The invention relates to the technical field of electric vehicles, and discloses an electric vehicle charging power distribution optimization method and device, equipment and a storage medium, and the method comprises the steps: converting a charging power optimization problem of an electric vehicle cluster into a Markov decision process; and a reward function of a Markov decision process is constructed by taking profit maximization of a charging station operator as an optimization target, a reference power scheduling strategy of the charging station is obtained by solving the Markov decision process, and the charging station operator performs power scheduling on the charging station according to the reference power scheduling strategy of the charging station. The method comprises the following steps: establishing an optimal power flow model of a power distribution network operator by taking the operation cost minimization of the power distribution network operator as an optimization target, performing optimization solution to obtain a power dispatching instruction of a charging station, and sequentially distributing charging power to each electric vehicle in an electric vehicle cluster according to the priority through the power dispatching instruction of the charging station. Therefore, the electric vehicle charging power distribution accuracy is improved, and power grid dispatching stability is ensured.
