Reliability analysis of distributed system with DGs

With distributed generation technologies becoming more and more sophisticated and the progressive development of distribution automation technology, the application of distributed generation in distribution power system is gradually broad and diverse. This paper first lists the common operation modes of distributed energy sources, then analyzes the different characters of distributed generation running either as backup energy sources or as part of a microgrid, and finally develops a reliability evaluation method for distribution network containing distributed generation running in two different modes separately. The application on RBTS system shows the feasibility and accuracy of the proposed method.
