The invention relates to the field of new energy vehicle charging station operation strategies, and discloses a V2G electric vehicle charging station charging and discharging decision optimization method and device. Constructing a new energy vehicle charging station interaction environment based on a V2G technology; a state variable, an action variable and a reward function of reinforcement learning are set, and the reward function is provided with a plurality of optimization objectives, so that benefits of charging pile operators, power grid operators, users and the like can be balanced, and global optimization is realized. An SD3 algorithm is adopted to construct an electric vehicle charging station charging and discharging decision-making model based on reinforcement learning, an optimal electric vehicle charging station charging and discharging decision-making model is obtained through training, and an optimal charging and discharging scheduling scheme is obtained through calculation according to real-time data and the optimal electric vehicle charging station charging and discharging decision-making model. According to the method, better performance can be obtained under the condition of fewer training samples, and the reliability of intelligent decision making and the stability in the training process can be ensured in a dynamic environment. Decision strategies in a complex environment can be automatically learned, and the burden of manual rule design is relieved.
