面向冲击负荷的微电网储能容量优化配置研究

摘要

如何削弱冲击负荷对微电网的冲击是微电网发展中亟待解决的问题。通过对冲击负荷特性的分析，选用超级电容器作为储能装置，利用储能来平抑功率的冲击，并提出了基于频谱分析的储能容量配置优化方法。由算例分析可以看出，该方法可以兼顾电网的供电可靠性和储能成本的经济性。%How to minimize the impact caused by impact load on microgrid is of significant importance. By analyzing the char-acteristics 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.
