Effect of Distributed Generation on Power Supply Reliability of Distribution Network

Distributed Power take advantage of clean new energy sources, combined with the actual situation of the country, flexible and efficient power generation, has been valued by all countries of the world. Distributed generation in the power system is used widely on the existing distribution network system to produce a far-reaching impact. DG access to the distribution network, to ensure the reliability of its contribution to the distribution grid, distribution network automation and protection put forward higher requirements. In this paper, distributed power at different voltage levels with wiring grid, DG access distribution network access point, the access distribution analysis DG way impact on the reliability of the power grid and power distribution network, to incorporate DG Research on Protective Relaying algorithm for Distribution provides after a theoretical basis.
