Research on Allocation Method of Decommissioned Battery Energy Storage Capacity Based on Maximum Annual Net Income

为了退役电池储能系统在园区微网削峰填谷应用中获得更大的经济效益,提出了一种以年净收益最大为目标的容量配置方法。首先,在对退役电池系统经济效益与成本分析的基础上,建立退役电池容量配置模型;其次,采用粒子群算法求解模型;最后,选取某园区微网数据进行仿真分析。结果表明,容量配置方法既提高退役电池储能系统的经济性,又改善负荷的削峰填谷率。研究成果为园区微网配置退役电池储能提供参考。

In order to obtain greater economic benefits from the decommissioned battery energy storage system in the application of peak shaving and valley flling in the park microgrid,a capacity allocation method with the goal of maximizing the annual net income was proposed.Firstly,based on the economic benefit and cost analysis of the decommissioned battery system,a capacity configuration model of the decommissioned battery was established;secondly,the particle swarm algorithm was used to solve the model;finally,the microgrid data of a park were selected for simulation analysis.The results show that the capacity allocation method can not only improve the economy of the decommissioned battery energy storage system,but also update the peak shaving and valley flling rate of the load.This research result can provide a reference for the deployment of decommissioned battery energy storage in the park microgrid.
