In FIG. 3, the data communication line is indicated by a solid line, and the power transmission line is indicated by a broken line.

  The present system S is a so-called CEMS, and is used for the purpose of managing power supply and demand in the use area. In describing the configuration of the system S, the usage area of the system S will be described. This system S is used in the specific area AR shown in FIG. 1 where a plurality of houses are constructed. Here, the “specific area AR” is an area where a single-family house (hereinafter referred to as a house H) is assembled like a town house, and in this embodiment, 10 to 100 houses are built. It means an area of a certain section including a house H of a degree. However, the specific area AR may be a wider area, for example, an area in units of administrative divisions. Further, the house in the specific area AR is not limited to a single-family house, and may be a plurality of houses in the same building such as an apartment or an apartment.

  Each of the plurality of houses H in the specific area AR has a solar cell panel on the roof. This solar cell panel corresponds to an example of a residential power generation facility, and is hereinafter referred to as a residential PV1. The house-side power generation equipment is not limited to solar cell panels, but is one that generates power using natural energy other than sunlight, such as wind power generation equipment or geothermal power generation equipment, or a fuel cell or gas engine. You may generate electric power using auxiliary fuel, such as power generation equipment.

  Moreover, as shown in FIG. 1, the photovoltaic power generation unit which consists of a solar cell panel is installed as a shared installation in the common space (place different from the place where the house H was built) in specific area AR. This solar power generation unit corresponds to a shared power generation facility shared by residents of a plurality of houses H in the specific area AR, and is hereinafter referred to as a shared PV2. Note that the shared power generation facilities are not limited to solar cell panels, but also generate power using natural energy other than sunlight, such as wind power generation facilities and geothermal power generation facilities, or fuel cells and gas engine power generation facilities. The power may be generated using auxiliary fuel such as the above.

  The shared PV 2 will be described. A solar cell panel placed on a panel mount installed on a flat ground in the specific area AR, and a solar cell panel installed on the roof of the mobility station C constructed in the specific area AR. , Is composed of. The mobility station C is a garage that stores a small electric vehicle (hereinafter, mobility 3) that is a power consuming device. Note that the mobility station C and its accessory devices (for example, lighting devices) and the mobility 3 and its accessory devices (for example, the power supply device that supplies power to the mobility 3) are jointly used by residents of each house H in the specific area AR. Corresponds to available shared facilities.

  The shared PV 2 is relatively large and has a significantly larger output power than the house-side PV 1 installed in each house H. More specifically, in this embodiment, the rated output (maximum value) of the residential PV1 is about 1 to 10 kW, whereas the rated output (maximum value) of the shared PV2 is set to about 50 to 200 kW. Yes.

  Next, the electrical system in the specific area AR will be described with reference to FIG. Each house H in the specific area AR is supplied with power supplied from the commercial power supply 4 (hereinafter, system power). Moreover, the above-mentioned house side PV1 is installed in each house H, The generated electric power is converted into alternating current power by the power conditioner not shown, and is supplied in the house. That is, the generated power and the grid power of the house side PV 1 are supplied to the home appliance 6 in the house via the distribution board 5.

  Each house H is provided with a storage battery 7 made of a lithium ion battery or the like, and part of the generated power and system power can be stored in the storage battery 7. Furthermore, about the generated electric power of the house side PV1, it is possible to sell some or all of them. More specifically, each house H is provided with a reverse power flow line, and when the switch SW provided in the line is turned on, the generated power of the house side PV1 is an electric power purchaser. Power is transmitted toward the electric power company K1. As described above, the electric power generated by the house-side PV1 is purchased by the electric power company K1, so that the residents of the house H that is the transmission source can obtain profits according to the purchased power.

  On the other hand, almost all of the power generated by the shared PV 2 described above is sold, except for a certain amount of power. The electric power sold is converted into points (points will be described later) and distributed to each house H in the specific area AR. In this way, almost all of the generated power of the shared PV 2 is sold, so that the power sale profit becomes relatively large. As a result, the points allocated to each house H also increase. That is, with the configuration of the system S, the residents of each house H can greatly benefit from the shared PV 2.

  A part of the generated power of the shared PV 2 is consumed in the mobility 3 and the mobility station C as shared facilities. Specifically, in the mobility station C, a storage battery 8 as a power storage device is installed. The electric power stored in the storage battery 8 is used for the lighting device 9 in the mobility station C or used as a power supply source for the mobility 3. And the electric power equivalent to a predetermined ratio (for example, about 1 to 10%) of the generated electric power of the shared PV 2 is to be stored in the storage battery 8. In addition, about the mobility 3 and the mobility station C, when an electric power demand cannot be covered only with the electric power supplied from shared PV2, the shortage is to be compensated with system power.

  Incidentally, a plurality of storage batteries 8 used in the mobility station C may be prepared and at least one of them may be portable. With such a configuration, the storage battery 8 can be used as an emergency power source when a power failure occurs in the entire specific area AR due to a disaster or an accident.

  Next, the device configuration of the system S will be described. The system S includes the above-described mechanism relating to power supply and the mechanism related to data communication illustrated in FIG. 3 as main components.

It has been.

  The home server 10 is provided for each house H in the specific area AR. The home server 10 constructs a HEMS (Home Energy Management System) in each house H. That is, the home server 10 functions as a home gateway, monitors the power supply / demand situation in the home through a communication network built in the home (hereinafter referred to as the home network TN), and remotely controls each home appliance 6 in the home.

More specifically, power sensors E1 to E5 are installed at various locations in the home, and the home server 1 communicates with the power sensors E1 to E5 through the home network TN and acquires the measurement results. In addition, about the measurement object of each electric power sensor E1-E5, it is as showing to the following (t1)-(t5). However, power measurement targets other than the following may be added to power measurement targets in the home.
(T1) Power sensor E1: Total power load at house H (t2) Power sensor E2: Power transmitted to storage battery 7 (t3) Power sensor E3: Generated power of house side PV1 (t4) Power sensor E4: House side Electric power transmitted to the electric power company K1 among the electric power generated by PV1 (t5) Power sensor E5: Electric power fed from the commercial power supply 4 (system power)

  The home server 10 visualizes (numerizes or graphs) the measurement results of the power sensors E1 to E5, and notifies the residents of the house H where the home server 10 is installed. The residents can check the current power supply and demand situation at home from the notification content. At this time, the residents use the user terminal 11 equipped with a display as an interface device. The user terminal 11 constitutes a residential terminal together with the home server 10, and the power supply / demand situation visualized by the home server 1 is displayed on the display (corresponding to a display).

  The user terminal 11 will be described. The user terminal 11 has a function of communicating with the home server 1 through the home network TN and a function of displaying information obtained through communication with the home server 1 on a display. The user terminal 11 according to the present embodiment is configured by a tablet-type PDA (Personal Digital Assistant) owned by a resident. However, the present invention is not limited to this, and may be a smart phone, a mobile phone, a PC, or a digital photo frame or television equipped with a communication function owned by the residents.

  The user terminal 11 according to the present embodiment includes a touch panel display, and has a function of detecting an operation (touch operation) performed by a resident through the touch panel. The mechanism for detecting the operation performed by the residents is not limited to the touch panel, and may be an input device such as a keyboard or a voice recognition device.

  The center server 20 is a server that supervises the system S, and is managed by an administrative organization that has jurisdiction over the specific area AR, or a construction company that has built each house H in the specific area AR. The center server 20 can communicate with the home server 10, the electric power company server 30, and the service provider company server 40 of each house H through a communication network such as the Internet (hereinafter referred to as an external network GN).

  And the center server 20 is provided with the power supply-and-demand totaling function which is a core function of CEMS. This function is a function that collects information related to power supply and demand in specific area AR locations and aggregates it as the supply and demand situation of the entire area. More specifically, the center server 20 communicates with the home server 10 of each house H, and receives data indicating power consumption in each house H (hereinafter, power consumption data). The center server 20 communicates with a power sensor E6 that measures power consumed by the mobility station C and the mobility 3 (in other words, discharged power from the storage battery 8), and receives data indicating the measurement result. And the center server 20 calculates the total power consumption (henceforth area whole area power consumption) in the specific area AR whole area based on the power consumption data for all the houses H, and the measurement result data of the electric power sensor E6. In calculating the area-wide power consumption, the power consumption in a shared facility (for example, a streetlight) other than the mobility station C and the mobility 3 may be measured, and the measurement result may be added to the area-wide power consumption.

  The center server 20 communicates with a power sensor E7 that measures the generated power of the shared PV 2 and receives data indicating the measurement result. Then, the center server 20 calculates the power generation amount (strictly, generated power) of the shared PV 2 per predetermined time based on the measurement result of the power sensor E7. Incidentally, the measurement result data of the power sensor E7 corresponds to the power generation amount data related to the power generation amount of the shared PV2. Therefore, it can be said that the center server 20 that receives the measurement result data from the power sensor E7 corresponds to a power generation amount data acquisition device.

  Further, the center server 20 communicates with a power sensor E8 that measures the power transmitted to the storage battery 8 installed in the mobility station C, and receives data indicating the measurement result. Then, the home server 10 calculates the current storage amount of the storage battery 8 based on the measurement result data of the power sensor E6 that measures the power consumption of the mobility station C and the mobility 3, and the measurement result data of the power sensor E8. To do.

  In addition, about the area whole area power consumption calculated by the center server 20, the power generation amount of the common PV2, and the power storage amount of the storage battery 8, the calculation result is distributed to each house H in the specific area AR. ing. That is, the home server 10 of each house H obtains the calculation result of the entire area power consumption and the like through communication with the center server 20. The home server 10 displays the obtained calculation result on the user terminal 11. Thereby, the residents of each house H can check the calculation result of the entire area power consumption and the like (in other words, the supply and demand situation of the entire specific area AR) through the user terminal 11.

  Furthermore, the center server 20 is provided with a point distribution function in addition to the power supply and demand aggregation function described above. The point distribution function is a function for converting the profit obtained by selling the generated power of the shared PV 2 into points and allocating it to each house H in the specific area AR. In this sense, it can be said that the center server 20 corresponds to a point providing device that distributes and gives points to each house H in the specific area AR.

  Explaining the general flow of point allocation, the center server 20 communicates with the power company server 30 owned by the power company K1 through the external network GN, and the amount according to the power purchased by the power company K1 within a predetermined period (that is, , Data indicating the power sales revenue). The center server 20 identifies the power sales revenue from the received data, and converts the identified power sales revenue into points at a constant conversion rate. Thereafter, the center server 20 distributes the converted points to each house H in the specific area AR.

  Note that the points owned by each house H are stored for each house H by the point storage database 20x of the center server 20. That is, the point storage database 20x corresponds to a point storage device, and stores points for each house H. More specifically, as shown in FIG. 4, the point storage database 20x assigns points by house H to information (specifically, name and occupancy date) about the residents of the house H and the house H. It is stored in association with identification information (server identification ID) of the installed home server 10. FIG. 4 is a diagram showing points stored in the point storage database 20x for each house H, strictly, a point storage table.

  Explaining the points, the residents of each house H can receive the service provided by the service providing company K2 by using the points they own. That is, the service provided by the service providing company K2 can be used in exchange for points, and in this embodiment, the management service for equipment used in the house H and the repair service for the house H are applicable. To do. “Management service for equipment used in house H” means that equipment used in house H (for example, kitchen range, air conditioner, bathtub, toilet, etc.) is cleaned and inspected, and consumables in the equipment are removed. It is a service to exchange. Further, the “repair service for the house H” is a service for performing repair work for each part of the house H.

  As described above, in the present system S, the power sale revenue obtained by selling the power generated by the shared PV 2 is used to maintain the living environment of each house H in the specific area AR. . That is, the residents of each house H can receive maintenance of the living environment at home as a benefit of the power generated by the shared PV 2 while realizing environmentally conscious power supply and demand through the system S corresponding to CEMS. .

  The services that can be used in exchange for points are not limited to the above-described services (that is, the management service for equipment used in the house H and the repair service for the house H). Any service other than those described above may be used as long as it is a service necessary to maintain the living environment of the house H.

The point update unit 210 increases or decreases the points stored in the point storage database 20x when the points are newly allocated by the distribution process or when the points are consumed in accordance with the service application. The process to update to (hereinafter, update process) is executed. The point notification unit 211 executes a process of notifying the residents of the house H whose points have been updated in the update process (hereinafter referred to as a notification process).

  Hereinafter, in order to describe in detail the processing executed by each function unit related to point management, a point distribution flow realized by cooperation of the above function units will be described with reference to FIG. FIG. 12 is a diagram showing the flow of the point distribution flow.

  In this system S, the point allocation flow is to be repeated every year. That is, in the center server 20, the function unit related to point management executes a series of processes related to the point allocation flow according to FIG. 12 every year on a predetermined day (hereinafter referred to as allocation execution date) (S001).

  When the point distribution flow is executed, first, the power sale revenue specifying unit 206 executes a revenue specifying process (S002). In this process, the power sale revenue specifying unit 206 communicates with the power company server 30 and receives power sale revenue data from the power company server 30. The “power sales revenue data” is data indicating revenue obtained by selling the generated power of the shared PV 2 for one year from the allocation execution date of the previous year to the allocation execution date of this year. Then, the power sales revenue specifying unit 206 specifies the power sales revenue for one year from the power sales revenue data.

  Next, conversion processing by the point conversion unit 207 is executed, and the power sales revenue specified in the previous step S002 is converted into points (S003). Thereafter, the distribution process by the point distribution unit 208 is executed, and the points converted from the power sales revenue in the previous step S003 are distributed to each house H in the specific area AR (S004). In this process, points are allocated to each house H based on the evaluation result of the power saving degree of each house H evaluated by the house-specific power saving degree evaluation unit 205.

  Specifically, according to the ranking result of the power saving degree performed by the house-specific power saving degree evaluation unit 205 in the evaluation process, privilege points are given to the houses H in the ranks up to the top N. The houses H in the ranks up to the top N are given points that are added by the amount of the privilege points as compared to the houses H in the subsequent ranks. As described above, in the present system S, points are allocated according to the degree of power saving when points are allocated. Thereby, it becomes possible to improve the consciousness of the residents of each house H with respect to power saving.

  After the execution of the distribution process S004, a summation process (S007) by the point summation unit 209, an update process (S008) by the point update unit 210, and a notification process (S009) by the point notification unit 211 are executed. These processes are to be executed for each house H. More specifically, the point summation unit 209 performs summation processing for each house H. At this time, the point summation unit 209 specifies the number of years elapsed from the occupancy date of the residents of each house H. This elapsed year can be specified from the occupancy date of the residents of each house H stored together with the points in the point storage database 20x.

  And about the house H whose elapsed years from the occupancy date are not 5m + 1 year (m is a natural number of 1 or more) (No in S005), a normal summing process is performed after that. That is, the points stored in the point storage database 20x immediately before the execution of the distribution process and the points newly allocated by the execution of the distribution process are added together for each house H. On the other hand, for the house H whose age from the move-in date is 5m + 1 (Yes in S005), the points stored in the point storage database 20x at that time are cleared (S006), and the summing process is performed after the points are cleared. Execute. That is, the points can be carried over to a maximum of 5 years, and the points that have been held until then will be forcibly disappeared in the 5m + 1 year from the move-in date. However, the present invention is not limited to this, and the holding points may be permanently held. Moreover, it is possible to arbitrarily set the timing for clearing (forcibly annihilating) the possession points.

  After execution of the summation process, an update process is executed. In the update process, the point update unit 210 sets the object of the summation process in the previous step S007 among the points for each house H stored in the point storage database 20x. We update point of house H that became. Specifically, the summation result in the summing process is newly stored in the point storage database 20x as the point of the house H that is the subject of the summing process.

  Then, a notification process is executed after the update process is executed, and in the notification process, the point notification unit 211 notifies the updated point to the house H that holds the point that is the update target in the previous step S008. To do. Specifically, data indicating the point after the update is generated, and the data is stored in the home server 10 in the house H that holds the point to be updated (that is, the identification ID associated with the point to be updated). To the home server 1) indicated by Thereby, the residents of the house H can check the updated points on the information display screen displayed on the display of the user terminal 11, specifically on the service application screen.

  Thereafter, when the steps (S005 to S009) after the distribution process are repeated for all the houses H in the specific area AR (S010), the point distribution flow for that year ends. When the next year's distribution execution date is reached, the point distribution flow is executed again, and the above-described series of processing is executed. Note that the evaluation process by the house-specific power saving degree evaluation unit 205 is also executed at one-year intervals together with the point distribution flow. Thereby, at the time of point allocation, it becomes possible to allocate points reflecting the latest power saving degree (specifically, ranking of power saving degree) in each house H.

<< About management flow in each house H >>
Next, a flow of management performed in each house H in the specific area AR in the system S will be described. In the management flow in each house H described below, the power generation facility management method of the present invention is adopted. If it demonstrates concretely, the process which comprises the power generation equipment management method of this invention will be implemented as a management flow in each house H, More specifically, it is embodied as the following four management flows F1-F4. ing.
(F1) Home power supply / demand confirmation flow (F2) Area-wide power supply / demand confirmation flow (F3) Point confirmation / service application flow (F4) Usage switching flow

  Hereinafter, each management flow will be described individually. In the following, for easy understanding, the management flow in the house H of Mr. A corresponding to one house H among the plurality of houses H in the specific area AR will be described as an example. To do.

(Home electricity supply and demand confirmation flow)
The flow for confirming the supply and demand of home electricity is the power supply and demand situation in Mr. A's house H, specifically, the power load in the house, the amount of power generation of the PV1 on the house side installed in Mr. A's house H, and Mr. A's house H It is the management flow which confirms the electrical storage amount of the installed storage battery. In this flow, the home server 10 and the user terminal 11 in Mr. A's house H cooperate to execute each process according to the flow illustrated in FIG. FIG. 13 is a diagram illustrating a flow of a home power supply / demand confirmation flow.

  Specifically, in the home power supply / demand confirmation flow, first, a home power supply / demand confirmation screen is drawn on the display of the user terminal 11 (S101). On the other hand, the home server 10 communicates with the power sensors E1 to E5 through the home network TN and acquires measurement result data of each sensor (S102). Then, the home server 10 analyzes and tabulates the acquired measurement result data, “information according to power consumption in the house H”, “information according to the power generation amount of the house side PV1”, and “current time of the storage battery 7”. "Information according to the amount of stored electricity" is identified (S103). The identification of these pieces of information is performed by the above-described housing-side power consumption information display unit 102, the housing-side power storage amount display unit 103, and the house-side power generation amount display unit 104.

  After the information specifying step S103 is completed, the home server 10 displays the information specified in the information specifying step S103 on the home power supply / demand confirmation screen drawn on the display of the user terminal 11 (S104). As a result, the information shown in FIG. 6, that is, the information regarding the power supply and demand situation in Mr. A's house H is displayed on the display of the user terminal 11 of Mr. A. And A can grasp | ascertain the electric power supply-and-demand situation at home by seeing the display of the state where the said information was displayed.

(Overall area power supply / demand confirmation flow)
The entire area power supply / demand confirmation flow is a management for confirming the power supply / demand situation of the entire specific area AR, specifically, the entire area power consumption, the amount of power generated by the shared PV2, and the amount of electricity stored in the storage battery 8 provided in the mobility station C. It is a flow. In this flow, the home server 10 and the user terminal 11 in Mr. A's house H cooperate to execute each process according to the flow illustrated in FIG. FIG. 14 is a diagram showing the flow of the entire area power supply and demand confirmation flow.

  More specifically, in the overall area power supply and demand confirmation flow, first, an overall area power supply and demand confirmation screen is drawn on the display of the user terminal 11 (S201). On the other hand, the home server 10 communicates with the center server 20 through the external network GN and receives data indicating the power consumption of the entire area, data indicating the power generation amount of the shared PV2, and data indicating the current power storage amount of the storage battery 8. (S202). Then, the home server 10 analyzes and aggregates various data received from the center server 20, and “information according to the power consumption of the entire area”, “information according to the power generation amount of the shared PV 2”, and “current time of the storage battery 8”. "Information according to the amount of stored electricity" is specified (S203). The identification of these pieces of information is performed by the common unit power generation amount information display unit 105, the common unit power storage amount information display unit 106, and the entire area power consumption information display unit 107 described above.

  After the information specifying step S203 is completed, the home server 10 displays the information specified in the information specifying step S203 on the entire area power supply / demand confirmation screen drawn on the display of the user terminal 11 (S204). As a result, the information shown in FIG. 7, that is, the information regarding the power supply / demand situation of the entire specific area AR is displayed on the display of the user terminal 11 of Mr. A. Then, by looking at the display in a state where the information is displayed, Mr. A can grasp the power supply and demand situation in the area where he lives (that is, the specific area AR).

(Point confirmation / service application flow)
The point confirmation / service application flow confirms the point that Mr. A currently holds (in other words, the point of Mr. A's house H out of the points stored in the point storage database 20x), and the point This is a management flow for applying for a service using. This flow is performed only for a certain period thereafter when the point distribution flow is performed on the center server 20 side every year. That is, Mr. A and the residents of each house H in the specific area AR apply for a service during a certain period from the point update point (more precisely, when points are newly allocated). As described above, the service application period is limited to a certain period from the point when the points are updated, so that it is possible to encourage residents to use the points, that is, to use the services. As a result of promoting the use of the service, the living environment of each house H is appropriately maintained, and the living environment is improved at the local level.

  In the point confirmation / service application flow, the home server 10 and the user terminal 11 in Mr. A's house H cooperate to execute each process according to the flow shown in FIG. FIG. 15 is a diagram showing the flow of the point confirmation / service application flow.

  More specifically, this flow starts with the home server 10 (or the user terminal 11) confirming the date of the current day (S301). Then, if the date of the current day is within the period until the predetermined number of days elapses from the implementation date of the point allocation flow performed immediately before, that is, within the first application period (Yes in S302), the date of the user terminal 11 is displayed. A management service application screen is drawn (S303).

  On the other hand, when the date of the day is not within the first application period (No in S302), the home server 10 (or the user terminal 11) indicates the number of years that have passed since Mr. A moved into his / her house H (number of years of occupancy). Identify. And the occupancy is 5m years (m is a natural number of 1 or more) (Yes in S304), and the date of the day is the period from the expiration date of the first application period until the predetermined number of days elapses, that is, If it is within the second application period (Yes in S305), a repair service application screen is drawn on the display of the user terminal 11 (S306).

  If the current date is not within the first application period and the occupancy is not 5 m years (No in S304), or if it is not within the second application period (No in S305), this flow is The process ends (S312).

  When the management service application screen or the repair service application screen is drawn, the home server 10 communicates with the center server 20 through the external network GN, and receives data indicating the respective points from the center server 20 (S307). Thereafter, the home server 10 identifies the current value of the points owned by Mr. A's house H from the received data indicating the respective points, and displays the identification result on the application screen (S308). Such a step is performed by the point display unit 110 described above.

  By performing the above steps, the application screen in which the current value of the points owned by Mr. A's house H is displayed on the display of Mr. A's user terminal 11 as shown in FIG. 9 or 10. Will be projected. Through the application screen in such a state, Mr. A designates a desired service from among the services shown on the application screen while looking at the current value of his / her possession points.

  When Mr. A performs a service application operation through the application screen (S309), the home server 10 (strictly, the application reception unit 111 described above) receives the application operation (S310). Thereafter, the home server 10 (strictly, the service ordering unit 112 described above) generates ordering data indicating the contents of the application operation, and transmits the ordering data to the service providing company server 40 (S311). As a result, Mr. A applies for a desired service using the possession points, and receives the service at a later date.

  In the system S, as described above, the services that A can apply for are changed according to the number of years of occupancy. Specifically, services related to maintenance work that is performed relatively frequently in the house H, such as cleaning and replacement of consumables, that is, management services for equipment used in the house H can be applied every year. Is possible. On the other hand, it is possible to apply for the repair service of the house H performed once every several years only once every five years. Thus, by changing the service that can be applied according to the number of years of occupancy, the points can be utilized more effectively in maintaining the living environment of the house H.

(Application switching flow)
The use switching flow is a management flow for switching the use of the generated power of the house side PV1 installed in Mr. A's house H. In this flow, the home server 10 and the user terminal 11 in Mr. A's house H cooperate to execute each process according to the flow illustrated in FIG. FIG. 16 is a diagram showing the flow of the usage switching flow.

  Specifically, in the usage switching flow, first, the selection screen illustrated in FIG. 8 is drawn on the display of the user terminal 11 (S401). Then, when Mr. A performs a use selection operation through the selection screen (S402), the home server 10 (strictly, the selection receiving unit 108 described above) receives the selection operation (S403). Thereafter, the home server 10 (strictly speaking, the above-described use switching unit 109) controls a changeover switch or the like provided in the power supply line in the house H according to the content of the selection operation. Thereby, the use of the generated power of the house side PV1 is switched to the use selected by Mr. A (S404).

  By switching the use of the generated power of the residential PV1 by the above procedure, Mr. A changes the use appropriately according to the situation at the time (for example, fluctuations in the amount of electricity purchased or purchased in the house). It becomes possible to do.

<< Effectiveness of System S >>
As described above, according to the present system S, in each house H in the specific area AR, information according to the power generation amount of the house-side PV1 installed at home, information according to the generated power of the shared PV2, The current value of each point when the profit obtained by selling the generated power of the shared PV 2 is converted into points and allocated to each house H is displayed on the display of the user terminal 11. The display of the user terminal 11 displays a screen for applying for services that can be used in exchange for points, and further displays a selection screen for selecting the use of the generated power of the residential PV1. Is done. Then, the home server 10 and the user terminal 11 of each house H receive a service application operation performed through the application screen and a use selection operation performed through the selection screen.

  With the above configuration, the residents of each house H who are users of the present system S use their home server 10 and user terminal 11 to check the power generation status of the house-side PV1 and the shared PV2, and the current possession points. It becomes possible to collectively check the value, apply for the service, and select the usage of the power generated by the residential PV1. As a result, the present system S is convenient for the residents of each house H in the specific area AR. In addition, for the residents of each house H, it is possible to more easily perform the above-described confirmation work and application / selection actions.

  Furthermore, in this system S, the power sales revenue when selling the generated power of the shared PV 2 (strictly, the points of each house H when the power sales revenue is converted into points and allocated to each house H) is It can be exchanged for a service for maintaining and managing the living environment in the housing H in the specific area AR. That is, the residents living in the houses in the specific area AR can realize the power supply and demand in consideration of the environment, and can use the profits obtained thereby for the maintenance management of the home living environment. As a result, it is possible to achieve both a reduction in environmental load in the specific area AR and an extension of the life of the house H in the same area.
