Abstract: In order to improve the safety and reliability of distributed generation in rural power grid, a reliability evaluation method of distributed generation in rural power grid based on network partition is proposed. This method firstly constructs the output reliability model of photovoltaic and wind power distributed generation, and then, divides the rural power grid into four regions, and constructs the reliability index of distributed generation in each region. Monte Carlo simulation method is used to evaluate the reliability of distributed generation in rural power grid. The results show that compared with the average power supply accuracy of the actual distributed power supply, the error of the test results of this method is controlled within 0.2%, which is far lower than the error of the reliability evaluation of the distribution network with distributed generation and the node vulnerability evaluation method of the distribution network considering the random characteristics of the distributed generation, indicating that the proposed method can accurately evaluate the reliability of distributed power supply in rural power grid.
