基于多因素的储能系统剩余电量估计方法
Estimation Method for Residual Capacity of Energy Storage System Based on Multi-factor
摘要
Abstract
Battery capacity is the critical operational parameter of the energy storage system which can decide whether the system runs normally or not. In order to accurately estimate battery capacity and reduce estimation errors and fluctuation amplitudes,this paper presents a kind of multi-factor staged capacity estimation method considering electromotive force,re-sistance and terminal voltage weighted combination with ampere-hour correction on the basis of traditional battery capacity estimation methods.By making experiments with the traditional capacity estimation method,the electromotive force,resist-ance and terminal voltage weighted combination method and the proposed new method on the energy storage system com-posed of lead-acid battery,inverter charge and discharge machine,comparing and analyzing the experimental results,it dis-covers the maximum absolute error value of capacity estimation obtained by the new method is 2.23% and the standard devi-ation of error fluctuation amplitudes is 0.838 5,which indicates that the proposed method can realize precise estimation on the lead-acid battery capacity of the energy storage system and verifies effectiveness of this new method.关键词
