data and the b1 power generation data are converted so that both become predetermined hourly power generation data, and the a1 graph and the b1 graph are generated based on the converted power generation data (a1 standard data, b1 standard data), and these generated power generation graphs are provided to the user (user terminal) in a list format, so that the power generation amounts produced by each solar power generation facility can be compared and understood at a glance.

[0169] In the first embodiment, when generating a power generation graph corresponding to a plurality of solar power generation facilities, the management server 5 is configured to place capacity lines indicating the power generation capacity of each solar power generation facility on the power generation graph, so that the power generation amount of the solar power generation facility relative to the power generation capacity of the solar power generation facility can be easily grasped visually.

[0170] In the first embodiment, the expected value for the amount of power generation per hour at each solar power generation facility is predicted, and a power generation graph showing these expected values ​​is generated, so that the user can easily understand the operating status of the solar power generation facility.

[0171] Here, the amount of power generated by a photovoltaic power generation facility fluctuates depending on the weather (meteorological conditions), but if the amount of power generated does not increase even if the weather improves, that is, if the amount of power generated is lower than the expected value calculated based on solar radiation information, etc., it is predicted that some kind of trouble has occurred in the photovoltaic power generation facility, such as dirt, damage, or aging of the solar panels. In this regard, in the first embodiment, the expected value is displayed on the power generation graph, making it possible to detect and solve the trouble early and reduce the damage.

[0172] In the first embodiment, the expected value is calculated taking into account the power generation capacity of the photovoltaic power generation facility, and the calculated expected value is displayed on the power generation graph, so that the expected value will not exceed the power generation capacity of the photovoltaic power generation facility. In other words, in the first embodiment, the power generation graph is generated so as not to reflect information (expected value) that exceeds the power generation capacity of the photovoltaic power generation facility. Therefore, information unnecessary for the present service is not provided to the user, and misunderstanding by the user can be prevented.

[0173] In the first embodiment, it goes without saying that the management system SY may be configured to manage other photovoltaic power generation facilities in addition to the power generation facilities a1 and b1. In this case, too, a power generation amount graph is generated for each photovoltaic power generation facility based on standardized power generation amount data, and the generated power generation amount graphs are provided to the user in a list. For example, the management system SY is configured to manage the photovoltaic power generation facility c1 in addition to the power generation facilities a1 and b1, and the management server 5 acquires the c1 power generation amount data without making a request to a c1 server that stores the c1 power generation amount data indicating the amount of power generated by the photovoltaic power generation facility c1 (hereinafter referred to as a "first method"), or acquires the c1 power generation amount data by making a request to the c1 server (hereinafter referred to as a "second method"), and generates a power generation amount graph based on the acquired c1 power generation amount data.

[0174] In the above configuration, for example, the management system SY may be configured to manage the solar power generation facility d1 in addition to the power generation facilities a1, b1, and c1, and in this configuration, the management server 50 may acquire d1 power generation amount data indicating the amount of power generated by the solar power generation facility d1 by a third method other than the first and second methods, and generate a power generation amount graph based on the acquired d1 power generation amount data. As the third method, for example, an operator stores a paper or electronic medium showing the d1 power generation amount data in the memory unit 50 of the management server 5.

[0175] In this way, the multiple solar power generation facilities include power generation facilities that have different methods for obtaining power generation data by the management server 5, and the management server 5 standardizes the power generation data corresponding to each of the multiple solar power generation facilities, generates multiple power generation graphs based on this standardized data, transmits the generated multiple power generation graphs to the user terminal, and the user terminal displays the multiple power generation graphs in a list in the display area of ​​the user terminal.

[0176] Next, a second embodiment will be described. The second embodiment differs from the first embodiment in that the management system SY does not include the a1 server 1. Only the configuration of the second embodiment that differs from the first embodiment will be described below.

[0177] 22 is a diagram schematically illustrating a management system according to the second embodiment. The management system SY according to the second embodiment includes a power generation facility a1, a power generation facility b1, a b1 server 2, a power seller terminal 3, a monitor terminal 4, and a management server 5.

[0178] In the second embodiment, the logger a15 of the power generation facility a1 is configured to transmit first power generation amount information (a1 power generation amount data) indicating the amount of power generated by the power generation facility a1 to the management server 5 via the network NW.

[0179] Specifically, the power generation facility a1 (logger a15) transmits the a1 power generation amount data stored in the logger a15 to the management server 5 without being based on a request from the management server 5. In other words, the management server 5 acquires the a1 power generation amount data from the power generation facility a1 without requesting the a1 power generation amount data from the power generation facility a1 (logger a15).

[0180] The power generation equipment a1 (logger a15) of the second embodiment, similar to the a1 server 1 of the first embodiment, transmits to the management server 5, at intervals (regular periods) of a predetermined time (for example, 10 minutes), the a1 power generation amount data stored in the logger a15 between the first hour (for example, 5:20) and before the second hour (for example, 5:30) has elapsed, and the time period data (first time information, for example, "5:20-5:30") corresponding to this a1 power generation amount data.

[0181] In the second embodiment, similarly to the first embodiment, the b1 server 2 (second device) transmits the b1 power generation amount data stored in the b1 server 2 to the management server 5 in response to a request from the management server 5. That is, the management server 5 obtains the b1 power generation amount data from the b1 server 2 by making a request to the b1 server 2.

[0182] In the second embodiment, the power generation facility a1 (logger a15) may transmit the a1 power generation amount data to the management server 5 based on a request from the management server 5, and the b1 server 2 may transmit the b1 power generation amount data to the management server 5 without based on a request from the management server 5.

[0183] Next, a third embodiment will be described. The third embodiment differs from the first embodiment in that the management system SY does not include the a1 server 1 and the b1 server 2. In the following, only the configuration of the third embodiment that differs from the first and second embodiments will be described.

[0184] 23 is a diagram schematically illustrating a management system according to the third embodiment. The management system SY according to the third embodiment includes a power generation facility a1, a power generation facility b1, a power seller terminal 3, a monitor terminal 4, and a management server 5.

[0185] In the third embodiment, the logger a15 of the power generation equipment a1 is configured to transmit first power generation amount information (a1 power generation amount data) indicating the amount of power generated by the power generation equipment a1 to the management server 5 via the network NW, and the logger b15 of the power generation equipment b1 is configured to transmit second power generation amount information (b1 power generation amount data) indicating the amount of power generated by the power generation equipment b1 to the management server 5 via the network NW.

[0186] Specifically, the power generation facility a1 (logger a15) transmits the a1 power generation amount data to the management server 5 without being based on a request from the management server 5, and the power generation facility b1 (logger b15) transmits the b1 power generation amount data to the management server 5 based on a request from the management server 5. In other words, the management server 5 acquires the a1 power generation amount data from the power generation facility a1 without requesting the a1 power generation amount data from the power generation facility a1 (logger a15), and acquires the b1 power generation amount data from the power generation facility b1 by requesting the b1 power generation amount data from the power generation facility b1 (logger b15).

[0187] It goes without saying that in the third embodiment, the power generation facility a1 (logger a15) may transmit the a1 power generation amount data to the management server 5 based on a request from the management server 5, and the power generation facility b1 (logger b15) may transmit the b1 power generation amount data to the management server 5 without based on a request from the management server 5.

[0188] Next, a fourth embodiment will be described. The fourth embodiment differs from the first to third embodiments in the method of calculating the expected value. Only the configuration of the fourth embodiment that differs from the first to third embodiments will be described below.

[0189] 24 is a diagram schematically illustrating a management system according to the fourth embodiment. The management system according to the fourth embodiment includes a solar power generation facility a1, a solar power generation facility a2, a solar power generation facility b1, a solar power generation facility b2, and a solar power generation facility b3.

[0190] Also, although not shown in the figures, the management system of the fourth embodiment includes a device (a1 server 1) that processes information etc. transmitted from solar power generation facility a1, a device (hereinafter referred to as the "a2 server") that processes information etc. transmitted from solar power generation facility a2, a device (b1 server 2) that processes information etc. transmitted from solar power generation facility b2 (hereinafter referred to as the "b2 server"), a device (hereinafter referred to as the "b3 server") that processes information etc. transmitted from solar power generation facility b3, a power seller terminal 3, a monitor terminal 4, and a management server 5.

[0191] The a2 server is a device that stores power generation data indicating the amount of power generated by the solar power generation facility a2. The b2 server is a device that stores power generation data indicating the amount of power generated by the solar power generation facility b2. The b3 server is a device that stores power generation data indicating the amount of power generated by the solar power generation facility b3.

[0192] An electricity seller Y owns solar power generation facilities a1, a2, b1, b2, and b3. A monitor Z monitors the status of the solar power generation facilities a1, a2, b1, b2, and b3.

[0193] As shown in Fig. 24, area A (first area) is an area that includes solar power generation facilities a1 and a2, and area B (second area) is an area that includes solar power generation facilities b1, b2, and b3.

[0194] The management server 5 is an information processing device that manages the photovoltaic power generation facilities a1, a2, b1, b2, and b3. As in the first embodiment, the management server 5 acquires the a1 power generation amount data from the a1 server 1 by a first method (without requesting the a1 power generation amount data from the a1 server 1), and acquires the b1 power generation amount data from the b1 server 2 by a second method (requesting the b1 power generation amount data from the b1 server 2).

[0195] In the fourth embodiment, the management server 5 acquires the power generation data stored in each server from the a2 server, the b2 server, and the b3 server using one of the first, second, and third methods (for example, a method in which an operator stores a paper or electronic medium showing the power generation data in the memory unit of the management server 5).

[0196] In the fourth embodiment, the prediction unit 63 is configured to use solar radiation information at a specific point within an area as the standard for that area, and predict an expected value for each solar power generation facility included in the area based on the standard solar radiation information (hereinafter referred to as "standard solar radiation information"), the power generation capacity of the solar power generation facility, the installation conditions of the solar panels (for example, the installation angle of the solar panels relative to the irradiation angle of sunlight), and other information.

[0197] For example, area A includes two solar power generation facilities a1 and a2, and the solar radiation information at one specific point A1 (first specific point) within area A is adopted as the standard solar radiation information for area A, and based on this standard solar radiation information, the prediction unit 63 predicts the expected values ​​of each of the solar power generation facilities a1 and a2.

[0198] One specific point A1 may be, for example, a point that is approximately the same distance from the two solar power generation facilities a1 and a2, or may be, for example, the location of either of the two solar power generation facilities a1 and a2, or may be, for example, the center point of area A that is circular with a radius of X meters (for example, X=1000), or may be, for example, the center point of area A that is square with each side being X meters (for example, X=500), and is set appropriately depending on the environment of area A, etc.

[0199] For example, area B includes three solar power generation facilities b1, b2, and b3, and one solar radiation information at one specific point B1 (second specific point) within area B is adopted as the standard solar radiation information for area B, and based on this standard solar radiation information, the prediction unit 63 predicts the expected value of each of the solar power generation facilities b1 to b3.

[0200] One specific point B1 may be, for example, a point that is approximately the same distance from the three solar power generation facilities b1 to b3, or may be, for example, the location of any of the three solar power generation facilities b1 to b3, or may be, for example, the center point of area B that is circular with a radius of X meters (for example, X=1000), or may be, for example, the center point of area B that is square with each side being X meters (for example, X=500), and is set appropriately depending on the environment of area B, etc.

[0201] As in the first embodiment, the standard solar radiation information at the specific points A1 and B1 is based on satellite information transmitted from satellites orbiting the Earth, the amount of solar radiation, fog occurrence information, and other information.

[0202] As described above, the fourth embodiment differs from the first to third embodiments in that it uses standard irradiance information for one specific point within an area and predicts the expected value for the amount of power generated per hour at each photovoltaic power generation facility included in the area based on the standard irradiance information, eliminating the need for irradiance information for each photovoltaic power generation facility. This reduces the burden of obtaining and calculating irradiance information for each photovoltaic power generation facility.

[0203] In the fourth embodiment, the management system may be configured not to include at least one of the a1 server 1, a2 server, b1 server 2, b2 server, and b3 server. For example, in a configuration that does not include only the b3 server, the solar power generation facility b3 is configured to transmit power generation amount information indicating the amount of power generated by the solar power generation facility b3 to the management server 5 via the network NW.

[0204] It goes without saying that the first to fourth embodiments may be appropriately combined. For example, the management system may include a first solar power generation facility, a second solar power generation facility, a third solar power generation facility, a third device that stores third power generation amount information indicating the amount of power generated by the third solar power generation facility, a fourth solar power generation facility, a fourth device that stores fourth power generation amount information indicating the amount of power generated by the fourth solar power generation facility, a user terminal, and a management server, in which the first solar power generation facility transmits first power generation amount information indicating the amount of power generated by the first solar power generation facility to the management server without being based on a request from the management server, the second solar power generation facility transmits second power generation amount information indicating the amount of power generated by the second solar power generation facility to the management server based on a request from the management server, and the third device transmits the third power generation amount information to the management server based on a request from the management server.
