用于电力平衡的蓄电池储能电站的设计

Design of battery storage power station for power balance

利用蓄电池储能电站调整负荷来保持电力平衡,是解决电力供需矛盾的一种有效途径。建立蓄电池储能电站,蓄电池的选型很重要,因为电池是电站的核心元件。根据机组调峰容量比的概念,建立了调荷容量的数学模型,再结合蓄电池组的调荷容量比,以满足电网综合调荷容量比最小为目标,计算出蓄电池组容量。储能电站的设计中,往往忽略蓄电池连接方式的选择问题,通过多种蓄电池组并串联方案的比较,找出最佳的蓄电池组连接方式,完成锂离子蓄电池储能电站的宏观设计。

It is an effective measure to use battery storage power station to regulate load and keep power balance.For setting up battery storage station,the type selection of batteries which are heart components of the power station is important.The mathematical model of load regulation capacity was built according to the ratio of peak regulation capacity.Then,combined with load regulation capacity ratio of batteries,the capacity of batteries was computed to minimize the integrate load regulation capacity ratio of electricity grid.In design of storage power station,the choice of connection mode is often neglected.Through comparing several schemes of serial-parallel batteries,the best scheme was found to finish the whole design of lithium-ion battery storage power station.
