基于 SOC 状态反馈的混合储能功率优化策略
Research on optimal power allocation strategy based on SOC state feedback in hybrid energy storage system
摘要
Abstract
Energy storage system has an important significance for reliable and stable operation of micro-grids.Con-sidering the lack of single form of energy storage, ultra-capacitor-battery hybrid energy storage system is used in this paper.Strategies of power distribution of energy storage system are based on first order inertial filter system, and the method to determine the filter coefficients are introduced.Firstly, a method based on spectrum analysis is proposed to distribute the fluctuated power between the battery and ultra-capacitor.Next, a power distribution strategy of hybrid energy storage system based on SOC feedback is proposed.And fuzzy control method is adopted to adjust system pa-rameters in real time according to the state of charge of the storage system, thus achieving the long term operation of hybrid energy storage system.Finally, the models are built in PSCAD /EMTDC to verify the effectiveness of the pow-er distribution strategies through simulation according to the designed projects.关键词
