摘要

针对储能系统不规则充放电导致的电池组一致性变差及单体电池过充/过放问题，研究铅炭电池组一致性变化规律，提出考虑电池组一致性的储能系统功率控制策略。采用包含储能电池组、风/光发电、电动汽车和常规负荷的共直流母线型集中式微电网并网示范平台的实测数据对所提功率控制策略与传统控制策略进行对比仿真分析。仿真结果表明，所提控制策略可有效降低电池组荷电状态（SOC）变化范围，提升电池健康状态，提高电池组一致性，减少过放电池数量，增强储能系统双向调节能力。

Abstract

In order to solve the problem of battery consistency variation and overcharge/overdischarge caused by irregular charging and discharging of energy storage system

the consistency of lead carbon battery pack is studied and the power control strategy of energy storage system considering battery consistency is proposed. The proposed power control strategy is compared with the traditional strategy by using the actual operation data of grid-connected demonstration platform of centralized microgrid with common DC bus. The platform includes energy storage battery pack

wind/photovoltaic power generation

electric vehicles and conventional loads. The simulation results show that the proposed control strategy can effectively reduce the state of charge (SOC) range of battery pack

improve battery health and battery pack consistency

reduce the number of overdischarged batteries and enhance the bidirectional adjustment capability of energy storage system.
