摘要
结合交流、直流微网各自优点以及中国分布式电源、储能装置能量输出特点和中国负荷的供电需求,笔者介绍了交直流混合微网的优点及我国的微网技术的发展,分析了国内外交直流混合微网的研究现状及发展趋势。根据某科技产业园的负荷和电能质量需求,提出了适合中国优质电力产业园区供电需求的交直流混合微电网的技术方案;在现有微网技术研究基础上,讨论了中国交直流混合微网的关键技术和研究方向。
Considering the advantages of respective AC and DC microgrids, the output characteristics of distributed power supply and energy storage devices, and the power supply demand for load in China, this paper introduces the virtues of the AC-DC hybrid microgrid and its development in China, and analyzes its research status and development trend in the world. According to the load and power quality requirements of a science and technology tech industrial zone, an AC-DC hybrid microgrid technical scheme of high quality power supply for Chinese industrial zones is proposed. In addition, the key technologies and research direction of Chinese AC-DC hybrid microgrid are discussed on the basis of the existing research on microgrid technology.
