It is a flowchart which shows an example of the procedure of the electric power management method which concerns on one Embodiment.

As shown in FIG. 1, the power management system 100 according to the embodiment includes a power management device 20, a transaction meter 21, a dwelling unit meter 22, a shared load 41, and a dwelling unit load 42. At least a part of the power management system 100 may be installed in an apartment house.

Apartment houses may be in various forms such as condominiums, apartments, or maisonettes. The housing complex may be managed by the management entity. The management entity of the housing complex may be the owner of the housing complex or the business operator who manages the housing complex. The management entity of the housing complex may individually conclude a occupancy contract with the resident of each dwelling unit.

The shared load 41 is a power load provided in a common portion of an apartment house. The common area may be, for example, a corridor or stairs of an apartment house. The shared load 41 may include equipment provided in the common portion, for example, lighting equipment such as an outdoor light, emergency equipment such as a septic tank blower power supply, a fire alarm, and other equipment such as air conditioning equipment. The dwelling unit load 42 is a power load provided in each dwelling unit of an apartment house, and may be, for example, an electric device such as a lighting fixture, a refrigerator, a television, or an air conditioner used in each dwelling unit. Apartment houses include multiple dwelling units. That is, the power management system 100 includes a plurality of dwelling unit loads 42.

The transaction meter 21 is connected between the power grid 50 and the shared load 41 and the dwelling unit load 42. The transaction meter 21 measures the total electric energy of the electric energy supplied from the electric power grid 50 to the shared load 41 and the electric energy supplied from the electric power grid 50 to each dwelling unit load 42. The dwelling unit meter 22 is connected to each dwelling unit load 42, and is connected to the power grid 50 via the transaction meter 21. The dwelling unit meter 22 measures the amount of electric energy supplied from the power grid 50 to each dwelling unit load 42.

The power management device 20 is connected to the transaction meter 21 and the dwelling unit meter 22 by the communication line represented by the broken line, and acquires the measurement results of the transaction meter 21 and the dwelling unit meter 22.

The power management device 20 may include a device such as a server. The power management device 20 may include at least one processor to provide control and processing power to perform various functions. The processor can execute a program that realizes various functions of the power management device 20. The processor may be implemented as a single integrated circuit. The integrated circuit is also called an IC (Integrated Circuit). The processor may be implemented as a plurality of communicably connected integrated circuits and discrete circuits. The processor may be implemented on the basis of various other known techniques.

The power management system 100 may further include a distributed power source 60. The distributed power source 60 may be installed in an apartment house. The distributed power source 60 includes a power conditioner (hereinafter, also referred to as PCS) 61 and a solar cell (hereinafter, also referred to as PV) 62.

The PCS61 may include an inverter, a converter, or the like. The PCS61 converts the DC power output by the PV 62 into AC power or converts it into DC power having a different voltage. The PCS61 outputs the converted power. The PCS 61 is connected to a node located on the path where the transaction meter 21, the shared load 41, and the dwelling unit load 42 are connected. The PCS 61 is connected to the power grid 50 via a trading meter 21. The PCS 61 is connected to each dwelling unit load 42 via a dwelling unit meter 22. The PCS 61 may supply the converted power to the shared load 41. The PCS 61 may supply the converted electric power to the dwelling unit load 42. The dwelling unit meter 22 can measure the total electric energy of the electric energy supplied by the PCS 61 to the dwelling unit load 42 and the electric energy supplied by the power grid 50 to the dwelling unit load 42. The PCS 61 may reverse-feed the surplus power out of the converted power to the power grid 50. The surplus power corresponds to the power that exceeds the total power consumed by the shared load 41 and the dwelling unit load 42 among the power output by the PCS 61. The transaction meter 21 measures the amount of power supplied by the power grid 50 to the shared load 41 and the dwelling unit load 42, and also measures the amount of power that the PCS 61 reverse power flows into the power grid 50.

The PV62 is not limited to solar cells, and may be replaced with a power source based on other renewable energy such as a power source generated by wind power. The PV62 may be replaced with a configuration that includes a power source based on multiple types of renewable energy. The PV62 may be replaced by another power source such as a fuel cell or a power storage device. PV62 may be combined with a power storage device. The PV62 may be replaced with a configuration that combines a power source based on renewable energy and a power storage device.

The number of each of PCS61 and PV62 is not limited to one, and may be two or more. For example, the PV62 may be divided into the roof of an apartment house, the roof of a parking lot of an apartment house, the site of an apartment house, or the like.

The power management device 20 may be connected to the PCS 61 by a communication line represented by a broken line. The power management device 20 acquires the amount of power output by the distributed power source 60 from the PCS 61.

The electric power company concludes a collective power receiving contract with the management entity of the apartment house. The electric power company supplies electric power from the electric power grid 50 to the apartment house based on the collective power receiving contract. The shared load 41 and the dwelling unit load 42 provided in the apartment house consume the power received collectively. The transaction meter 21 measures the amount of electric power that the apartment house collectively receives from the electric power grid 50. The transaction meter 21 may be a certified watt hour meter. A watt-hour meter with certification is also called a certification meter. The electric power company manages the transaction meter 21 and acquires the measurement result from the transaction meter 21. Based on the measurement result, the electric power company calculates the electricity charge corresponding to the amount of electric energy collectively received by the apartment house from the electric power grid 50. The electric power company charges the management entity of the apartment house with the electricity charge calculated based on the measurement result of the transaction meter 21.

When the management entity of an apartment house concludes a collective power reception contract, either a high-voltage collective power reception contract or a low-voltage collective power reception contract is selected. A high-voltage batch power reception contract is a contract for batch power reception with an electric capacity equal to or higher than a predetermined value. A low-voltage batch power reception contract is a contract for batch power reception with an electric capacity less than a predetermined value. The predetermined value is appropriately determined by the electric power company. The predetermined value may be, for example, 50 kW or the like. The management entity of the apartment house may conclude either a high-voltage collective power receiving contract or a low-voltage collective power receiving contract based on the number of units in the apartment house.

If a high-voltage collective power reception contract is signed, it may be necessary to install high-voltage power receiving equipment such as cubicles, or to appoint a security manager such as a chief electrical engineer, while the unit price of electricity will be high. Can be reduced. When the number of apartments is small, the electricity demand of the apartment as a whole may be less than the specified value. If the power demand of the apartment house as a whole remains below a predetermined value, the management entity of the apartment house may conclude a low-voltage collective power receiving contract. If a low-voltage collective power reception contract is signed, it is not necessary to install high-voltage power receiving equipment and appoint a security manager such as a chief electrical engineer. That is, the burden of the cost of installing the high-voltage power receiving equipment and appointing the security manager is avoided. Regardless of whether a high-voltage collective power reception contract or a low-voltage collective power reception contract is concluded, it is possible to realize a peak cut in power consumption by leveling the power consumption of the entire apartment building. As a result, regardless of whether a high-voltage collective power reception contract or a low-voltage collective power reception contract is concluded, the management entity or resident of the housing complex is more likely to be the management entity or resident than when the resident individually concludes a power reception contract with the electric power company. You can enjoy the benefits of reducing the unit price of electricity.

In the present embodiment, it is assumed that the management entity of the apartment house has a low-voltage collective power receiving contract with the electric power company. In this case, the shared load 41 and the dwelling unit load 42 receive power under a low-voltage collective power receiving contract. The power consumed in the entire housing complex can be leveled by the variation in the pattern of power consumption in each dwelling unit load 42. The variation in the power consumption pattern in each dwelling unit load 42 may be due to the difference in the living pattern of each dwelling unit. For example, the power consumed by a dwelling unit where residents often go out in the daytime may be low in the daytime and high in the nighttime. On the other hand, there may be dwelling units that consume less electricity at night. When the housing complex is provided with the distributed power source 60, the shared load 41 and the dwelling unit load 42 may receive electric power from the distributed power source 60. By leveling the power consumption, the shared load 41 and the dwelling unit load 42 can constantly consume the power from the distributed power source 60. When the fluctuation range of the power consumption is large, the time zone in which the surplus power is generated may be longer than when the fluctuation range of the power consumption is small. Due to the generation of surplus power, the self-consumption rate of the power output by the distributed power source 60 becomes low. If the fluctuation range of power consumption is small, the time zone in which surplus power is not generated may be long. Since the surplus power is not generated, the self-consumption rate of the power output by the distributed power source 60 becomes high. In other words, leveling power consumption can increase the self-consumption rate.

The management entity of the housing complex collects electricity charges from the residents of each dwelling unit in order to pay the electricity charges to the electric power company. In the present embodiment, the management entity of the housing complex charges the resident of each dwelling unit a fixed electricity charge regardless of the power consumption of the dwelling unit load 42 of each dwelling unit. That is, the management entity of the apartment house charges the resident of the dwelling unit who uses each dwelling unit load 42 a fixed amount of electricity charges which is not based on the amount of electric energy supplied to each dwelling unit load 42. A flat-rate electricity charge that is charged not based on the power consumption of the dwelling unit load 42 is also called a flat-rate charge.

If the management entity of the housing complex charges the resident of each dwelling unit for the electricity charge based on the power consumption of the dwelling unit load 42, the meter reading work of the dwelling unit meter 22 occurs every month. The electricity charge charged based on the power consumption of the dwelling unit load 42 is also called a metered charge. If pay-as-you-go is charged, the amount charged to the resident is likely to vary from month to month. The load of the work of charging different amounts is greater than the load of the work of charging a fixed amount. Billing of a flat rate can realize omission of meter reading work and reduction of the load of billing work.

In the present embodiment, the distributed power source 60 may be connected to at least a part of the dwelling unit load 42. In other words, the distributed power source 60 may be provided in at least some dwelling units. The distributed power source 60 may be installed in different situations in each dwelling unit. By charging a flat rate to the resident of each dwelling unit having the dwelling unit load 42, the resident of each dwelling unit can use the distributed power source 60 regardless of whether or not the dwelling unit load 42 is connected to the distributed power source 60. You can enjoy the benefits of reducing electricity charges fairly.

When a flat rate is charged as an electricity rate, the power consumption of the dwelling unit load 42 tends to increase as the resident uses a device that consumes electricity without worrying about the electricity rate. In this case, the power consumption of each dwelling unit load 42 tends to be higher than that in the case where the metered rate is charged. The pay-as-you-go rate corresponding to the increased power consumption can be higher than the flat rate. When the metered rate corresponding to the power consumption of each dwelling unit load 42 exceeds the fixed rate, the management entity of the apartment house needs to compensate for the difference in the electricity rate. However, simply raising the flat rate can increase the burden on residents and cause a decline in the occupancy rate.

The flat rate may be determined based on the estimated amount of the power sale price of the power that is reversely flowed from the distributed power source 60 to the power grid 50. The flat rate may be determined so that the difference between the metered rate corresponding to the power consumption of each dwelling unit load 42 and the flat rate is smaller than the power sale price.

One of the plurality of dwelling unit loads 42 is referred to as a first dwelling unit load. The power management device 20 determines the magnitude of the incentive given to the resident of the dwelling unit in which the first dwelling unit load is provided when the power consumption of the first dwelling unit load becomes equal to or less than the first electric energy amount. You may calculate. That is, an incentive may be generated when the power consumption of the load of the first dwelling unit becomes equal to or less than the first power consumption. In this way, the power management system 100 can motivate the resident to reduce the power consumption. As a result, the metered rate corresponding to the power consumption of each dwelling unit load 42 is less likely to exceed the flat rate. By preventing the metered rate corresponding to the power consumption of each dwelling unit load 42 from exceeding the flat rate, it is possible to avoid raising the flat rate. By not raising the flat rate, it is possible to avoid an increase in the burden on residents and a decrease in the occupancy rate. When an incentive is generated on the condition that the power consumption of the load of the first dwelling unit is equal to or less than the first power amount, the management entity of the apartment house gives the resident, for example, 200 kWh of power consumption per month. It can be explained that the incentive is given by the following. By doing so, the conditions for generating incentives can be easily communicated to the residents. The power management device 20 may calculate the magnitude of the incentive when the power consumption of the first dwelling unit load is less than the first power amount.

Incentives may be given as cash or electronic money, or as points that can be exchanged for valuable resources or paid services. When the incentive is given as cash, the amount equivalent to the incentive may be transferred to the resident's bank account or credit account. When the incentive is given as points, the points may be given in the point service to which the resident subscribes. When the incentive is given as electronic money, the electronic money corresponding to the incentive may be given in the electronic money service to which the resident subscribes.

The magnitude of the incentive given to the resident of the dwelling unit provided with the first dwelling unit load may be determined based on the difference between the first electric energy amount and the power consumption amount in the first dwelling unit load.

The power management device 20 is imposed on the resident of the dwelling unit provided with the first dwelling unit load when the power consumption of the first dwelling unit load exceeds the second electric energy larger than the first power amount. Penalty may be calculated. In this way, the power management system 100 can motivate the resident to avoid an increase in power consumption. As a result, the metered rate corresponding to the power consumption of each dwelling unit load 42 is less likely to exceed the flat rate. By preventing the metered rate corresponding to the power consumption of each dwelling unit load 42 from exceeding the flat rate, it is possible to avoid raising the flat rate. By not raising the flat rate, it is possible to avoid an increase in the burden on residents and a decrease in the occupancy rate. When a penalty is generated on the condition that the power consumption of the load of the first dwelling unit exceeds the second power amount, the management entity of the apartment house tells the resident, for example, the power consumption of one month is 400kWh or less. It can be explained that the penalty can be avoided by setting. By doing so, the conditions for avoiding the penalty can be easily communicated to the resident.

Penalties may be imposed by cash or electronic money, or by points. If the penalty is imposed in cash, the amount equivalent to the penalty may be deducted from the resident's bank account, credit account, etc. If a penalty is imposed by points, the points may be deducted from the points service to which the resident subscribes. If the penalty is imposed by electronic money, the electronic money equivalent to the penalty may be deducted from the electronic money service to which the resident subscribes.

The magnitude of the penalty imposed on the resident of the dwelling unit provided with the first dwelling unit load may be determined based on the difference between the power consumption amount and the second electric energy amount in the first dwelling unit load.

As shown in the graph of FIG. 2, the power consumption in the first dwelling unit load may be divided into three patterns based on the magnitude relationship between the first power amount and the second power amount. In the graph of FIG. 2, the horizontal axis represents the distinction between patterns. The vertical axis represents the amount of power consumption. The height of the bar graph represents the power consumption in each pattern. The power consumption in each pattern is represented by P. It is assumed that the first electric energy and the second electric energy are represented by P1 and P2, respectively.

In the A pattern, the power consumption P in the load of the first dwelling unit is smaller than the first power consumption P1. In this case, the power management device 20 calculates the difference between P1 and P. The difference between P1 and P corresponds to the power consumption reduced by the resident of the dwelling unit in which the first dwelling unit load is provided, and is represented by R. The power management device 20 may calculate the magnitude of the incentive given to the resident of the dwelling unit provided with the first dwelling unit load based on the value of R.

In the B pattern, the power consumption P in the load of the first dwelling unit is the first power amount P1 or more and the second power amount P2 or less. In this case, the power management device 20 may notify the resident of the dwelling unit in which the first dwelling unit load is provided that the power consumption is within the predetermined range, and both incentives and penalties are provided. You may notify that it did not occur. The first electric energy and the second electric energy may be recognized by the resident as the standard electric energy of the dwelling unit load 42.

In the C pattern, the power consumption P in the load of the first dwelling unit is larger than the second power consumption P2. In this case, the power management device 20 calculates the difference between P and P2. The difference between P and P2 corresponds to the amount of power consumed by the resident of the dwelling unit in which the first dwelling unit load is provided, and is represented by E. The power management device 20 may calculate the penalty imposed on the resident of the dwelling unit in which the first dwelling unit load is provided, based on the value of E.

The magnitude of the incentive may be determined based on a value obtained by multiplying the difference between the first electric energy and the power consumption in the first dwelling unit load by the first coefficient. For example, as the first coefficient, the unit price of nighttime electricity when the electricity rate fluctuates depending on the time zone may be used. The contract in which the electricity rate fluctuates depending on the time zone may be a contract provided by the electric power company, and is also referred to as, for example, a time zone lamp. When the first coefficient is expressed as C1, the power management device 20 calculates the magnitude of the incentive given to the resident of the dwelling unit in which the first dwelling unit load is provided, based on the value of R × C1. You can.

The magnitude of the penalty may be determined based on the value obtained by multiplying the difference between the power consumption amount and the second power consumption amount in the first dwelling unit load by the second coefficient. For example, as the second coefficient, the unit price of daytime electricity when the electricity rate fluctuates depending on the time zone may be used. When the second coefficient is expressed as C2, the power management device 20 may calculate the penalty imposed on the resident of the dwelling unit in which the first dwelling unit load is provided, based on the value of E × C2.

When the unit price of daytime power is higher than the unit price of nighttime power, the second coefficient is made larger than the first coefficient. By making the second coefficient larger than the first coefficient, the behavior of the resident can be changed so as to lead to a reduction in power consumption.

The unit price of electricity is not limited to the time of day, and may be determined based on various other conditions. The unit price of electric power may be determined based on, for example, the magnitude of the amount of electric power used. The larger the amount of electric power used, the higher the unit price of electric power may be. The unit price of electricity may be determined based on, for example, the seasons of spring, summer, autumn, and winter. The electric power unit price may be determined based on, for example, the amount of power generated by PV62. As the first coefficient, the cheapest unit price among the electricity charges that fluctuate under various conditions may be used. By doing so, the size of the incentive is determined so that the incentive is within the range of the profit from the reduction of electricity charges based on the reduction of power consumption. As the second coefficient, the highest unit price among the electricity charges that fluctuate under various conditions may be used. In this way, the magnitude of the penalty is determined so that the penalty can cover the loss due to the increase in electricity charges due to the increase in power consumption. As a result, when the power consumption in each dwelling unit load 42 is greatly reduced or greatly increased, the loss for the management entity of the apartment house is less likely to occur.

The electric power management device 20 gives the resident the magnitude of the incentive or the resident at the timing when the management entity of the housing complex gives the resident an incentive or imposes a penalty. You may calculate the magnitude of the penalty you impose. The management entity of the apartment house gives an incentive or a penalty to the resident based on the calculation result of the power management device 20.

The management entity of the housing complex may give incentives or impose penalties when the resident moves out of the dwelling unit. By doing so, the management entity of the housing complex can surely execute the incentive or the imposition of the penalty. The management entity of the housing complex may include incentives or penalties in the amount to be settled at the time of moving out. If the resident is given an incentive when he / she leaves the residence, the management entity of the housing complex may increase the refund amount of the security deposit. If the resident is penalized when he / she leaves the residence, the management entity of the housing complex may reduce the refund amount of the security deposit.

The management entity of the housing complex may give incentives or impose penalties when the resident renews the residence contract. By doing so, the period from when the conditions for giving incentives and imposing penalties are satisfied to when they are actually executed is shortened. The period from the establishment of the incentive or penalty occurrence condition to the execution is also called the unsettled period. Shortening the unsettled period reduces the amount of reserves recorded for unsettled incentives on the books and the amount of uncollected funds recorded for unsettled penalties. As a result, it becomes easier for the management entity of the housing complex to manage the books. Reducing the unpaid period can increase the likelihood that the resident will remember the reason for the incentive or penalty. As a result, residents are more likely to be convinced that incentives and penalties will be imposed. If the resident gives an incentive to the resident at the timing of renewing the residence contract, the management entity of the housing complex may reduce the renewal fee. If the resident imposes a penalty on the resident at the timing of renewing the residence contract, the management entity of the housing complex may increase the renewal fee.

The electric power management device 20 may calculate the magnitude of the incentive or the penalty at a predetermined timing until the timing when the management entity of the housing complex gives an incentive or imposes a penalty on the resident. .. The predetermined timing may be, for example, every one month or every two months. The predetermined timing may be set as appropriate. The power management device 20 adds up the incentives or penalties calculated up to that point when it is time for the management entity of the housing complex to give incentives or impose penalties on the residents. Good. The management entity of the housing complex may give an incentive or impose a penalty on the resident based on the magnitude of the incentive or penalty added by the power management device 20. The power management device 20 may notify the resident of the magnitude of the incentive or penalty calculated at a predetermined timing. The power management device 20 can make the resident more aware of the reduction of the power consumption by calculating the magnitude of the incentive or the penalty at a predetermined timing. As a result, resident behavior can change to reduce power consumption.

The power management device 20 may execute a power management method including the procedure shown in the flowchart of FIG. 3 as an example. The power management method may be executed by the processor included in the power management device 20 as a power management program.

The power management device 20 sets the first coefficient and the second coefficient, and the first electric energy amount and the second electric energy amount (step S1). The first coefficient and the second coefficient are also simply referred to as coefficients. The first electric energy and the second electric energy are collectively referred to as a reference electric energy.

The power management device 20 acquires the meter display value at the time of reference (step S2). The reference time may include the timing when the resident moves into the dwelling unit. The reference time may include the timing when the resident renews the residence contract. The reference time may include the timing when the management entity of the housing complex gives an incentive or a penalty to the resident. The reference time is not limited to these examples, and may include various timings. The meter display value at the reference time corresponds to the value of the cumulative power consumption measured by the dwelling unit meter 22 up to the reference time.

The power management device 20 acquires the meter display value at the time of settlement (step S3). The settlement may include the timing of the resident moving out of the residence. The settlement may include the timing when the resident renews the residence contract. The settlement time is not limited to these examples and may include various timings. The meter display value at the time of settlement corresponds to the value of the cumulative power consumption measured by the dwelling unit meter 22 at the time of settlement.

The power management device 20 calculates the power consumption from the reference time to the settlement time (step S4). The power management device 20 calculates the difference between the meter display value at the time of settlement and the meter display value at the reference time as the power consumption from the reference time to the settlement time.

The power management device 20 determines whether the power consumption is equal to or less than the first power consumption (step S5). The power management device 20 proceeds to the procedure of step S7 when the power consumption is not equal to or less than the first power amount (step S5: NO).

The power management device 20 calculates the magnitude of the incentive given to the resident when the power consumption is equal to or less than the first power amount (step S5: YES) (step S6). The power management device 20 may calculate the magnitude of the incentive based on the difference between the first power amount and the power consumption amount. The power management device 20 may calculate the magnitude of the incentive based on the value obtained by multiplying the difference between the first power amount and the power consumption amount by the first coefficient. The power management device 20 proceeds to the procedure of step S9 after executing the procedure of step S6.

The power management device 20 determines whether the power consumption amount is larger than the second power amount (step S7). When the power consumption amount is not larger than the second power amount (step S7: NO), the power management device 20 proceeds to the procedure of step S10.

When the power consumption amount is larger than the second power amount (step S7: YES), the power management device 20 calculates the magnitude of the penalty imposed on the resident (step S8). The power management device 20 may calculate the magnitude of the penalty based on the difference between the power consumption amount and the second power amount. The power management device 20 may calculate the magnitude of the penalty based on the value obtained by multiplying the difference between the power consumption amount and the second power amount by the second coefficient.

The power management device 20 makes a payment based on the size of the incentive calculated in the procedure of step S6 or the size of the penalty calculated in the procedure of step S8 (step S9). The power management device 20 may settle the deposit by calculating the refund amount of the security deposit that reflects the magnitude of the incentive or penalty. The power management device 20 may settle the payment by calculating a renewal fee that reflects the magnitude of the incentive or penalty. The electric power management device 20 may settle the payment by transferring an amount corresponding to the size of the incentive to the resident's bank account, credit account, or the like. The power management device 20 may settle the amount by deducting an amount corresponding to the size of the penalty from the resident's bank account, credit account, or the like. The power management device 20 may settle the payment by directly giving points corresponding to the size of the incentive to the point service to which the resident subscribes. The power management device 20 may settle by directly withdrawing points corresponding to the size of the penalty from the point service to which the resident subscribes. The power management device 20 may settle the payment by directly applying electronic money corresponding to the size of the incentive to the electronic money system to which the resident subscribes. The power management device 20 may settle the payment by directly withdrawing the electronic money corresponding to the size of the penalty from the electronic money system to which the resident subscribes. The power management device 20 may notify the management entity of the housing complex of the magnitude of the incentive or the penalty. In this case, the management entity of the housing complex gives the resident an incentive based on the calculation result of the power management device 20 or imposes a penalty.

The power management device 20 determines whether the resident will move out of the dwelling unit (step S10). When the resident moves out of the dwelling unit (step S10: YES), the power management device 20 ends the procedure of the flowchart of FIG. When the resident does not move out of the dwelling unit (step S10: NO), the power management device 20 returns to the procedure of step S1.

The power management device 20 may calculate the magnitude of the incentive or the penalty by executing the steps from step S4 to step S8 at a predetermined timing. The power management device 20 may settle the payment by adding up the magnitudes of the incentives or penalties calculated up to that point in the procedure of step S9.

As described above, the power management device 20 and the power management system 100, the power management method, and the power management program according to the embodiment are incentives or incentives based on the power consumption of each dwelling unit load 42 of the housing complex. Generate a penalty. Due to the occurrence of incentives or penalties, resident behavior can change to reduce power consumption. As a result, the benefits of batch power reception can increase.

The power management device 20 indicates that the resident of the dwelling unit in which the first dwelling unit load is provided receives an incentive because the power consumption of the first dwelling unit load becomes equal to or less than the first power amount, and the residence of another dwelling unit. May be notified. By doing so, the resident can be aware of reducing the power consumption in order to receive an incentive even if he / she is not aware of the reduction of the power consumption. As a result, resident behavior can change to reduce power consumption.
