An EMS includes a target presentation unit indicating target power, a power acquisition unit that obtains combined power obtained by adding power output from the photovoltaic power generation system, power consumed by the power consumer, power output from the power generation system, power consumed by the hydrogen production system, and power output or consumed by the storage battery system, and a command value generation unit that generates a command value such that the combined power asymptotically approaches the target power. The combined power includes a long- and intermediate-period component and a short-period component. The command value generation unit outputs a command value corresponding to the long- and intermediate-period component to the power generation system or the hydrogen production system. The command value generation unit outputs a command value corresponding to the short-period component to the storage battery system.

Power system adjusting device and power system adjusting program

There is provided a power adjustment method in a microgrid connected to an external power supply system and having a power storage unit capable of adjusting an amount of stored power by charging and discharging and a power consumption unit capable of adjusting power consumption of the power. The power adjustment method includes adjusting transmission and reception of the power by simultaneously controlling the power consumption in the power consumption unit and charge/discharge power in the power storage unit in order to transmit and receive power based on a planned value determined for each planned section to and from the external power supply system.

Power regulation method and power regulation device

A demand and supply planning method generates a supply-demand plan including information that specifies operation of an energy generation unit for each unit time in a microgrid having energy generation units being connected to an external energy supply system and generating energy while consuming fuel, an energy storage unit, and a load unit; by calculating an optimization problem related to an objective function including terms related to energy transfer from the external energy supply system in the microgrid and terms related to fuel consumption in the microgrid by using a constraint condition related to a relationship between information related to an operating duration time in each of the one or more energy generation units at a start time for generating the supply-demand plan and a minimum operation time constraint of the energy generation unit; and outputting the supply-demand plan based on a calculation result of the optimization problem.
