摘要
微电网的储能变流器采取灵活的控制策略,将各种能源转化后供给有需求的负荷,使微电网既能作为一个可控整体单元进行并网运行,又能独立运行,其控制策略对于微电网安全稳定运行尤为重要,因此,受到业内的广泛关注和研究,并取得大量研究成果。在前人研究的基础上,对储能变流器各工作模式下的控制策略进行分析和归类,并对各控制策略优缺点进行总结,同时列出目前微电网系统及储能变流器应用中有待研究解决的问题,为应用于微电网的储能变流器控制策略的应用和深入研究提供参考。
The power conversion system in microgrid adopts flexible control strategy to supply the demand load after transforming various energy sources.The power conversion system enables the microgrid to be connected to the grid as a controllable whole unit or to operate independently.Its control strategy is particularly important for the safe and stable operation of the microgrid.Therefore,power conversion system is widely concerned and studied in the industry,and a lot of research results have been obtained.On the basis of previous studies,the control strategies under various working modes were analyzed and classified.The advantages and disadvantages of each control strategy were summarized,and the problems to be solved in the application of microgrid system and power conversion system were listed.This provides a reference for the application and further research of power conversion system control strategy applied to microgrid.
