- the business hours of the stores 300A, 300B, and 300C, the number of storage batteries 340B and 340C, and the number of quick chargers 350A, 350B, and 350C are as shown in Table 1 below.
- Example 1 Change target power consumption
- Table 2 shows DR that promotes the consumption of surplus power for charging service providers.
- the table shows an example in which surplus power is generated from 22:00 to 1 o'clock in the night when there is little power use, and rebates are given as much as the surplus power is consumed.
- a DR For such a DR, conventionally, for example, 5 kW is allocated to all stores without considering information for each store.
- the target time for DR is 3 hours, but store 300A is not open during the target time, and store 300B is open for only 1 hour of the target time, so the total usage is 4 hours.
- the amount of power is 20 kWh.
- the operation management server 210 determines a power usage target value for each store according to the information of each store.
- the operation management server 210 may be set with a function for determining a power use target value for each store.
- the function can appropriately include parameters from the number of quick chargers, the power consumption of the quick charger, the capacity of the stationary storage battery, the business hours of the store, the number of EV visits per day, etc. for each store.
- the function can also include an experience value related to the relationship between the unit price at the charging service provider or the store and the number of customers. These parameters can be acquired from the store information management server 220.
- the operation management server 210 replaces the DR from the CEMS server 110 with a commit-type DR in which a power usage target value is set for each store, for example, as shown in FIG. Send to store.
- the allocation of power consumption during business hours is initially 5 kW for each store. Since the store 300A is closed at 21:00, the stores 300B and 300C that are in operation are engaged and assigned the same power consumption after 21:00. Since it becomes the DR target time at 22:00, the operation management server 210 will equally apply 2.5 kW to the stores 300B and 300C that are in operation for the amount of power used allocated to the store 300A that is closed. Let Therefore, the allocation of the power usage amount of the stores 300B and 300C after 22:00 is 7.5 kW.
- the operation management server 210 causes the store 300C to bear the portion of the store 300B allocated after 23:00.
- the allocation of the power usage amount of the store 300C is 15 kW from 13:00 to 1 o'clock of the next day when the DR target time ends, and the total power usage amount in all stores 300A to 300C in the DR target time zone Is 45 kW.
- the EV user is notified of information useful for the EV user who uses the quick charger, and the time period in which the consumption promotion of surplus power is trained ( By inviting users to visit the store from 22:00 to 1 o'clock, the company aims to promote the consumption of surplus power during the time period (22:00 to 1 o'clock).
- the information useful for the EV user may depend on a billing form for the charging action of the EV user. For example, when the charging structure for the charging action of the EV user is a one-time charging charging form, the privilege information useful for the EV user can be a charging fee discount per charging.
- the privilege information useful for the EV user can be a charge charge discount per electric energy.
- the charging method for the charging action of the EV user is a one-time charging charging method
- the privilege information useful for the EV user can be a charging time extension per charging fee.
- the billing form for the EV user's charging action is a monthly fixed amount form
- privilege information useful for the EV user can be given points. In addition to the charge charge discount, for example, points may be given according to the amount of charge, charging time may be shortened, gifts of crude products, or additional services such as car washing may be used.
- the operation management server 210 operates the portion of the power used by the store that does not affect the target time zone of the DR according to the business hours of each store, using the DR presented from the CEMS server 110. It can be replaced with a commit-type DR for each store, which is borne by a certain store.
- the information included in the committed DR replaced for each store includes, for example, the unit price of power to the customer, the amount of power received to the quick charger, It may be the amount of power received by the storage battery, the place where the transportable stationary storage battery is installed, the business hours of the store, and the like.
- the specification of the power supply / demand adjustment instruction presented by the external organization is not limited to the above example.
- incentives for promoting power consumption when surplus power is generated are shown in the peak time rebate rate system, but for example, time-based charges (Time of Use) and emergency peak charges (Critical) It may be a Peak Pricing, a Commitment Rebate (Capacity Commitment Program), a Pay-by-Rebate (Limited Peak Time Rebate), or a duplicate demand response that combines these fee systems.
- Example 2 Changing business hours
- DR sent from the CEMS server 110 is the same as that in Example 1.
- the difference between this example and Example 1 lies in the conversion rule of the power supply / demand adjustment instruction by the information replacement function of the operation management server 210, and the others may be the same unless otherwise specified.
- the operation management server 210 prioritizes the acquisition of rebates according to the information of each store, and sets the business hours of each store so that all stores are open in the target time zone of DR. For example, for the store 300A, the business hours are extended from 21:00 to 1 am on the next day, and for the store 300B, the business hours are extended from 23:00 to 1 am on the next day. Since the store 300C is open 24 hours, the business hours are not changed.
- the power usage target value of each store can be set according to the facilities of each store. For example, in the case of this example, among the three stores 300A to 300C, the store 300C has two quick chargers installed, and the store 300C performs power assist when the charging power to the EV is insufficient.
- the business hours and power usage target values of each store can be set based on the information of each store acquired from the store information management server 220.
- the operation management server 210 replaces the DR from the CEMS server 110 with a commit-type DR whose business hours are changed for each store, and sends the replaced DR to each store.
- the DR from the CEMS server 110 can be replaced with a commit-type DR for each store that reflects the charging service provider's policy.
- the charging service provider selects acquisition of rebates rather than labor costs
- the business hours of the store can be changed according to the policy.
- the power usage target value of the corresponding stores may be set high. It is possible to guide customers appropriately in consideration of the difference in the facility environment of each store, and to perform efficient power supply and demand adjustment.
- Example 3 Change of power usage target value according to storage battery status of each store
- Example 3 Change of power usage target value according to storage battery status of each store
- the other may be the same unless otherwise specified.
- the DR on the day when the peak time rebate as shown in Table 3 is introduced is requested from the CEMS server 110 to the operation management server 210.
- the power demand adjustment for example, in order to encourage the suppression of power consumption in the time zone from 11:00 to 13:00 when the power demand increases in summer, etc. Show.
- the capacity of the storage battery held by the store 300B and the store 300C is 30 kWh and 60 kWh, respectively, and the filling state (State of Charge) is 50% for the storage battery of the store 300B and 80% for the storage battery of the store 300C. .
- the operation management server 210 replaces the DR from the CEMS server 110 with the commit type DR in which the power usage target value of each store is set according to the storage battery status of each store acquired in real time from the store information management server 220.
- the replaced DR is sent to each store.
- a commit-type DR to be sent to each store for example, a store 300A that does not have a storage battery sets a power usage target value lower than other time zones from 11:00 to 13:00, which is a target time zone of DR. Earn rebates.
- the store 300B has one storage battery, but the state of charge is 50%. Therefore, the storage battery is used between 12:00 and 13:00 when the power consumption is expected to increase in the DR target time zone. Suppress.
- the store 300C has one storage battery and has a good state of charge of 80%. Therefore, the store 300C uses the storage battery to suppress power usage during the DR target time zone from 11 to 13:00. Then, power is stored in the storage battery using the power from 13:00 to 17:00 after the DR target time zone in which power usage is expected to decrease.
