Reliability evaluation of distribution network with distributed generation

After DG accessed to distribution network, the structure and operation mode have great changes, larger influence on power system reliability index, so need to adopt a new reliability evaluation model and method, it proposes reliability evaluation model and method of distribution network with distributed generation, and the simulation calculation was carried out, to verify the effectiveness of the model and the algorithm, it can be seen from the simulation results that DG can change the load point and the system reliability index greatly, and the closer DG and feeder lines at the end of the load point, whose improvement effect is more obvious.
