Abstract

The invention discloses an electric vehicle charging station planning method and system considering charging demands, and the method comprises the steps: carrying out the simulation to obtain the charging demands of an electric vehicle at each demand point in each time period, and building a charging station planning model with the minimization of the annual loss of a charging station and the minimization of the user loss as a target based on the charging demands; the charging station planning model is solved coarsely, an electric vehicle charging station initial planning scheme including initial site selection points and the number of rapid charging piles and slow charging piles of the initial site selection points is obtained, finally, the electric vehicle charging station initial planning scheme serves as an initial population of a whale optimization algorithm, and the whale optimization algorithm is adopted for searching and optimizing, so that the electric vehicle charging station initial planning scheme is obtained. And a final electric vehicle charging station planning scheme is obtained. According to the method, the benefit maximization of the operator and the user is realized at the same time, and the solving performance and the convergence characteristic are effectively improved.
