摘要:AbstractTaking the photovoltaic power generation with battery energy storage system (BESS) as research object, a charge-discharge control strategy considering charge-discharge depth and state of charge (SOC) of battery is proposed based on the low-pass filter principle. Simulation results show that the proposed control strategy not only can smooth the photovoltaic power fluctuations in real time, but also prolong the service life of the battery.
