Host and charging and discharging scheduling method for energy storage apparatus

Abstract

a host and a charging and discharging scheduling method for an energy storage apparatus are provided herein. The host includes a storage circuit and a processor. The storage circuit is configured to store program code. The processor is coupled to the storage circuit and is configured to access the program code to perform the following operations. Obtain electricity supply and demand data. Predict a frequency trend of a power grid based on electricity supply and demand data. Based on the frequency trend and a power company dispatch instruction, a charging and discharging scheduling strategy for an energy storage apparatus is generated. Furthermore, the charge and discharge scheduling strategy includes a plurality of charge and discharge curves of the energy storage apparatus and a plurality of state of charge (SOC) interval parameters corresponding to the plurality of charge and discharge curves. Execute a scheduled loop. Furthermore, the scheduling loop is configured to calculate the output power value of the energy storage device based on a real-time SOC of the energy storage device, a real-time frequency of the power grid, the power company dispatching instruction of, and the charging and discharging scheduling strategy. Furthermore, the energy storage device outputs the output power value to the grid. Repeat the scheduling cycle until the specified schedule ends.
