Background Art
[0002] Currently, for the widespread use of sunlight, wind power, and other non-fossil energy sources (hereinafter referred to as renewable energy) that can be permanently used as energy sources, in order to ensure power supply when large-scale power generation facilities such as nuclear power plants and thermal power plants stop operating due to natural disasters such as earthquakes and typhoons, the widespread use of renewable energy power generation mechanisms using renewable energy is desired. And, in order to prevent long-term power outages when power transmission lines and the like are damaged due to natural disasters such as earthquakes and typhoons, it is preferable that the distance between the renewable energy power generation mechanism and the demand area that receives power is short, as in the case where a renewable energy power generation mechanism is installed in a building such as a detached house. And, when there is damage to power transmission lines and the like due to natural disasters such as earthquakes and typhoons, in order to prevent long-term power outages, it is preferable that the distance between the renewable energy power generation mechanism and the demand area that receives power is short, as in the case where a renewable energy power generation mechanism is installed in a building such as a detached house. [[ID=;28]] As a renewable energy power generation mechanism that can be relatively easily used in buildings such as detached houses, solar power generation equipment can be cited.
[0003] As described above, from the viewpoints of the widespread use of renewable energy and the on-site consumption of electricity, the widespread use of solar power generation equipment in buildings such as detached houses is desired, and for further widespread use, installation in rental real estate having a plurality of facilities such as apartment houses is also demanded.

[0005] [Patent Document 1] Patent No. 6824600 [Overview of the project] [Problems that the invention aims to solve]
[0006] By the way, the rent for an apartment in a multi-unit building depends on the distance from the building to public transportation and the number of people living there. In addition to conditions common to the rooms in the apartment building, such as the number of years since the building was constructed, other factors such as size and floor level are also considered. It is determined by the conditions of each room, such as the number and location. Furthermore, rooms that are difficult to rent out are given lower rent than other rooms, thus attracting residents. While it is common to try to secure this, they are adding unprecedented conditions that will lead to raising rents. If you agree, you can raise the rent. Therefore, we considered unprecedented conditions that could lead to an increase in rent, including working from home. With the spread of remote work, the number of electrical appliances used in living spaces has increased, and also, As usage time is increasing, having access to inexpensive and stable electricity is important for living spaces. It has been found that this could be an important factor when considering whether to borrow it. And to enable the use of renewable energy for that inexpensive and stable power supply. A system that can support the management of those who own rental properties, with as little new electrical wiring work as possible. By making it possible to introduce renewable energy generation without having to do so, rental properties can be equipped with renewable energy power generation.

Modes for Carrying Out the Invention
[0015] [First Embodiment] The following describes the management support system for rental properties according to the first embodiment of the present invention (hereinafter simply referred to as "the management support system for rental properties 1"). The management support system (referred to as "Management Support System 1") will be explained with reference to Figures 1 and 2. In this embodiment, the management support system 1 is a complex having multiple rooms 71 and shared facilities 72 Used in the 70 series of combined housing. In Figure 1, the solid lines connecting each block indicate the flow of power, and the dashed lines connecting each block indicate the flow of power. This indicates the flow of control signals or communicated information. The dashed lines indicate communication between various devices. This is done by a communication network 61 for interconnection.
[0016] The management support system 1 of this embodiment sets the rent lower than that of other rooms 71. For this particular room 71, the electricity generated by the solar power generation equipment will be used with priority over other rooms 71. By making it available, the rent for specific room 71A is increased to secure residents. This is intended to support that. Furthermore, while prioritizing use in specific rooms 71, the entire apartment complex 70 as a whole... This is intended to increase the utilization rate of renewable energy. As will be described later, Management Support System 1 acts between the owners of the 70 apartment buildings and the power company. This system is implemented when a contract is in place to purchase electricity for the entire apartment building in a single unit. First, I will explain apartment building 70, and then I will explain management support system 1.
[0017] [Apartment housing 70] As shown in Figure 1, the apartment building 70 consists of living rooms 71, common facilities 72, and living rooms 71 which will be described later. It also includes a power supply mechanism 80 for supplying power to the loads of the shared facilities 72. The power supply mechanism 80 is connected to the power transmission network 100. In the apartment building 70, electricity is supplied to each room 71 through a bulk power purchase system. The electric power company has a contract to receive electricity in bulk for the entire 70 apartment buildings (bulk electricity supply contract), and the power grid We have agreements with power companies that supply electricity via 100. In this embodiment, the bulk power receiving business consumes the electricity necessary for the apartment building 70 to receive high-voltage bulk power. Therefore, bulk power reception will be conducted at a power level less than the power required for high-voltage bulk power reception (for example, 50kW). Therefore, power companies have entered into bulk low-voltage power receiving agreements with each other. The bulk electricity purchasing company is either the owner of the 70 apartment buildings or has entrusted the management of the 70 apartment buildings to that owner. This could be the administrator or the owner of the renewable energy generation organization 20 described later. These persons may be singular or plural. Also, natural persons or legal persons. That's fine.
[0018] Multiple units of living space 71 are provided in the apartment building 70. As shown in Figure 1, the living room 71 can be equipped with a facility load 73 that consumes electricity. . Facility load 73 is equipment that consumes power in the living room 71, for example, equipment used in the living room 71 Examples of appliances used include air conditioners, microwave ovens, refrigerators, televisions, and routers.
[0019] As shown in Figure 1, room 71 is divided into designated room 71A and rooms not designated as designated room 71A. It can be divided into general living room 71B and another room. Furthermore, if there is no need to distinguish between specific rooms 71A and general rooms 71B, simply refer to them as rooms 71 and It is sometimes referred to as such.
[0020] In this embodiment, the control device 13, which will be described later, selects a specific room 71A for each room 71. Various selection criteria are recorded. Selection criteria include conditions such as difficulty in securing a suitable resident for that particular room 71. It can be done. Conditions that make it difficult to secure residents include, for example, the continuously occurring first choice conditions and The second condition applies only to specific times, scheduled days of the week, or periods when specific temperatures and humidity levels are met. It can be listed. The first selection criteria include, for example, the size and location of the living rooms 71, and the structure of the apartment building 70. This includes situations where it becomes difficult to secure residents. A second selection criterion is, for example, that the temperature and humidity at the location of apartment building 70 exceed predetermined values. Conditions that make it difficult to secure residents due to seasonal changes, or poor sunlight Examples include situations where it is difficult to secure residents for specific time slots, such as when there are specific time periods. ru. Furthermore, if there is no need to distinguish between the first and second selection criteria, they are simply referred to as selection criteria. It can happen.
[0021] Room 71 is selected based on the number of selection conditions that are met among the set selection conditions, It is selected as a designated room 71A. Then, the selected specific rooms 71A form a group of specific rooms 71C. Specifically, referring to Figure 2, how is a general room 71B selected from a specific room 71A? Next, we will explain how specific room group 71C is formed. As shown in Figure 2, the apartment building 70 has living rooms 71a to d on the first floor and living rooms on the second floor. 71e~h are provided.
[0022] First, let's explain the case where room 71A is selected based solely on the first selection criterion. In this embodiment, the specific living room 71A is selected in descending order of the number of applicable first selection conditions. . The first selection criterion is that room 71, located on the first floor, is the first choice from a security standpoint. Selection condition a, and from a privacy standpoint, room 7 is not a so-called corner room but has rooms 71 on both sides. Two conditions are set for the first selection condition b attached to 1. Then, rooms 71a to d located on the first floor were recorded as meeting the first selection condition a. Rooms 71b, 71c, 71f, and 71g, which have rooms 71 on both sides, meet the first selection condition b. It is recorded that... Therefore, as shown in Figure 2, rooms 71b and 71c meet the two first selection criteria. However, it is preferentially selected as designated room 71A, and together with room 71b and room 71c, it forms designated room group 71 C is formed.
[0023] Furthermore, the number of rooms 71 constituting the specific room group 71C is the number of regenerative rooms in this embodiment, which will be described later. In the energy supply adjustment method, the predicted total electricity demand D1 for a specific group of rooms 71C is Possible supply amount C1 from supply and demand adjustment device 11 and forecast from renewable energy generation mechanism 20 It is adjusted to be approximately equal to the total supply quantity S1. Specifically, the predicted total electricity demand D1 for the specific room group 71C is determined by the first supply and demand adjustment device 11. The sum of their possible supply C1 and the predicted supply S1 from the renewable energy generation organization 20 If there are few, a room 71 that meets one of the first selection criteria will also be selected as a specific room 71A. (See Figure 4 S1-6). On the other hand, the predicted total electricity demand D1 for the specific room group 71C is available from the first supply and demand adjustment device 11. If the supply amount C1 is greater than the sum of the predicted supply amount S1 from the renewable energy generation organization 20 In some cases, the number of specific rooms 71A will be reduced, and in some cases rooms 71b and rooms Room 71c is no longer selected as a designated room 71A, and the number of rooms selected as designated rooms 71A is now 0. It can happen. The second selection criterion, along with the first selection criterion described later, is used to select specific room 71A. The same applies in that case.
[0024] Next, the second selection criterion is used along with the first selection criterion to select specific room 71A. Let me explain the situation. When using the second selection criterion along with the first selection criterion, and when using only the first selection criterion, Similarly, the number of rooms 71 that constitute the specific room group 71C is the number of regenerative rooms in this embodiment, which will be described later. In the energy supply adjustment method, the predicted total electricity demand D1 for the specific room group 71C is first The possible supply amount C1 from the supply and demand adjustment device 11 and the predicted supply from the renewable energy generation mechanism 20 It is adjusted to be approximately equal to the total of the feed amounts S1. In this embodiment, the second selection condition is a corner room where humidity control is necessary during the rainy season. Selection condition a is set. When the humidity level at the location of apartment building 70 exceeds a specified level, the corner rooms on the first floor, 71a,7 1d, 71e, and 71h satisfy the second selection condition. In that case, in the renewable energy supply adjustment method of this embodiment described later, When increasing the number of rooms 71A, rooms 71a and 71d that also satisfy one of the first selection conditions are first Room 71A is given priority over rooms 71f and 71g, which only meet one selection criterion. It will be done. In other words, the predicted total electricity demand D1 for the specific room group 71C, consisting of rooms 71b and 71c, The available supply amount C1 from the first supply and demand adjustment device 11 and the available supply amount from the renewable energy generation mechanism 20 If it is less than the sum of the measured supply amounts S1, the predicted total electricity demand D1 for the specific room group 71C is , the possible supply amount C1 from the first supply and demand adjustment device 11 and from the renewable energy generation mechanism 20 First, rooms 71a and 71d are designated as specific rooms 71A, so that they are approximately equal to the total predicted supply S1. After being selected, rooms 71f and 71g are then selected as specific rooms 71A.
[0025] Furthermore, as a second selection criterion, the top floor, where indoor temperatures tend to be high in the summer, is the second choice Selection condition b is set. When the temperature at the location of apartment building 70 exceeds a specified level, the living rooms on the top floor 71e~71h will be second This will satisfy selection condition b. In that case, in the renewable energy supply adjustment method of this embodiment described later, When increasing the number of rooms 71A, rooms 71f and 71g that also satisfy one of the first selection conditions are first Room 71A is given priority over rooms 71a and 71d, which only meet one selection criterion. It will be done. In other words, the predicted total electricity demand D1 for the specific room group 71C, consisting of rooms 71b and 71c, The available supply amount C1 from the first supply and demand adjustment device 11 and the available supply amount from the renewable energy generation mechanism 20 If it is less than the sum of the measured supply amounts S1, the predicted total electricity demand D1 for the specific room group 71C is , the possible supply amount C1 from the first supply and demand adjustment device 11 and from the renewable energy generation mechanism 20 First, rooms 71f and 71g are designated as specific rooms 71A, so that they are approximately equal to the total predicted supply S1. After being selected, rooms 71a and 71d are then selected as specific room 71A.
[0026] As described above, when the second selection criterion is used along with the first selection criterion, the specified room group 7 Room 1C may have different priority in being selected as a specific room 71A depending on the time of day and season.
[0027] In this embodiment, the specific room 71A is selected preferentially from the number of applicable first selection conditions. However, priorities are set for the first selection criteria according to their importance, and according to those priorities... Room 71A may be selected. The second selection criterion, like the first selection criterion, can be prioritized according to its importance.
[0028] Furthermore, additional conditions can be added to the first selection criteria as needed. For example, if buildings are constructed around apartment building 70 If the construction would spoil the landscape, that can be added as a primary selection criterion. The second selection criterion can be added as appropriate, just like the first selection criterion.
[0029] Furthermore, the selection criteria for a specific room 71A include the condition that it is difficult to secure an occupant. I have listed some examples to explain, but the selection criteria are not limited to these. Depending on the requests of prospective tenants and residents... Various selection criteria may be set. For example, in recent years, in order to promote the decarbonization of the electricity used in companies' production activities, employee housing There is a growing movement to collect decarbonized power sources and their environmental value. If there are prospective tenants who are attracted to Room 71, which can create more value in terms of lifestyle and environment, The first selection condition may be set so that the room 71 becomes a designated room 71A. Additionally, for residents who wish to work from home, the daytime days on which they will work from home will be a second selection criterion. It's okay to do so.
[0030] The shared facility 72 can be equipped with a facility load 73 that consumes electricity, as shown in Figure 1. ru. The facility load 73 of the shared facility 72 is equipment that consumes power in the shared facility 72, for example. Examples include emergency equipment (such as fire alarms), streetlights, and septic tank blower power supplies. It can be done. Furthermore, the facility load 73 of the specified room 71A and the facility load 73 of the general room 71B are as described above. The combined facility load 73 of the shared facilities 72 is sometimes referred to as the apartment building load 70a.
[0031] As shown in Figure 1, the power supply mechanism 80 includes a higher-level metering device 81 and a centralized power receiving panel 82. It includes an upper distribution board 83, a lower metering device 84, and a lower distribution board 85.
[0032] The upper meter device 81 is generally referred to as the master meter, as shown in Figure 1. It is installed between the power transmission network 100 and the centralized power receiving panel 82. The upper meter device 81 is a meter device with a verification that is verified in accordance with the Measurement Law, and the validity period of the verification is It belongs to the area. A smart meter may be used as the higher-level metering device 81.
[0033] The upper meter device 81 measures the amount of electricity purchased by the apartment building 70 from the power grid 100, i.e., the collective The total amount of electricity received by the entire residential complex 70 from the power grid 100, E1, is detected. Furthermore, the upper meter device 81 is used when the apartment building 70 is powered by the renewable energy generation organization 20. The amount of electricity supplied, E2, to be sold to the power grid 100 is detected. The amount of electricity supplied E2 is the electricity output from the renewable energy generation organization 20 to the apartment building. If the received power is greater than the load of 70A, the surplus power is reverse-flowed to the power grid 100. This is the amount of surplus electricity. The higher-level metering device 81 then controls the detected power received E1 and power supplied E2. Output to device 13. Specifically, the upper-level metering device 81 measures any unit of time such as 1 second, 30 minutes, or 1 hour (T The power received E1 and power supplied E2 for each cycle are output to the control device 13.
[0034] The upper metering device 81 is connected to the power company with which the owners of the apartment building 70 have a bulk electricity supply contract. Therefore, the received power amount E1 and supplied power amount E2 are managed and output, and used for calculating electricity charges, etc. It can be used.
[0035] As shown in Figure 1, the bulk power receiving panel 82 is connected to the higher-level metering device 81 and receives low-voltage bulk power. It is used to receive power from the power transmission network 100. The centralized power receiving panel 82 supplies power from the power transmission network 100 to the upstream distribution panel 83.
[0036] As shown in Figure 1, the upper distribution panel 83 is located downstream from the centralized power receiving panel 82. The power line branches into two at a junction, and it is connected to one of them. The other branch will be discussed later. It is connected to the bio-energy generation mechanism 20 via the measuring device 12.
[0037] The lower meter device 84 is what is commonly called a sub-meter, and the lower meter device Item 84 is a meter device with a certification that is verified in accordance with the Measurement Law, and is within the validity period of the certification. . The lower-level metering device 84 may be a smart meter.
[0038] As shown in Figure 1, the lower metering device 84 is installed in each living room 71 and in the shared facilities 72. The amount of electricity E5 received by each facility load 73 from the power transmission network 100 is measured, and the measurement A fixed amount of power is output to the control device 13. Specifically, the lower meter device 84 measures any unit of time such as 1 second, 30 minutes, or 1 hour (T The amount of power received E5 for each cycle is output to the control device 13. The lower-level metering device 84 may be managed by the bulk power receiving business operator.
[0039] As shown in Figure 1, the lower distribution boards 85 are installed in each living room 71 and in the shared facilities 72. .
[0040] [Renewable Energy Generation Organization 20] As shown in Figure 1, the renewable energy power generation mechanism 20 includes a solar power generation facility 21 and a power - Conditioner (Power Conditioner System: PCS) 22 It has, and In this embodiment, the renewable energy power generation mechanism 20 is installed outside the premises of the apartment complex 70. It is being done. The solar power generation equipment 21 has solar modules, which are not shown in the illustration.
[0041] The power conditioner 22 controls the charging and discharging from the solar power generation equipment 21 and the first supply and demand cycle described later. This device controls the charging and discharging of the first storage battery that constitutes the adjustment device 11.
[0042] The power conditioner 22 converts the DC power generated by the solar power generation equipment 21 into AC power. It includes an inverter for generating power and a state detection unit. The status detection unit monitors and acquires the operating status of the solar power generation equipment 21 and the first supply and demand adjustment device 11. The operation log is output to the control device 13. The operation log includes the power generation status of the solar power generation equipment 21 and the charging and discharging status of the first supply and demand adjustment device 11. Furthermore, error information and other similar information can be cited.
[0043] Furthermore, the power conditioner 22 is designed to maximize the power generation of each solar module. Maximum Power Point Tracking (Maximum Power Point Tracking) automatically controls the power point (value of current × voltage). It is equipped with an optimizer that performs Point Tracking (MPPT) control. That's fine.
[0044] [Management Support System 1] Next, the management support system 1 of this embodiment will be described. As shown in Figure 1, the management support system 1 is produced by the renewable energy power generation mechanism 20. A power demand adjustment system 10 for adjusting the demand for renewable energy, and a control device. It includes a management device 60 that acquires information such as the amount of electricity received E5 from 13. The following describes each component.
[0045] First, let me explain the power demand adjustment system 10. The electricity demand adjustment system 10, as shown in Figure 1, uses renewable energy First supply and demand adjustment to adjust the demand for renewable energy produced at the Ghee power generation mechanism 20. Electricity output from device 11 and renewable energy generation mechanism 20 and supplied to apartment building 70. A measuring device 12 for measuring quantity E6, and a control device for controlling the renewable energy generation mechanism 20. It has a 13-pointed socket.
[0046] The first supply and demand adjustment device 11 is equipped with a first storage battery. The first battery allows for the generation of renewable energy under predetermined conditions, for example, the amount of electricity consumed by a specific group of rooms 71C. If the amount of electricity generated from the energy generation mechanism 20 falls below this amount, energy storage will be initiated, and the designated living room group 71C The supply will begin when the electricity consumption exceeds the amount of electricity generated by the solar power generation equipment 21.
[0047] Furthermore, the first supply and demand adjustment device 11 adjusts the amount of power generated at the solar power generation facility 21 using a power conditioner. Even if the processing capacity of Na22 is exceeded, surplus power can be stored. In that case, If the amount of electricity generated from the solar power generation equipment 21 falls below the processing capacity of the power conditioner 22 It can discharge electricity.
[0048] Furthermore, once the first supply and demand adjustment device 11 has stored energy up to a predetermined maximum capacity, the first supply and demand adjustment device will... The power storage to the regulating device 11 can be stopped. Furthermore, once the discharge reaches a predetermined minimum capacity, the discharge from the first supply and demand adjustment device 11 is stopped. It can be stopped.
[0049] The first supply and demand adjustment device 11 stores the DC power from the solar power generation equipment 21 as is. It may be present. In that case, the facility load 73 of the living room 71 and the power grid will be affected by the first supply and demand adjustment device 11. When power is supplied to the 100 side, the DC power taken from the first supply and demand adjustment device 11 is used The power conditioner 22 converts the power to AC power and supplies it.
[0050] Furthermore, the first supply and demand adjustment device 11 receives power from the power company that supplies power via the power transmission network 100. When the purchase price P1 for the amount of electricity received by apartment building 70, E1, changes depending on the time of day, You can also purchase electricity during times when the purchase price P1 is lower and store it.
[0051] Next, the measuring device 12 will be described. The measuring device 12 measures the amount of electricity output from the solar power generation equipment 21 or the first supply and demand adjustment device 11. This is for measuring E6 and outputting the acquired data to the control device 13. In this embodiment, a power generation meter is used as the measuring device 12. The power generation meter is a certified meter device that is verified in accordance with the Measurement Law, and is within the validity period of the verification. That is the case. The power generation meter controls the amount of electricity E6 per arbitrary unit of time (T), such as 1 second, 30 minutes, or 1 hour. Output to device 13.
[0052] The measuring device 12 may also be a smart meter. Furthermore, if permitted by amendments to the Measurement Act, etc., a power meter may be used instead of a power generation meter. The conditioner 22 measures the amount of electricity E6 output from the solar power generation equipment 21 or the first storage battery. It may also be used for setting and outputting the acquired data to the control device 13. In other words, in this case The power conditioner 22 also functions as a measuring device 12.
[0053] Next, the control device 13 will be described. The control device 13 includes a data acquisition unit 12a and a control unit 12b.
[0054] The data acquisition unit 12a includes an upper meter device 81, a lower meter device 84, and a measuring device 12 The amount of power measured by the device is periodically acquired and output to the control unit 12b and the management device 60. Furthermore, the data acquisition unit 12a acquires operation logs from the power conditioner 22 and manages them. Output to device 60.
[0055] The data acquisition unit 12a communicates with the renewable energy generation organization via the communication network 61. Weather information for the locations of apartment buildings 20 and 70, and the electricity that apartment buildings 70 receive from the power company, as described below. Obtain information on the purchase price P1 for the amount of electricity received E1. Furthermore, information on the standard price X and the selection criteria for the aforementioned specific room 71A will be collected. It's advantageous.
[0056] The control unit 12b receives the acquired data from the upper-level meter device 81, the lower-level meter device 84, and the measuring device 1 Based on the information on the amount of electricity measured in 2, the power conditioner 22 is controlled, and the first supply and demand adjustment is performed. The system controls the charging and discharging of the regulating device 11 and adjusts the supply of renewable energy as described later. . Thus, in this embodiment, the CT (Current Transformer) sensor Without using the method described below, the supply adjustment of renewable energy can be carried out, and this implementation The use of the management support system 1 can be easily initiated. Specifically, by using a CT sensor to detect the forward power flow from the power grid 100, The amount of electricity produced by the solar power generation facility 21 and the amount of electricity supplied from the first supply and demand adjustment device 11 are, Check whether the electricity consumption is below that of a 70A apartment building load, and then select renewable energy. It is also possible to adjust the supply. In that case, the power consumption of the apartment building load of 70A will be reduced. To check whether it is rotating or not, the CT sensor is placed between the upper meter 81 and the central power receiving panel 82. It needs to be installed on the power distribution line, but the type of power distribution line and the wiring situation, such as if the line is thick, will affect the installation. In some cases, it may be difficult to install a CT sensor. In contrast, if there is a lower meter 84 and a control device 13, the supply adjustment of renewable energy can be performed. It is possible to do so.
[0057] The control device 13 adjusts the supply of renewable energy, as described later, Predicted power supply amounts S1 and S2 are generated from the Ghee power generation mechanism 20. The prediction of the predicted power supply amounts S1 and S2 can be made using known methods as appropriate, and data collection The weather information for the following day at the location of the renewable energy power generation organization 20, which is stored in section 12a, You may proceed based on this.
[0058] The control device 13 adjusts the supply of renewable energy as described later, and also adjusts the supply of specific residences as described later. In order to predict the total electricity demand D1 and total electricity demand D2 for room group 71C, We will forecast the electricity demand for facilities 71 and shared facilities 72. The electricity demand forecast for each room 71 and shared facilities 72 can be appropriately calculated using known methods. For example, the past data for each room 71 stored in the data collection unit 12a for each hour of the following day This may be done based on the daily electricity consumption. Also, the electricity demand forecast for each of the 71 rooms is Alternatively, weather information for the location of the apartment building 70 stored in the data collection unit 12a may be used. stomach.
[0059] The control unit 12b is stored in the storage unit of the control device 13 (not shown) or an external storage medium. The CPU (Central Processor) is used to execute a program that defines the control procedure. This includes processors such as the ssing unit. The control unit 12b can communicate with the management device 60 via the communication network 61. The information created by the control unit 12b can be output to the management device 60.
[0060] Next, the control device 60 will be described. The management device 60 acquires information such as power consumption from the control device 13 and manages the meter reading data. Support, assistance in creating billing data D, and tracking trends in electricity usage for residents and managers. To reduce electricity consumption, we will provide services such as visualization of electricity usage. Furthermore, when the management device 60 obtains error information from the control device 13, the management device 60's The monitoring staff will receive notifications via voice, lights, images, video, phone, email, etc., indicating that an error has occurred. To notify them of this.
[0061] The management device 60, in order to create the billing data D, uses at least the first rule and the second rule. I remember approximately the third and fourth terms.
[0062] The first regulation is the purchase price for the amount of electricity E1 received by the apartment building 70 from the power company. P1 is defined. In this embodiment, the purchase price P1 is P1a during the day and P1d at night. These are determined for each time slot. As shown in Figure 3, the purchase price P1a is set higher than the purchase price P1d. Yes, they are.
[0063] The second regulation stipulates the sales price F1 for the amount of electricity E2 supplied to the power company. The selling price F1 is determined in agreement with the power company and is subject to the fixed-price purchase system for electricity. During the purchase period, the purchase price set by the fixed-price purchase system will be the selling price F1. Outside of the purchase period, the purchase price determined based on an arbitrary negotiated contract will be the selling price F1. .
[0064] The third provision is that the amount of electricity supplied by the power company that is sold to room 71 is limited to the amount of electricity received by the room. Determine the selling price F2. The selling price F2 is determined by the purchase price P1, such as purchase price P1a, purchase price P1d, etc., which are set for each time period. If applicable, the selling price F2a will be based on the purchase price P1a, and the selling price F2a will be based on the purchase price P1d. The selling price can be set according to the time of day, as in F2b. If the purchase price P1d is lower than the daytime purchase price P1a, then the residents of each room 71 will have the daytime purchase price P1d. Electricity can be used more cheaply during nighttime hours.
[0065] The fourth provision states that the electricity supplied by the renewable energy generation organization 20 to the living room 71 The selling price F3 is determined based on the amount of electricity consumed. The selling price F3 is set to be lower than the selling price F2. The resident of permanent room 71A will have priority over electricity supplied by the renewable energy generation organization 20. By using it, you can lower your electricity bill. The selling price F3 is preferably higher than the selling price F1. This is because the apartment building 70 The owners can earn more profit from renewable energy than from selling electricity to power companies. This could be a major motivation for introducing the power generation mechanism 20. Based on the above, it is preferable that the sales price F1, sales price F2, and sales fee F3 have the following relationship. It seems so. Selling price F2 > Selling fee F3 > Selling price F1
[0066] The management device 60 may be installed outside the apartment building 70, or it may be installed inside the apartment building 70. That's fine.
[0067] Communication network 61 uses LTE (long Term Evolution) and Wi-Fi. It consists of wireless communication networks using fi (registered trademark), etc., and wired communication networks using fiber optic lines, etc. It is being done. The communication network 61 is a combination of multiple wireless and wired communication networks as described above. It may be composed of such things. Furthermore, in this embodiment, communication between the power conditioner 22 and the control device 13 is performed as follows: It complies with ECHONET Lite (registered trademark), but also Modbus (registered trademark) and other technologies. Even if the data is transmitted using the manufacturer's proprietary protocol for the War Conditioner 22, Good. Furthermore, communication between the control device 13 and the management device 60 may be performed based on other communication methods. good.
[0068] The management support system 1 of this embodiment, configured as described above, is for renewable energy generation. The electricity generated by the mechanism 20 is supplied to the designated living room group 71C.
[0069] <Method for adjusting the supply of renewable energy using management support system 1> The following describes the renewable energy produced by the renewable energy generation mechanism 20 using the management support system 1. The method for adjusting the supply of available energy will be explained using Figures 3 and 4.
[0070] The management support system 1 of this embodiment is First, in step 1-1, set up the specific room group 71C. Set up the specific room group 71C. Once confirmed, proceed to step 1-2.
[0071] Next, in step 1-2, the power consumption of the specific room 71A that constitutes the specific room group 71C. The total power consumption of the specific living room group 71C is calculated, and the renewable energy generation organization 20 We determine the power supply and compare the calculated power consumption with the power supply. If the power consumption is greater than the power supply (Figure 4: S1-2 N), proceed to step 1-3. To do. On the other hand, if the power consumption is less than the power supply (Figure 4: S1-2 Y), the following steps will be described later. Proceed to steps 1-9.
[0072] Next, in Step 1-3, the high-price time period is when the purchase price P1 exceeds the base price X. Determine the start time T1 and end time T2 of H. Specifically, as shown in Figure 3, in this embodiment, the purchase price P1 is the purchase price during the daytime. P1a and P1d are set as the purchase price for nighttime purchases. And since the purchase price P1a is higher than the base price X, the purchase price P1a The set time period is designated as the high-price time period H, and the start time T1 and end time of the high-price time period H are determined. Determine time T2. Once the start time T1 and end time T2 of the high-price time zone H are determined, proceed to step 1-4. ru.
[0073] Next, in Step 1-4, the high-price time zone H that was identified in Step 1-3 is Check. If the price falls within the high-price time zone H (Figure 4: S1-4 Y), proceed to step 1-5. On the other hand, if it is not within the high-price time period H (Figure 4: S1-4 N), then step 1 described later... It transitions to -10.
[0074] In Steps 1-5, from the current time to the end time T2 determined in Steps 1-3. Predicts a predetermined amount of power. Specifically, the predicted total electricity demand D1 for the specific facility group 71C and the first supply and demand adjustment device 11 The possible supply amount C1 and the predicted supply amount S1 from the renewable energy generation organization 20 are predicted. ru. Once the prediction of energy consumption D1, C1, and S1 is complete, proceed to steps 1-6.
[0075] Next, in step 1-6, the first supply and demand adjustment device 11 obtained in step 1-5 Using the possible supply amount C1 and the predicted supply amount S1 from the renewable energy generation organization 20, Confirm whether to change the permanent room group 71C.
[0076] Specifically, the predicted total electricity demand D1 and the possible supply amount C1 from the first supply and demand adjustment device 11. This is compared with the total predicted supply S1 from the renewable energy generation organization 20. If the comparison shows that the predicted total electricity demand D1 is greater, then the possible supply C1 and the predicted supply Based on the total amount S1 and the selection criteria for the specified room 71A mentioned above, the first supply and demand adjustment system The possible supply amount C1 from the facility 11 and the predicted supply amount S1 from the renewable energy generation organization 20 The number of specific rooms 71A that make up specific room group 71C is reduced so that it is approximately equal to the total. On the other hand, if the predicted total electricity demand D1 is less, select the specific room 71A as described above. Based on the selection criteria and the selection criteria for selecting the specific room 71A mentioned above, general room 71B or Then, a specific room 71A is newly selected, and the possible supply amount C1 from the first supply and demand adjustment device 11 and the regeneration The total amount of predicted supply S1 from the available energy generation mechanism 20 is approximately equal to the specific residence Add to chamber group 71C. Furthermore, the predicted total electricity demand D1 and the possible supply amount C1 from the first supply and demand adjustment device 11 are used. If the total of the predicted supply amounts S1 from the bio-energy generation organization 20 is approximately equal, then the specific room The number of specific rooms 71A that make up group 71C will remain unchanged.
[0077] After the revised total electricity demand D1 for the specific room group 71C was predicted again, Proceed to steps 1-7.
[0078] In steps 1-7, the first downward DR (Demand Response) is performed. Generally, the facility load of 73 is reduced during designated periods to balance supply and demand. This is how reduced DR is achieved, but in this embodiment, the battery is discharged during a predetermined time period. By using electricity in this way, the power supply from the power company during that time period can be reduced. And that's how they've achieved a lower DR (Digital Rating).
[0079] Specifically, during the high-price period H, the power supply from the power grid 100 to the specific group of rooms 71C To suppress the supply, discharge is initiated from the first supply and demand adjustment device 11. In the first downward demand response (DR), discharge will be carried out up to the predicted total electricity demand D1.
[0080] Steps 1-7 are determined to be based on the assumption that in Step 1-8, time T has elapsed. (Figure 4: S1-8 Y), after going through steps 1-15 described later, we return to step 1-1. This continues until [the specified step]. Steps 1-9, 1-13, and 1-14 described below. The same applies to this as well.
[0081] Next, we will explain steps 1-9. In steps 1-9, perform the first upward DR. Specifically, as described above, in step 1-2, the power consumption is less than the power supply. Since it has been determined that (Figure 4: S1-2 Y), surplus power is stored in the first supply and demand adjustment device 11. To electrify. The energy stored in the first upward DR is from renewable energy generation, as determined in steps 1-2 above. The calculation is performed with a maximum value obtained by subtracting the power consumption of the specific living room group 71C from the power supplied from the mechanism 20. Furthermore, if the first supply and demand adjustment device 11 is charged to its predetermined maximum capacity, the first supply and demand adjustment device will be charged. The power supply to the power adjustment device 11 is stopped and supplied to the general living room 71B.
[0082] Next, we will explain steps 1-10. In Step 1-10, as described in Step 1-4 above, if it is within the high-price time period H This is the state in which the judgment is being made (Figure 4: S1-4 N). In Step 1-10, the trends in power consumption of the specific room group 71C and one or more rechargeable devices We predict the trend of the total supply from the biomass energy generation organization 20, and the total supply from the power consumption Predict time T3 when the volume will be highest. Once the prediction for time T3 is complete, proceed to step 1-11.
[0083] In step 1-11, predict a predetermined amount of power from start time T1 to time T3. . Specifically, the estimated total power demand for the specific facility group 71C from start time T1 to time T3. Amount D2, possible supply amount C2 from the first supply and demand adjustment device 11, and renewable energy generation mechanism Predict supply quantity S2 from 20. Once the prediction of energy consumption D2, C2, and S2 is complete, proceed to step 1-12.
[0084] In step 1-12, the energy quantities D2, C2, and S2 obtained in step 1-11 are used. Next, we will confirm whether to change the designated room group 71C. Specifically, as shown below, the total electricity demand D2 is used to calculate the renewable energy generation organization 2 The value obtained by subtracting the predicted supply amount S2 from 0 is compared with the possible supply amount C2 from the first supply and demand adjustment device 11. To compare. D2-S2>C2
[0085] This value is obtained by subtracting the predicted supply amount S2 from the renewable energy generation organization 20 from the required electricity amount D2. However, if the available supply amount C2 is less (Figure 4: S1-12 N), then step 1-13 It will transition to [this]. On the other hand, if the available supply amount C2 is greater (Figure 4: S1-12 Y), the following steps will be taken. Proceed to 1-14.
[0086] In Step 1-13, perform the second downward DR. Specifically, the seven specific facility groups from start time T1 to time T3, determined in step 1-11. From the predicted total electricity demand D2 of 1C, the predicted supply amount from the renewable energy generation organization 20 The value obtained by subtracting S2 is preferable to the supply supplied from the supply adjustment device 11 from the start time T1 to time T3. This results in a reasonable amount of electricity, but it is less than the possible supply amount C2 from the first supply and demand adjustment device 11. Therefore, it was determined that there was a surplus in the possible supply amount C2, and the discharge was opened from the first supply and demand adjustment device 11. It begins. Discharge in the second downward DR is from renewable energy generators, based on the predicted total electricity demand D2. The value obtained by subtracting the predicted supply amount S2 from structure 20 is performed up to the value obtained by subtracting the possible supply amount C2. ru.
[0087] Next, we will explain steps 1-14. In Step 1-14, perform the second upward DR. Specifically, the seven specific facility groups from start time T1 to time T3, determined in step 1-11. From the predicted total electricity demand D2 of 1C, the predicted supply amount from the renewable energy generation organization 20 The value obtained by subtracting S2 is preferable to the supply supplied from the supply adjustment device 11 from the start time T1 to time T3. This will result in a significant amount of electricity. Since this is greater than the possible supply amount C2 from the first supply and demand adjustment device 11, the start time T1 Before that, the power supply adjustment device 11 is preferably supplied from start time T1 to time T3. The amount that is insufficient is stored in the first supply and demand adjustment device 11 by receiving power from the power transmission network 100. do. Thus, the first supply and demand adjustment is performed by receiving power from the power grid 100 before the start time T1. By storing energy in device 11, the economic burden on bulk power supply operators can be reduced. Furthermore, the fact that we have moved to step 1-14 means that the power consumption of the specific room group 71C is , because it is greater than the power supplied from the renewable energy generation organization 20 (Figure 4 S 1-2 N) While the first supply and demand adjustment device 11 is storing electricity, the power grid also transmits to the specific room group 71C. Power will be supplied from the 100V side.
[0088] Next, we will explain steps 1-15. Steps 1-15 are based on the assumption that in Step 1-8, time T has elapsed. This occurs when (Figure 4: S1-8 Y). In step 1-15, a predetermined amount of power is measured during time T. Specifically, the reverse flow rate TE2 of the upper meter device 81 and the lower meter device of the specific room 71A The forward tidal flow rate TE5a of the meter 84 and the forward tidal flow rate TE5b of the lower meter device 84 in the general living room 71B. And the amount supplied from the renewable energy generation organization 20, TE6a, and the first supply and demand adjustment device 11 The supply amount of TE6b and are measured. The reverse flow rate TE2 of the upper meter device 81 was measured by the upper meter device 81 during time T. It is calculated based on the amount of electricity E2. The normal flow rate TE5a of the lower meter device 84 in the specific room 71A, and the lower meter of the general room 71B The forward tidal flow rate TE5b of the metering device 84 is measured at the lower metering device 84 of each living room 71A for time T. It is calculated based on the amount of electricity E5 measured during that time. The amount supplied from the renewable energy generation organization 20, TE6a, and from the first supply and demand adjustment device 11 The supply amount TE6b is the amount of solar power output from the state detection unit of the power conditioner 22. The time measured by the measuring device 12 is determined based on the operating status of equipment 21 and the first supply and demand adjustment device 11. It is calculated from the amount of energy E6 during period T. Once the measurement of energy consumption TE2, TE5a, TE5b, TE6a, and TE6b is complete, then... Proceed to Step 1-1.
[0089] Next, we will explain how to create billing data D. First, using Figure 5, we will explain how to create billing data The calculation of the renewable energy utilization rate used in creating Data D will be explained, followed by Figure 6. We will now explain how to create the billing data D for each of the 71 rooms using this method.
[0090] <Calculation of renewable energy utilization rate> The calculation of the utilization rate of renewable energy will be explained using Figure 5. First, in step 2-1, the steps of the renewable energy supply adjustment method described above. The sum of the forward tidal flow rate TE5a measured in the lower meter device 84 of the specific room 71A in 1-15 Calculate the total. Once the total flow rate TE5a is calculated, proceed to step 2-2.
[0091] In step 2-2, the renewable energy utilization rate α1 of the first supply and demand adjustment device 11 is Calculate and determine the amount of renewable energy supply St. The amount of renewable energy supplied St is equal to the amount supplied T from the renewable energy generation organization 20. E6a and the amount of renewable energy generators supplied from the first supply and demand adjustment device 11 TE6b The reverse flow rate TE2 of the upper meter device 81 is calculated from the total amount of electricity supplied from structure 20. This is the result after subtracting [a certain value].
[0092] First, let's explain how to calculate the renewable energy utilization rate α1 of the first supply and demand adjustment device 11. I will reveal it. In the renewable energy supply adjustment method of this embodiment, as shown in Figure 4, Step 1 The first upward DR is performed at -9, and the second upward DR is performed at step 1-14. As mentioned above, the first DR is powered by the renewable energy generation organization 20. In response, the first supply and demand adjustment device 11 stores energy, and the second rise D of step 1-14 described above occurs. When R occurs, the first supply and demand adjustment device 11 stores energy after receiving power from the power transmission network 100. It can be done. Therefore, from past records, the first supply and demand adjustment device 11 in the first upward DR for a predetermined period From the amount of stored energy and the amount of stored energy in the first supply and demand adjustment device 11 during the second upward DR, the first supply and demand adjustment device 11 The renewable energy utilization rate α1 is calculated.
[0093] Next, in step 2-3, the amount of energy supplied from the renewable energy generation mechanism 20, St, Compare the total flow rate TE5a of the lower meter device 84 in specific room 71A. Based on the results of this comparison, the renewable energy utilization rate α2 of specific room 71A and general room The renewable energy utilization rate α3 for 71B can be calculated using different methods.
[0094] Specifically, the total of the forward tidal flow rates TE5a of the lower meter device 84 in specific room 71A is greater than the recurrent flow rate If the amount of St supplied from the bio-energy generation mechanism 20 is large (Figure 5 S2-3 >) In step 2-4, α2 is set to 100%, and α3 is calculated using the following formula. α3 = (Sum of St - TE5a) / Sum of TE5b
[0095] Then, the sum of the forward tidal flow rates TE5a of the lower meter device 84 of the specific room 71A and the regenerative energy If the amount of St supplied from the energy generation mechanism 20 is equal (Figure 5 S2-3 =), then St In step 2-5, α2 is set to 100% and α3 to 0%.
[0096] Furthermore, it is regenerative, exceeding the sum of the forward tidal flow rates TE5a of the lower meter device 84 of the specific room 71A. If the amount of energy supplied from the energy generation mechanism 20, St, is small (Figure 5 S2-3 <), In step 2-5, calculate α2 using the following formula and set α3 to 0%. α² = St / TE5a (sum)
[0097] If any of the steps 2-4 to 2-6 described above have been performed, and time T has elapsed, The result (Figure 5: S2-7 Y) proceeds back to step 2-1. Meanwhile, time T has elapsed. If this has not been done (Figure 5: S2-7 N), then it is determined again whether time T has elapsed.
[0098] <Creation of billing data D for each of the 71 rooms> Next, we will explain the creation of billing data D for each of the 71 rooms using Figure 6.
[0099] First, in step 3-1, at predetermined intervals T, the room 71 falls under the category of a specific room 71A. The process in the case of (Figure 6: S3-2~S3-4) and the process in the case of general room 71B To determine which of the following processes (Figure 6: S3-5~S3-7) will be performed, the billing date Determine whether room 71, where TaD is created, falls under the category of specific room 71A.
[0100] If the room 71 from which billing data D is created is a specific room 71A (Figure 6: S3 -1 Y), proceed to the process for when the room 71 described later corresponds to a specific room 71A. On the other hand, if it does not fall under the category of specific room 71A (Figure 6: S3-1 N), then room 71 is a general room Proceed to the process for cases corresponding to Room 71B. The following is the process when room 71 is designated as room 71A (Figure 6: S3-2~S3-4) ) will be explained, and then the process when room 71 corresponds to general room 71B (Figure 6: S3- 5~S3-7) will be explained.
[0101] The process will be explained when room 71 falls under the category of specified room 71A. First, in step 3-2, the above-mentioned S1- recorded in the recording unit of the management device 60 The billing data measured by the control unit 12b of the control device 12 at step 15 and output to the management device 60, Forward current flow during time T, measured by the lower meter device 84 of the specific room 71A that generates data D. The amount TE5a and the renewable energy utilization rate α calculated in S2-4 to S2-6 above. Get 2. Once you have obtained the tidal flow rate TE5a and the renewable energy utilization rate α2, proceed to step 3-3. Migrate.
[0102] Next, in step 3-4, the electricity supplied from the renewable energy generation organization 20 Create the first billing data D1, which is the billing data for that. Specifically, the forward tidal flow rate TE5a extracted in step 3-3 is also used in step 3 -3 The renewable energy utilization rate α2 extracted in -3 and the fourth set forth in the regulations The result is created by multiplying the selling price by F3. Once you have created the first billing data D1, proceed to step 3-4.
[0103] Next, in step 3-4, the billing process for the electricity supplied from the power grid 100 We will obtain the second billing data D2, which is the data. Specifically, the forward tidal flow rate TE5a extracted in step 3-3 is also used in step 3 -3 The value obtained by subtracting the renewable energy utilization rate α2 extracted in -3 from 1, and the fourth rule It is created by multiplying by the specified selling price F3. Once the second billing data D2 is created, if room 71 falls under the category of specific room 71A, Once this step is complete, we will proceed to step 3-8.
[0104] Next, the process when room 71 corresponds to general room 71B (Figure 6: S3-5~S3-7) I will explain this. First, in step 3-5, the above S1- recorded in the recording unit of the management device 60 The billing data measured by the control unit 12b of the control device 12 at step 15 and output to the management device 60, Forward current flow during time T, measured by the lower meter device 84 in the general living room 71B that creates data D. The tidal current volume TE5b and the utilization rate α of renewable energy calculated in S2-4 to S2-6 described above 3 are obtained. Once the tidal current volume TE5b and the utilization rate α3 of renewable energy are obtained, if the living room 71 corresponds to the specific living room 71A, similar to step 3-3 of the process in this case, in step 3-6, the first charge claim data D1 is created, and in step 3-7, similar to step 3-4, the second charge claim data D2 is created. Once the second charge claim data D2 is created, if the living room 71 corresponds to the general living room 71B, the process ends and the flow moves to step 3-8. Next, in step 3-8, the charge claim data D for the time period T is created. Specifically, in the case of the specific living room 71A, the second charge claim data D2 created in step 3-4 is added to the first charge claim data D1 created in step 3-3 to create the charge claim data D. On the other hand, in the case of the general living room 71B, the second charge claim data D2 created in step 3-7 is added to the first charge claim data D1 created in step 3-6 to create the charge claim data D. Once the charge claim data D is created, the flow moves to step 3-9.
[0105] Then, in step 3-9, it is determined whether the time has elapsed by T. If the time has elapsed by T (Fig. 6: S3-9 Y), the flow moves to step 3-1. On the other hand, if the time has not elapsed by T (Fig. 6: S3-9 N), it is again determined whether the time has elapsed by T.
[0106]
[0107] 〈Effects achieved by the business support system 1〉 Next, the effects achieved by the business support system 1 will be described. The management support system 1 of this embodiment includes a plurality of living rooms 71 and a power supply mechanism 80 for supplying power received in a lump from the power grid 10 to the plurality of living rooms 71. The power supply mechanism 80 can also supply the power generated by the renewable energy power generation facility 20 to the plurality of living rooms 71. In a rental property, when a certain facility is in a situation of being inferior in various conditions compared to other facilities in the same rental property, or in response to changes in the power supply situation from the renewable energy power generation facility due to weather, time zone, etc., one or more of the plurality of living rooms 71 are selected as specific living rooms 71.

[0111] [Second Embodiment] The second embodiment will be described below with reference to Figure 7. Components similar to those in the first embodiment are denoted by the same reference numerals as in the first embodiment, and their descriptions are omitted. . In Figure 7, the solid lines connecting each block indicate the flow of power, and the lines connecting each functional block... The dashed lines indicate the flow of control signals or communicated information.
[0112] As shown in Figure 7, the management support system 1A of this embodiment has a second supply and demand adjustment device in the living room 71. A support 14 is provided. The second power supply and demand adjustment device 14 warms water using surplus power generated by the solar power generation facility 21 and may be a hot water machine that stores the hot water thus produced, or an ice making machine that stores ice made by freezing water using surplus power generated by the solar power generation facility 21.

When provided outside the living room 71, it is preferably provided so that only the residents of the living room 71 can use it.
[0113] Providing the second power supply and demand adjustment device 14 in the living room 71 can meet the above-described selection conditions. [[ID=1
[17] ]
[0114] In this embodiment, in the method for adjusting the supply of renewable energy, in steps 1-9, when charging is stopped at the first power supply and demand adjustment device 11 after charging up to a predetermined maximum capacity in the first power supply and demand adjustment device 11, it may be supplied to the second power supply and demand adjustment device 14, or the first power supply and demand adjustment device 11 and the second power supply and demand adjustment device 14 may operate in parallel. Also, in steps 1-14, power is supplied from the first power supply and demand adjustment device 11 to the second power supply and demand adjustment device 14 in a specific living room 71A, and then power is supplied from the power grid 100 side to charge the first power supply and demand adjustment device 11. As shown in FIG. 3, step 1-14 is a time zone before the start time T1 of the next high-price time zone H after passing through the high-price time zone H. Therefore, even for a living room 71 that is changed from a specific living room 71A to a general living room 71B within the high-price time zone H according to the set selection conditions, power is supplied from the first power supply and demand adjustment device 11 to the second power supply and demand adjustment device 14 in the specific living room 71A in the time zone before the start time T1, During the time period when the room 71 equipped with the second supply and demand adjustment device 14 does not fall under the category of specified facility 71A This can increase opportunities to use renewable energy and improve the utilization rate of renewable energy. It can be improved.
[0115] The second supply and demand adjustment device 14 may also be a battery. If the second supply and demand adjustment device 14 is a battery, in step 1-14, the first supply and demand adjustment Similar to the adjustment device 11, charging is performed at the purchase price P1d. This means that we have moved to Step 1-14, which is the estimated total for the specific facility group 71C. The value obtained by subtracting the predicted supply amount S2 from the renewable energy generation organization 20 from the electricity demand amount D2. However, this is greater than the possible supply amount C2 from the first supply and demand adjustment device 11 (Figure 4 S1-1 (See 2) This deficit can be secured before the start time T1 of the high-price period H.
[0116] Next, we will explain the effects achieved by the management support system 1 of the second embodiment. The management support system 1 of this embodiment is located in a room 71 where the second supply and demand adjustment device 14 is installed. When this is selected as a specific room 71A, renewable energy generation will be possible during the first DR. To prevent reverse power flow from the power supply mechanism 20 to the power transmission grid 100 and to utilize it effectively. It is possible.
[0117] [Third Embodiment] The third embodiment will be described below with reference to Figure 8. Components similar to those in the first embodiment are denoted by the same reference numerals as in the first embodiment, and their descriptions are omitted. . In Figure 8, the solid lines connecting each block indicate the flow of power, and the lines connecting each functional block... The dashed lines indicate the flow of control signals or communicated information.
[0118] As shown in Figure 8, the management support system 1B of this embodiment is for one building, as in the first embodiment. In addition to apartment building 70, the rental apartments consist of apartment building 70B. Used for group properties. Unlike apartment building 70, apartment building 70B, as shown in Figure 8, is equipped with renewable energy sources. It does not receive power directly from the power supply organization 20. Apartment building 70B is the same building as apartment building 70, which received power from the renewable energy generation organization 20. Of the electricity, the reverse power flow E2 measured by the upper-level metering device 81 was used in the apartment building 70B. The fee is calculated based on this assumption. This allows for the designation of a specific habitable room 71A, similar to the apartment building 70.
[0119] The method for calculating fees in this embodiment will be described below, mainly with reference to Figures 5 and 6, in the first embodiment. This section will explain the process, which differs from the application method. Unlike the first embodiment, this embodiment has a multi-unit dwelling 70B with a renewable energy power generation mechanism 2 Since it does not receive power supply directly from 0, in step 2-2, the first supply and demand adjustment device 1 It is necessary to consider the utilization rate of renewable energy α1 and the reverse power flow from apartment building 70B. stomach. Therefore, the amount of renewable energy supplied St is equivalent to the top 70 meters of electricity used in apartment buildings during time T. TE2 can be calculated based on the reverse power flow E2 measured by the device 81.
[0120] Then, in Step 2-3, during the time T certified as St, the top 70 apartment buildings Based on the reverse power flow E2 measured by the meter device 81, TE2 was calculated, and the special characteristics of the apartment building 70B Compare the total forward tidal flow rates TE5a measured by the lower meter device 84 in the permanent living room 71A.
[0121] Similar to the first embodiment, proceed to one of steps 2-4 to 2-6 based on the comparison results. Then, the renewable energy utilization rate α2 of the specific room 71A and the renewable energy utilization rate of the general room 71B The energy utilization rate α3 is calculated. Then, as shown in Figure 6, the calculated α2 or α3 is used to bill each facility 71. Data is created.
[0122] Next, we will explain the effects achieved by the management support system 1B of the third embodiment. In this embodiment, the power supply is not directly received from the renewable energy generation mechanism 20. Even for apartment buildings 70B that do not have any residents, the management support system 1B can be easily used. Furthermore, multiple apartment buildings 70B can be managed in the same way as the single apartment building 70 in the first embodiment. Because it can be managed, it can sometimes make it easier to adjust the demand for renewable energy.
[0123] In the first embodiment, the selection conditions for each living room 71 were described, but in this embodiment... The distance from apartment building 70 to the nearest station and the age of apartment building 70 are among the factors that determine the cost of the apartment building. If there are conditions that make it difficult to secure tenants for the entire housing complex 70B, one or more buildings It is also possible to designate all 71 rooms in apartment building 70B of the building as specific rooms.
[0124] Furthermore, the rental property complex is directly connected to the Renewable Energy Power Generation Organization 20. It is acceptable for multiple units of Residential Building 70 to be included, and for multiple units of Apartment Building 70B to be included.
[0125] The method for calculating fees when a property includes multiple units of either Apartment Building 70 or Apartment Building 70B is shown in the diagram. Referring to Figures 5 and 6, the steps that differ mainly from those of the first embodiment will be described. In Step 2-2, unlike the first embodiment, the apartment building 70B is renewable energy Since it does not receive power supply directly from the power generation mechanism 20, the first supply and demand adjustment device 11 has a renewable energy We will calculate only the amount of renewable energy supplied, St, without calculating the energy utilization rate α1.
[0126] Of the multiple apartment buildings in the 70B complex, the nth apartment building, 70Bn, utilizes renewable energy. The supply amount St of ghee is calculated by distributing the reverse flow from apartment complex 70 to apartment complex 70B equally. Assuming that this is the case, it can be calculated using the following formula. St = (Total TE2 of apartment complex 70 / Total TE1 of apartment complex 70B) × Apartment complex 70 Bn's TE1 value
[0127] Alternatively, it can be determined by assigning priority levels within the 70B group of apartment buildings. For example, if apartment building 70Bn with a smaller n value is prioritized, then first, From the total value of TE2 for apartment building 70A, from TE1 of apartment building 70B1 to apartment building 70Bn The values are subtracted sequentially up to TE1. When subtracted in this way, the value of TE1 is less than the remaining total value of TE2 for the 70 apartment complexes. A large apartment complex, 70Bn+1, was detected. For apartment buildings up to 70Bn, the amount of renewable energy supplied can be calculated as ST=TE1. . Then, in the apartment complex 70Bn+1, the amount of renewable energy supplied, St, is calculated using the following formula. It can be seen. St = (Total remaining TE2 for 70 apartment complexes / TE1 value for 70Bx apartment complexes) × Apartment complex Value of TE1 for home 70Bn+1 Furthermore, from the next apartment building after apartment building 70Bn+1, apartment building 70Bn+2, renewable energy - The supply amount St = 0 is used to determine this.
[0128] Then, using the amount of renewable energy supply St obtained as described above, step In 2-3, the forward tidal flow rate TE of the lower meter device 84 of the specific room 71A of the apartment building 70B. Compare the totals of 5a.
[0129] Similar to the first embodiment, proceed to one of steps 2-4 to 2-6 based on the comparison results. Then, the renewable energy utilization rate α2 of the specific room 71A and the renewable energy utilization rate of the general room 71B The energy utilization rate α3 is calculated. Then, as shown in Figure 6, the calculated α2 or α3 is used to bill each facility 71. Data is created.
