Abstract

Abstract: To improve the controllability of the power generation of renewable energy such as photovoltaic power, wind power, etc., and avoid the negative impact of power fluctuation caused by external environmental changes on power grid, this paper proposes a hybrid energy storage system based on two-stage energy storage converter, which adopts PQ control strategy to suppress renewable power fluctuation. The energy compensation for energy storage system is estimated by low pass filter algorithm, then the controller is further designed to accurately control the power flow of energy storage and achieve timely and accurate energy exchange between energy storage system and power grids. Finally, this paper constructs a model for hybrid energy storage system under the background of photovoltaic power generation in MATLAB/SIMULINK platform. The simulation results show that, this method can smooth the output power of the photovoltaic power generation module smooth and has the suppression effect, which can meet the requirements of real-time scheduling of power system.

Key words: energy storage converter, hybrid energy storage system, control strategy, power suppression
