- Equation 9 sets the baseline power P WE,plan,i in DR to be equal to or less than the difference between the rated power of the hydrogen production facility 14 and the increased DR possible amount P DR,up,i. It is defined to be a value that can be responded to.
- Formulas 10 and 11 are constraints for calculating the DR possible amount according to the length of the product block in the electricity balancing market (for example, 3 hours). "mod" in Equations 10 and 11 indicates a modulus operation.
- the length of a product block in the power supply and demand adjustment market is the period during which the power demand (power purchase amount) should be adjusted in response to one DR command, and is determined by market requirements.

For example, the operation plan creation unit 52 determines the amount of purchased electricity E grid,i , the possible increase DR amount P DR,up,i , the possible decrease DR amount P DR,down,i , the base Operation plan data including values of the line electric power P WE,plan,i and the electrolysis electric power (in other words, operation amount) P WE,i of the hydrogen production facility 14 of the hydrogen production facility 14 may be created.
- the operation plan output unit 54 transmits data of the operation plan created by the operation plan creation unit 52 to the hydrogen station 12 (gateway device 18).
- the parameter acquisition unit 48 of the management server 40 acquires the values of various parameters necessary for creating an operation plan for the hydrogen production equipment 14 from an external device and stores them in the storage unit 44 .

- the hydrogen station 12 adjusts power consumption when the remaining amount of hydrogen in the hydrogen storage facility 16 can be maintained within the range of the minimum storage amount or more and the maximum storage amount or less. For example, according to the increase DR command, the electrolysis power of the hydrogen production equipment 14 is increased to increase the amount of hydrogen production. Alternatively, according to the lower DR command, the electrolysis power of the hydrogen production equipment 14 is lowered to reduce the amount of hydrogen production. Alternatively, the operation of the hydrogen production facility 14 is stopped according to the lowered DR command.
- an appropriate DR possible amount can be set according to the remaining amount of hydrogen in the hydrogen storage facility 16 and the DR consideration per unit time.
- an appropriate DR possible amount for example, it is possible to suppress the occurrence of a situation in which the DR command cannot be complied with.

- a DR command (increase DR command or decrease DR command) is randomly issued based on a random number within the range of the possible DR amount submitted to the resource aggregator the previous day. It was supposed to be given. However, it was decided that the raising DR command and the lowering DR command should not be issued at the same time.
- an increase DR command is issued such that the remaining amount of hydrogen (V H2,tank,i ) in the hydrogen storage facility 16 exceeds the upper limit (V H2,tank,max )
- the increase DR command is ignored and hydrogen production is stopped. Therefore, the DR fails.
- FIG. 4 shows control simulation results (trial calculation results) of the first embodiment and the comparative example.
- the power purchase cost per unit amount of hydrogen production (1 Nm 3 ) was obtained when the hydrogen production facility 14 was operated according to the operation plan in each of the first embodiment and the comparative example.

- the hydrogen inventory may be below the lower limit when receiving a downward DR command. In this case, hydrogen production (operation of the hydrogen production facility 14) must be performed ignoring the lower DR command, resulting in DR failure. Further, in the comparative example, the hydrogen inventory may exceed the upper limit when receiving the increase DR command. In this case, the increased DR command must be ignored and the hydrogen production (operation of the hydrogen production facility 14) must be stopped, resulting in DR failure as well.

Abstract
Description
まず第1実施例の概要を説明する。第1実施例における「デマンドレスポンス」(以下「DR」とも呼ぶ。)は、電力供給量にあわせて電力需要量を調整することにより電力の需給バランスを調整する仕組みである。DRは、需要制御のパターンとして、上げDRと下げDRを含む。上げDRは、電力需要量を増加させる制御であり、例えば再生可能エネルギーの出力が過剰になった場合等に実施される。言い換えれば、一例として上げDRは、消費電力を増加させることで電力の需給バランスを調整する。下げDRは、電力需要量を減少させる制御であり、例えば電力消費がピークになった場合等に実施される。言い換えれば、一例として下げDRは、消費電力を低下させることで電力の需給バランスを調整する。電力の需要家(企業等)は、DRの指令に応じて消費電力(言い換えれば買電量)を制御することにより、DRの対価(収入または報酬ともいえる)を得ることができる。
