Calculate individual billed charges. The calculation of the individual bill charges by the management device 10 will be described in detail below.

  The first rule is set by, for example, a power company that supplies power via the power network 18. An electric power company that makes a collective power reception contract with the electric power company can, as described above, conclude a contract to collectively receive electric power to the entire complex customer facility 12 with the electric power company. The first rule may be defined by the contract. Furthermore, the first rule may be based on a low-voltage package call agreement. The first rule defines, for example, a basic charge and a charge unit price per consumed electric energy.

  Note that the second rule is set by, for example, a power company who makes a collective power reception contract with the power company. A user of each of the plurality of customer facilities 13 can connect a contract for receiving power to the customer facility 13 to be used with the electric power company. The second rule may be defined by the contract. The second rule may be the same for all users of the plurality of customer premises 13. Alternatively, the second rule may differ depending on the consumption pattern of the user. Alternatively, the second rule may be the same as the charge rule applied when the user concludes a power reception contract with the power company alone.

  Note that the third rule is set by, for example, a power company that receives power via the power network 18. An electric power company that makes a collective power reception contract with the electric power company can form a contract with the electric power company to sell the power generated by the renewable energy generation facility. The third rule may be defined by the contract.

  The management device 10 calculates the overall power rate of the entire complex customer facility 12 based on the received power amount and the first rule. The management device 10 calculates the individual power rates of the plurality of customer facilities 13 and the common facility 15 based on the individual power consumption amounts of the plurality of customer facilities 13 and the common facility 15 and the second rule. The management device 10 calculates the sales price of the power generated by the distributed power supply 14 to the power network 18 based on the amount of supplied power and the third rule. The management device 10 calculates the overall benefit by subtracting the calculated total power rate from the calculated total value of the individual power rates of the all customer facilities 13 and the shared facilities 15 and adding the calculated sales price.

  The management apparatus 10 may add the remuneration determined for the reduction of the power consumption in the complex customer facility 12 based on the demand response request to the overall benefit. In the complex customer facility 12, a demand response may be received from a power company (supplier) that supplies power via the power network 18. The demand response is a power consumption reduction target set for each customer facility 13 for the purpose of peak shift of power demand and the like. The management device 10 acquires, for example, a notification of the reduction of the power consumption due to the demand response request from the power company via the communication network 28, and stores the notification in the built-in memory. When the management apparatus 10 receives the notification indicating that the power consumption has been reduced, the management apparatus 10 adds, to the overall benefit, a reward determined for the demand response request. The compensation for the demand response request may be determined by the power company, for example.

  The management device 10 calculates the individual benefit to the user of each of the electric power company (first beneficiary) and the plurality of customer facilities 13 who conclude a collective reception agreement with the electric power company by distributing the entire benefit. . The management device 10 may calculate an individual benefit to the second beneficiary to be distributed from the overall benefit. In the present embodiment, the management device 10 calculates an individual benefit to the second beneficiary. The second beneficiary is, for example, the owner of the complex consumer facility 12 when the owner of the distributed power supply 14 is different from the owner of the complex consumer facility 12. In the present embodiment, the individual beneficiary of the second beneficiary may be the fee for using the complex consumer facility 12 for installing the distributed power supply 14.

  The management apparatus 10 distributes the entire benefit to the individual benefit of the electric power company, the individual benefit of the second beneficiary, and the individual benefit of all the consumer facilities 13 according to various methods including the method exemplified below. Do. The individual benefit of all customer facilities 13 is the sum of the individual benefits to the users of all customer facilities 13. Furthermore, the individual benefits of all the customer facilities 13 may include the individual benefits for the owner of the shared facility 15.

  For example, the individual benefit of the electric utility may be based on which of a plurality of price ranges in which the individual benefit of the electric utility is defined includes the overall benefit. Also, the individual benefit of the power company may be set to a fixed amount. Furthermore, the individual benefit of the utility may be zero. Also, the individual beneficiaries of the electric power company may be the total beneficiaries minus the individual beneficiaries of the second beneficiary and the individual beneficiaries of all the customer facilities 13. In addition, the individual beneficiaries of the electric power company may be values obtained by multiplying the whole beneficiaries by a factor of 1 or less. The factor may be constant. Alternatively, the coefficient may decrease as the power consumption rate of the entire complex customer facility 12 increases. In the case of changing the coefficient, an upper limit and a lower limit may be provided.

  The power consumption rate of the complex consumer facility 12 as a whole is the ratio of the electric energy consumed by using the electric power generated by the distributed power supply 14 to the energy consumed by the complex consumer facility 12 as a whole. The amount of power consumed by the entire complex customer facility 12 is the sum of the individual amounts of power consumption detected by the plurality of second power meters 24 respectively. The amount of power consumed by the entire complex customer facility 12 of the power generated by the distributed power source 14 is the individual power consumption detected by each of the plurality of second power meters 24 when power is supplied to the power network 18 It is the sum of the quantity itself. Further, the amount of power consumed by the entire complex customer facility 12 of the power generated by the distributed power supply 14 is individually detected by each of the plurality of second power meters 24 when power is received from the power network 18. It is a value obtained by subtracting the received power amount from the power consumption amount, or the generated power amount detected by the third power amount meter 17. The management apparatus 10 detects whether the first power meter 23 detects the amount of received power or whether the amount of supplied power is received, whether the power is received from the power network 18 or the power is supplied to the power network 18. Based on the presence of

  The management device 10 may calculate the power consumption rate for each unit time of detection of the first watt-hour meter 23 and the second watt-hour meter 24.

  When the unit time of calculation of the power consumption rate is shorter than the target time of calculation of the electricity rate, the management device 10 stores the calculated power consumption rate in the built-in memory, and calculates all over the target time of calculation of the electricity rate. The coefficient may be calculated using a value obtained by averaging the power consumption rate.

  Alternatively, the management device 10 calculates the amount of power consumed by the entire complex consumer facility 12 of the power generated by the distributed power supply 14 every unit time of detection of the first watt-hour meter 23 and the second watt-hour meter 24. You may Furthermore, the management device 10 may calculate the amount of consumed power by using the power generated by the distributed power supply 14 in the target time of the calculation of the electricity charge by accumulating the calculated amount of power. Furthermore, the management device 10 consumes the amount of power consumed using the power generated by the distributed power source 14 at the target time for calculating the electricity rate, and the power consumed by the entire combined customer facility 12 at the target time for calculating the electricity rate. The power consumption rate may be calculated based on the amount, and the factor may be calculated based on the power consumption rate.

  Also, for example, the individual benefit of the second beneficiary may be set to a fixed amount. Also, the individual beneficiaries of the second beneficiary may be zero. Furthermore, the individual beneficiary of the second beneficiary may be a value obtained by loading a value obtained by multiplying the whole beneficiary by a factor of 1 or less on the fixed amount.

  Also, for example, the individual benefits of all customer facilities 13 may be based on which of a plurality of price ranges in which the individual benefits of all customer facilities 13 are defined includes the entire benefits. Moreover, the individual benefit of all the consumer facilities 13 may be set to a fixed amount. In addition, the individual beneficiaries of all the consumer facilities 13 may be the total beneficiaries minus the individual beneficiaries of the electric power company and the second beneficiaries. Further, the individual benefit of all the customer facilities 13 may be a value obtained by multiplying the entire benefit by a factor of 1 or less. The factor may be constant. Alternatively, the coefficient may increase as the power consumption rate of the entire complex customer facility 12 increases. In the case of changing the coefficient, an upper limit and a lower limit may be provided.

  When the management device 10 calculates the individual benefits of all the customer facilities 13, the management device 10 distributes the individual benefits of all the customer facilities 13 to calculate the individual benefits for the users of each of the plurality of customer facilities 13. The management apparatus 10 distributes the individual benefits of all the customer facilities 13 to the individual benefits for the users of each of the plurality of customer facilities 13 according to various methods including the method exemplified below.

  For example, the individual benefits of the users of each of the plurality of customer facilities 13 may be calculated by dividing the individual benefits of all customer facilities 13 by the number of all customer facilities 13. In the case of giving individual beneficiaries to the owner of the shared facility 15, the individual beneficiaries of the users of the plurality of customer facilities 13 and the owners of the shared facility 15 are the individual beneficiaries of all the customer facilities 13, It may be calculated by dividing by the number of all customer facilities 13 and shared facilities 15. Further, the individual benefit of the user of each of the plurality of customer facilities 13 may be calculated according to the floor area of each customer facility 13. Further, the individual benefit of the user of each of the plurality of customer facilities 13 may be calculated according to the power consumption rate in each customer facility 13. For example, the individual benefits of the users of each of the plurality of customer facilities 13 may be distributed to be higher as the power consumption rate is higher. Furthermore, the individual benefit of the user of each of the plurality of customer facilities 13 may be a value obtained by multiplying each individual power rate by a first coefficient (for example, 5%) equal to or less than one. However, if the sum of the individual beneficiaries of the users of each of the plurality of customer facilities 13 is larger than the total beneficiary, a value multiplied by a second coefficient (for example, 3%) smaller than the first coefficient is multiplied again You may calculate it.

  The power consumption rate in the customer facility 13 is the ratio of the amount of power consumed using the power generated by the distributed power supply 14 to the amount of power consumed in the customer facility 13. The amount of power consumed by the customer facility 13 is an individual amount of power consumption detected by the second power meter 24. The amount of power consumed by the customer facility 13 of the power generated by the distributed power source 14 is the individual power consumption itself detected by the second power meter 24 when power is supplied to the power network 18. On the other hand, the amount of power consumed by the customer facility 13 of the power generated by the distributed power supply 14 is calculated by the following equation (1) when power is received from the power network 18.

In equation (1), sconW _k is the amount of power consumed by each customer facility 13 of the power generated by the distributed power supply 14. Further, wconW _k is the amount of power consumed by each customer facility 13, that is, the amount of power detected by the second power meter 24 corresponding to the customer facility 13. n is the number of customer facilities 13 possessed by the complex customer facility 12. When the complex customer facility 12 calculates the individual benefit of the shared facility 15, n is the total of the number of customer facilities 13 and the shared facility 15 possessed by the complex customer facility 12. genW is the amount of power generated by the distributed power supply 14 and supplied to the main stem 21, that is, the amount of generated power detected by the third power meter 17.

  In addition, instead of the electric energy which the third power meter 17 detects, the management device 10 detects the amount of electric power generated by the distributed power source 14 of the individual power consumptions detected by the plurality of second electric power meters 24 respectively. It may be calculated by subtracting the amount of received power detected by the first power meter 23 from the sum. According to such a configuration, even if the third power meter 17 is not provided, the amount of power generated by the distributed power supply 14 can be recognized.

  The management device 10 may calculate the power consumption rate of the customer facility 13 every unit time of detection of the first watt-hour meter 23 and the second watt-hour meter 24.

  When the unit time of calculation of the power consumption rate is shorter than the target time of calculation of the electricity rate, the management device 10 stores the calculated power consumption rate in the built-in memory, and calculates all over the target time of calculation of the electricity rate. The average value of the power consumption rate may be used to calculate the individual benefit of the user of the customer facility 13.

  Alternatively, the management device 10 calculates the amount of power consumed by each customer facility 13 of the power generated by the distributed power supply 14 every unit time of detection of the first watt-hour meter 23 and the second watt-hour meter 24. You may Furthermore, the management device 10 may calculate the amount of consumed power by using the power generated by the distributed power supply 14 in the target time of the calculation of the electricity charge by accumulating the calculated amount of power. Furthermore, the management device 10 uses the amount of power consumed using the power generated by the distributed power source 14 at the target time for calculating the electricity rate and the amount of power consumed at the customer facility 13 at the target time for calculating the electricity rate. Based on the power consumption rate, the power consumption rate may be used to calculate the individual benefit of the user of the customer facility 13.

  When the management device 10 calculates the individual benefit of the user of the customer facility 13, the individual billing fee is calculated by subtracting the individual benefit from the individual power charge calculated for the user separately for the customer facility 13. Do. The management device 10 can output the calculated individual charge. The individual bill may be output as an image on a display. Also, the individual billing fee may be output as a printed matter using a printer. In addition, the individual charge may be output as data to a settlement company such as a bank.

  The management device 10 may output at least one of the power consumption rate of each of the plurality of customer facilities 13 and the amount of power consumed by the distributed power source 14. For example, at least one of the power consumption rate and the power amount may be output as an image on a display. In addition, at least one of the power consumption rate and the power amount may be output as a printed matter using a printer. For example, at least one of the power consumption rate and the power amount may be printed on a bill for the user of the customer facility 13 or the like and presented to the user. Furthermore, the management device 10 may convert the amount of power into an index indicating the CO 2 reduction effect and the use reduction effect of petroleum, and may output it.
