摘要
分布式发电以其投资省、发电方式灵活且不污染环境等优点,在全球范围内引起了越来越多的关注。微电网能以更具弹性的方式协调分布式电源,从而充分发挥分布式发电的优势。介绍分布式发电及微电网领域研究的诸多问题,讨论微电源、储能装置、逆变装置及隔离装置中需要研究的问题,并从电力系统应用的角度分析微电网的控制和保护、安全稳定运行、电能质量、运行及接入标准等问题。对分布式发电及微电网研究领域未来的研究方向进行总结和展望。
Distributed generators （DGs） have following advantages： saving investment, flexibility and compatibility, and they are gaining more and more worldwide attention. Microgrids can coordinate DGs in a more decentralized way, permitting them to provide their full benefits. The background of DGs and mircorgrid technology was introduced, and a definition of microgrids was put forwards and different countries＇ achievements were described in brief. The microsources （or DGs ）, energy storing devices and separation equipments were discussed. The related problems in DGs and microgrids were introduced, then problems about the microsources, energy storing devices, inverting devices and separation equipments were discussed. Some practical problems such as control and protection, safety and stability, power quality, microgrid standards were analyzed in the point of their being applied to power systems. Finally, the trend of DGs and microgrid study was discussed.
