Research on Capacity Configuration of Energy Storage System for PCC of Micro-grid Power Output Smoothness

针对微电网并网点出力波动的特点,提出了一种基于一阶低通滤波算法的储能系统容量配置方法。该方法首先通过对滤波时间常数寻优,继而利用储能系统充/放电功率累加计算电池的最大容量。最后仿真分析利用微电网运行历史数据进行储能配置容量的计算,结果验证了研究的可行性和有效性。

For the fluctuation of the micro-grid PCC output, this paper proposed an energy storage systemcapacity configuration method based on first order low pass filter algorithm. The process is to find the best filter timeconstant and get the largest capacity of battery through the energy storage system charge-discharge poweraccumulation. The last simulation uses historical data of actual wind farm to calculate battery capacity of energystorage system. The result shows the feasibility and effectiveness of the research.
