摘 要： 如何削弱沖擊負荷對微電網(wǎng)的沖擊是微電網(wǎng)發(fā)展中亟待解決的問題。通過對沖擊負荷特性的分析，選用超級電容器作為儲能裝置，利用儲能來平抑功率的沖擊，并提出了基于頻譜分析的儲能容量配置優(yōu)化方法。由算例分析可以看出，該方法可以兼顧電網(wǎng)的供電可靠性和儲能成本的經(jīng)濟性。

Abstract: How to minimize the impact caused by impact load on microgrid is of significant importance. By analyzing the characteristics of impact load, super capacitors were chosen as the energy storage apparatus to stabilize the power. This paper presented an optimized method to determine the capacity of an energy storage system (ESS), which is based on the spectrum analysis of the load. Calculation examples show that this method could not only stabilize the microgrid but also save the expense of ESS.
Key words: microgrid; impact load; energy storage system; spectrum analysis; super capacitor
