摘要
首先介绍了微电网的产生背景,并对微电网进行定义。其次,在对比了各国微电网的研究进展现状后,针对一个典型的微电网阐述了基本运行方式。接着介绍了微电网的电源和储能形式,并对微源的控制器特性即频率下垂曲线进行了简单的描述。微电网输配电系统也与传统电网有着明显的不同,由于低压线路参数的特殊性,需要对功率调节公式进行修正。微电网系统优化与稳定也是微电网的关键研究内容之一,初步给出了系统优化和稳定运行目标。最后,在依托电工所在新能源方面的既有成果上,提出了微电网的将来研究的重点和难点。
Microgrid is one type of future power systems put forward by foreign researchers, which has a special superiority on not only improving power quality and reliability but also relieving pressure of energy and environment. First, this paper introduces the background and definition of microgrid.Second, different countries＇ achievements are compared, and basic running mode is represented for a typical microgrid. After energy resource and storing energy being classified, a frequency-droop character is described. Obviously different from classic transmission and distribution system, microgrid has its own feature. And power adjustment formulation has been amended. System optimization and stability is one of key research in microgrid, therefore series of goal is offered preliminarily. In the end, based on achievement by IEE in new energy, emphasis is put forward for future research in microgrid.
