摘要
适应风力、光伏等新能源的发展,大容量电池储能系统研发十分必要,而能量转换系统PCS是电池储能系统的一个重要组成部分。为此介绍了两种主要的PCS拓扑结构,并对研究争议较大的DC/DC环节的结构、特点进行了比较分析,结论为:含DC/DC、DC/AC环节的PCS装置的电池储能系统适合于配合新能源的接入;隔离型或非隔离型DC/DC变流器各有优缺点,可视具体情况加以选择;各种复合型DC/DC的拓扑结构的特性及应用研究是大容量PCS装置研发的重要方向。
The power convertion system（PCS） is an important part of the battery energy storage system（BESS） in large scale,which is in need of development to meet the situation of new energy sources such as wind and photovoltaic power developing.This paper analyzes the two main topologies of PCS and compares the constructures and performances of contentious DC/DC links,resulting in conclusion that the BESS with PCS of both DC/DC and DC/AC links is suitable to the access of new energy sources;either isolated or non-isolated DC/DC converter can be chosen depending on the practical situation as each type of converter has its advantages and disadvantages;and further research of large capacity PCS will certainly be implemented on the performance and application of various compound DC/DC converters.
