Abstract

With the expansion of power grid scale, the performance bottleneck of traditional reliability assessment methods has gradually become prominent. How to improve the efficiency of reliability assessment has become an urgent problem to be solved. At the same time, the widespread access of distributed generation in the distribution network also affects the reliability of the distribution network. In view of these problems, this paper proposes an improved Warhall topology analysis method and an improved Monte-Carlo method to record fault sections, which improve the efficiency of reliability evaluation. On the basis of the improved method, the reliability index of a distribution network with DG access is calculated through a specific example, and the influence of DG access and access location on system reliability is further analyzed.
