Research on Unit Regulation Strategy Based on the Remaining Power of Energy Storage Battery

This paper mainly studies the unit adjustment strategy based on the remaining energy of the energy storage battery, and timely adjusts the unit side control according to the SOC state of the remaining energy storage battery, and does not purely rely on the action of the energy storage side, so that the SOC of the battery remaining energy is always maintained at the middle value. It takes full advantages of battery energy storage frequency modulation response speed to act as much as possible for each secondary frequency-modulation AGC (automatic generation control) and primary frequency modulation. It can reduce battery loss and extend battery life. It can actively respond to each AGC and one FM action command, bringing considerable economic benefits to the power plant.
