Abstract:
1. A method 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 devices and an energy storage equipment group composed of a plurality of energy storage devices capable of both energy generation and storage, the method comprising the steps of: forecasting energy demand for the energy system overall in each time period included in a prescribed term; finding an operation schedule of the energy generation devices 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 devices; changing loads to be allocated to each of the energy generation devices, by a given discrete quantity, either for a plurality of loads simultaneously or separately, and calculating the change in energy supply cost from this change of the loads; and, determining an operation schedule of the energy storage devices, based on the forecasted energy demand and the operation schedule, such that the sum of the energy supply costs of the energy generation devices during the term is minimized, wherein the step of determining the operation schedule of the energy storage devices occurs under the conditions that values are found within a mesh defined by a range of discrete quantities in the change of energy quantity stored by each of the energy storage devices such that the sum of the energy supply costs of the energy generation devices during the prescribed term is minimized.
