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.
