The invention is suitable for the technical field of power distribution network operation optimization, and provides a collaborative optimization method of an active power distribution network considering an electric vehicle load, and the method comprises the steps: firstly, proposing a generative adversarial network based on gradient penalty and a Wasserstein distance, and enabling the generative adversarial network to be used for generating a typical charging scene of an electric vehicle and describing the uncertainty of the charging load of the electric vehicle; secondly, the active-reactive operation domain of the electric vehicle is analyzed, and the reactive compensation capability of the charging station is researched; then, by taking the lowest total cost, the minimum node voltage deviation and the minimum renewable energy abandoned consumption as targets, constructing a multi-target active-reactive collaborative optimization model, and analyzing the operation stability of the power distribution network after the uncertainty of the electric vehicle is aggravated; and finally, solving the model by adopting a niche multi-target particle swarm optimization algorithm. Example analysis shows that the method reduces the network loss of the power distribution network by 23.12%, the overall voltage is raised to more than 0.95 p.u., the economical efficiency of the system is improved, and meanwhile, the voltage boundary crossing phenomenon is effectively reduced.
