Method and device for operation scheduling for energy storage equipment

A device for operation scheduling for energy storage equipment in an energy system which has an energy generation equipment group composed of a plurality of energy generation equipments and an energy storage equipment group composed of a plurality of energy storage equipments capable of both energy generation and storage, the device comprising:

• an energy demand forecast part which forecasts energy demand for the energy system overall in each time period included in a prescribed term;
• an energy generation equipment operation scheduling part which finds an operation schedule of the energy generation equipments such that an operation schedule for each time period is found which satisfy energy demand for a prescribed term in each of the energy generation equipments;
• a part which changes the loads to be allocated to each of the energy generation equipments, by a given discrete quantity, either for a plurality of loads simultaneously or separately, and calculates the change in energy supply cost from this change of the loads;
• and,
• an energy storage equipment operation scheduling part which determines an operation schedule of the energy storage equipments, based on the forecasted energy demand and the found operation schedule, such that the sum of the energy supply costs of the energy generation equipments during the term is minimized.
