Research On Reliability Of Power Grid With Distributed Generation

First, the reliability theory of distribution network is introduced and the reliability model of single component of distribution system is established. Then, the distribution function of wind generation and PV are established by using probability theory and uncertainty modeling method. And then the method of calculating reliability the distribution network within distribute generation is introduced. On the base of method, the characteristics of the results of the uncertainty calculation method are expounded and the average of the two indexes of LOLP and EDNS is chosen as the basis of the subsequent calculation. Finally, we give the reliability of distributed network within different types, different capacity and different position locating of distributed generation.
