The invention discloses a distributed power supply planning method considering the charging load influence of an electric vehicle. The method comprises the following steps: modeling wind power, a photovoltaic generator set, a user load and the charging load of the electric vehicle; sampling the wind speed, the illumination intensity and the demand load; performing scene clustering and reduction onwind power, photovoltaic, user load and electric vehicle charging load; weighting the four indexes of the network loss, the reactive power loss, the line load and the voltage deviation to obtain a system comprehensive performance index as an index for evaluating the system performance; constructing a multi-objective distributed power supply planning model, constructing a fuzzy membership model for an objective function, and representing an optimization result by using overall satisfaction; and solving by using a hybrid search strategy combining an improved particle swarm algorithm and an interior point method. According to the invention, the reduction of comprehensive performance caused by the access of distributed energy and electric vehicles to the power grid is reduced, a power grid company sets network performance indexes according to preferences to determine the positions and capacities of the distributed power supply and the electric vehicles, and optimal economic benefits are achieved.
