摘　　要：引入光伏功率预测误差,分析其概率统计规律,并利用置信区间去估计储能最大发出(吸收)功率的方法,使储能系统既能满足一定置信水平下的功率波动补偿,又优化了容量配置。采用本文提出的方法配置储能系统,然后利用Matlab/Simulink仿真软件建立了相应的光储联合系统模型,并采用实际气象数据驱动模型来进行并网控制的仿真研究,验证了提出方法的可行性。This paper introduces PV power forecasting errors, analyses its probability and statistics law, and then applies confidence interval to estimate the maximum giving - out （absording） power of ES, which makes ES meet power compensation In a certain con- fidence level and optimizes capacity collocation of ES at the same time. At last, method proposed in this paper is applied to collocate ES capacity, and then corresponding PV/ES hybrid system is built by applying Matlab/Simulink, and applies actual weather data to drive the model built to simulate grid -connected control, which tests and veriffies the method proposed in this paper effective and practicable.
