Le résumé fourni par la source

With the access of a large number of flexible loads and distributed power sources, the operation reliability of distribution network is affected by multiple uncertain factors. In order to deal with the problems of complex and diversified distribution network structures, high degree of automation, and difficulties in quantifying reliability analysis, this paper proposes a reliability analysis method of automatic distribution network based on method, which solves the problem of unable to establish linearized expression in optimization model and find the global optimal solution with meta-heuristic algorithm. Firstly, the general calculation method of reliability index is given, then the reliability calculation method of different main station wiring modes is established, and the system reliability calculation method is proposed for the introduction of automation equipment on the low-voltage side. Finally, a 9-node model is established according to a real distribution network system to verify the effectiveness of the proposed method.
