Analysis and Simulation of Energy Storage System under Micro-island Operation
摘要
Abstract
In order to maintain the stable operation of micro-island system and avoid the greater negative impact of frequent charge and discharge on the performance of traditional battery energy storage system (BESS),this paper introduces a new energy management method of hybrid battery super-capacitor storage system.When the load changes,the super-capacitor responses to the power demand quickly and controls the bus voltage of DC side at the same time.When the DC-side bus voltage is stable,the super-capacitor no longer outputs power and the payload power shortfall is compensated by the battery.This method prevents the battery from being destroyed by the sudden changes of the net-load demand power,optimizes the working process of the battery,and extends the battery lifetime.Finally,a PSCAD model is used to verify the validity of this method.关键词
