基于使用寿命模型的大容量电池储能系统变步长优化控制方法
Variable Step-Size Control Method of Large Capacity Battery Energy Storage System Based on the Life Model
摘要
Abstract
Battery energy storage system (BESS) can improve the schedule ability of wind power. In order to study the control method of BESS life extension, a multifactor life model is developed considering series/parallel and charge/discharge characteristics of BESS. This proposed model can represent the effects on BESS aging, such as charge/discharge rate, control step-size, charge/discharge time and temperature. A variable step-size control method is proposed, after discussing the effects of the control step-size and the dispatch period on BESS life and the fluctuation index. A fuzzy variable step-size controller is designed to adjust the step-size according to charge/discharge rate and fluctuation index. Results indicate that the proposed control strategy combines the longer life feature under large step-size with less volatile feature under small step-size, which enables the power injected to the grid to track the dispatch orders well and the wind farm to be schedulable. Meanwhile, the proposed strategy can improve the life of BESS.关键词
