Abstract

Using battery energy storage system (BESS) to smooth wind power volatility can improve the stability of wind power output. According to the intermittence and volatility of wind power output, a smoothing control strategy by using moving average algorithm for wind power was proposed, which took the state of charge (SOC) in energy storage system and wind power volatility rates into account. It was compared with the traditional first-order low-pass method for smoothing wind power output. The effectiveness of the proposed control strategy was verified with the MATLAB/SIMULINK simulation, whose results have shown that it can smooth the wind power output, and can effectively decrease the battery energy usage and storage energy.
