智能微网在分布式能源接入中的作用与挑战

The Role and Challenge of Smart Mircogrid in the Integration of Distributed Energy Resources

分布式可再生能源发电由于靠近用户侧直接供能且便于实现多能互补而受到越来越多的重视。而将分布式能源发电以智能微网形式接入到电网中并网运行,与电网互为支撑,是发挥分布式能源效能的最有效方式。文章介绍了智能微网的概念,阐述了智能微网在分布式能源接入中的作用,分析了智能微网的研究现状与发展趋势,提出了基于分布式能源接入的智能微网关键技术及挑战,绘制了智能微网的技术成熟度蛛网图和产业化发展路线图。

Due to the energy supply near user side and reliable to multi-energy utilization, distributed energy is paid more and more attention. It is one of the most efficient methods to integrate distributed energy resources into power grid in the form of smart microgrid since they can support with each other. First, the concept of smart microgrid is introduced and the role of smart microgrid on distributed energy integration is presented. Then, the research status and the tendency of smart microgrid are described. Next, the key technology and the challenge of smart microgrid are proposed. Finally, the spider net model of technology mature status and the road map of in-dustrial development of smart microgrid are drawn.
