Research on distribution Network Planning in the context of distributed energy Resources

Distributed energy is an important part of modern energy system. Compared with the traditional centralized energy, distributed energy has the characteristics of low carbon, rich and flexible. Based on the demands of energy diversity, simple to understand the basic concept of distributed energy first, for the development of distributed energy at home and abroad, observes, respectively study the network from the access to the distribution network line loss, the influence of the relay protection, power quality, etc, and has carried on the quantitative analysis to the influence of the network line loss, finally it is concluded that the distributed power grid line loss reduction and energy after given depends on the structure of the distribution network planning, the conclusion of the capacity such as the location of distributed energy. Therefore, in the structure planning of distribution network, the strategy of equalizing the access proportion of distributed energy and economic benefits is pointed out.
