摘　　要：以研究储能系统出力为目标,从时间、频率角度研究光伏发电波动性,以EMD算法对光伏发电频率进行分解,通过分解得出的IMF残值得出:在多云天气下,光伏发电系统内储能出力频繁,平抑光伏波动强,晴朗天气下,储能系统的出力具有规律性且时间固定的结论。With the output of energy storage systems as the research objective,this paper studies the volatility of photovoltaic power generation from the perspective of time and frequency.The frequency of photovoltaic power generation is decomposed by the EMD algorithm.Through studying the residual value of the IMF obtained by decomposition,the following conclusion is found:in cloudy weather,the energy storage output within the photovoltaic power generation system is frequent with strong capability of stabilizing the photovoltaic power fluctuations;in sunny weather,the output of the energy storage system is regular and time fixed.
