Research On The Effect Of Distributed Generation Access To Distribution Network

With the development of the new energy power,the application of the distributed generation in the power system has gradually increased.The distributed generation access to distribution network has made up for the lack of centralized power supply and increased the flexibility of the power system.But it also bring some influence to power system.In this paper,the problems of the distributed generation access to distribution network are discussed.the main results include the following aspects:Establish the typical power supply models of distribution network for the study.First,the paper analysis on influence of distributed generation access to distribution network for the distribution network stability,which include the influence to the node voltage,the different access capacity and the different types of interface etc.Second,the paper analysis on influence of distributed generation access to distribution network for the distribution network reliability.The paper discussed the distributed generation with different capacity access to different positions with the research of reliability index.Third,the paper analysis on planning and design of distributed generation access to distribution network for the distribution network.It put forward the construction principle of the economy as the main index and verified by practical examples.
