Research on Maintenance Strategy of Distribution Network based on Monte Carlo Tree

The distribution network has the characteristics of many endpoints, large quantity and wide area. The frequent failure of distribution equipment seriously affects the reliability of the system and the use of users. Regular manual maintenance every year brings unnecessary maintenance costs. In addition, different maintenance schemes have a great impact on the overall health of the power grid and user experience. The maintenance problem of distribution network is the analysis of typical stochastic problem, and it is difficult to find the best maintenance plan. This paper proposes a research method of maintenance strategy based on Monte Carlo tree search method, presents the maintenance strategy search algorithm of Monte Carlo tree. Finally, the Monte Carlo tree generation process is studied based on the total maintenance cost of three years.
