摘 要:本文介绍了英国可再生分布式发电市场现状和英国配电网(132k V^11k V)所取得的相关进展。简述了英国分布式发电相关政府法规、市场补贴机制和分布式电源入网规程。分析了高比例分布式发电对配电网造成的困难,并用实际工程案例阐述了应对方案。进而,为解决分布式发电带来的故障电流增高、电压升高和反向潮流等技术问题,列举了英国各地区试点项目应用的故障电流限值器、FACTS装置、储能设备和中压直流输电等技术方案。介绍了英国实时网络分析软件和配电系统优化技术,应用该技术可进一步释放配电网容量。This article aims to provide an overview on UK renewable distribution generation(DG)market and to present the progress and improvement made by distribution network operators(DNOs).New relevant government regulation and incentive mechanisms are briefly explained.The typical DG connection cycle is introduced.The main challenges faced by UK distribution network operators as a result of high level DG penetration and innovative solutions are discussed with project examples.To overcome common issues caused by DG like higher fault level,voltage rise,and reverse power flows,solutions are proposed such as fault current limiter,FACTS device,energy storage and DC interlinks.Also by equipping real time system analysis and planning tools,network restrains can be relieved and more network capacity can also be released.
