Abstract：When the penetration of photovoltaic system is high in a distribution network, energy storage system is available to reduce the impact on grid caused by PV power fluctuation.In order to smooth PV power,this paper proposes a control method of energy storage system based on the short-time photovoltaic power prediction technology and low-pass filtering principle.By using this method,the delay caused by traditional low pass filter method is eliminated and the influence of photovoltaic power prediction error on control effect is also reduced.As a result,the control effect is improved and the capacity of energy storage system is limited.The simulation results show that the strategy can effectively reduce the fluctuations of PV power,and prevent storage system to be over-charged or over-discharged.
