Determine The Capacity Of Distributed Power Distribution Network And Access

Distributed generation has been widely admitted as a cheap, efficient and cleaning power and will be an important part of energies in the future. In order to meet the continuously increasing demand for electricity, many distributed generators were connected to existing power systems, which made a model capable of not only computing the maximum penetration level of connected distributed generators but also evaluating the influence of their connections extremely necessary.Distributed generation has an effect on existing power systems, meanwhile incorporating distributed generators will bring a series of technical problems, one of which is protection, DG's interconnection makes distribution network become network type of many electrical sources and brings about protection not to operate normally. The paper sets about this problem to study in order to work out it.The paper discusses emphatically suffered efficiency of distribution network by DG, and introduces the computing of level of penetration.The last part introduces the process of incorporating DG.
