摘要
随着分布式发电和微电网技术的发展,传统储能变流器已不能满足现在的技术要求。在此提出一种新型拓扑结构,不仅满足传统并网工作模式的要求,而且满足离网工作模式的要求。详细介绍了该拓扑结构的工作原理和并/离网工作模式下的控制方法,在此基础上,研制了一台100 kW并/离网双模式储能变流器。通过光储联合运行实验,结果表明该储能变流器功能强大,动态响应快,充放电电流谐波电流小,具有很好的推广价值。
With distributed generation and miero grid teehnology, the traditional energy storage converter can not meet the technical re quirements.This paper presents a new topology, which can meet the traditional requirements of grid mode, and also the requirements of off-grid mode.The working principle and topology, eonnected/off-grid control mode of operation are described.On this basis, a 100 kW eonnected/off-grid dual-mode energy storage converter is developed.PV and storage joint operation is tested, the results show that the energy storage eonverter which is powerful,fast dynamic response, harmonic eurrent small in charge and discharge current, has good promotional value.
