Study on frequency modulation control strategy of electrochemical stored energy considering the state of battery charge

Abstract

Firstly, the overall modeling process of stored energy is described. Secondly, in order to better simulate the change of power frequency response characteristics of stored energy with state of charge (SOC), an adaptive control strategy is proposed to improve the frequency modulation response characteristics of stored energy in a high proportion of new ensergy grid. Finally, the effectiveness of the control strategy is verified in the simulation software, aiming at the operation result of the energy-type stored energy under different charging conditions after the disturbance occurs.
