摘要
储能变流器(Power Conversion System,PCS)是实现储能电池与电网功率交换的重要单元,其作为连接电池与负荷之间的电能转换装置,可以对充电、放电过程实现控制,并进行交直流的转换。其性能的好坏关系到能量传输质量,合理的储能逆变器设计对于促进能源消纳有重要的意义。对基础的单双级电路做简要介绍,针对双级式中的DC/DC变换器做合理分析,并总结出改进型方案,提出当前主要的研究难点,对研究前景进行展望,为今后发展提供便捷且可靠的参考。
Power conversion system(PCS) is an important unit to realize the power exchange between energy storage batteries and power grid. As an energy conversion device connecting batteries and loads, PCS can control the charging and discharge process and convert AC and DC. Its performance is related to the quality of energy transmission. Reasonable design of energy storage inverter is of great significance to promote energy consumption.This paper gives a brief introduction to the basic single and double stage circuit, makes a reasonable analysis of the bipolar DC/DC converter, summarizes the improved scheme, puts forward the main research difficulties at present,prospects the research prospect, and provides a convenient and reliable reference for future development.
