Abstract
In view of the effect ofthe uncertainties of distributed generations(DGs)on the reliability of distribution net-work system,an integrated Markov model is put forward to assess the reliability considering the randomness of DG,the mechanical failure rate of DG and the starting/switching refuse rate of breaker/fuse,etc.In view of the randomness of the output of photovoltaic power,Cornish-Fisher expansion method is used to generate the standard normal distribution of sample space in order to further analyze the effect of illumination intensity's correlation coefficient on thereliability of distribution network system.The simulation analysis of anIEEE-RBTSBUS6 system shows that the reliability of distribu-tion network system is closely related to the DG access point,DG capacity and DG output's correlation coefficients.关键词
