The invention discloses a cluster electric vehicle charging behavior optimization method based on deep reinforcement learning, and belongs to the technical field of new energy vehicle optimization management. The invention relates to a deterministic strategy gradient algorithm based on double delay depths. Modeling is carried out on the power continuous adjustable charging process of the electricvehicle, an intelligent agent is trained to control the charging power, the charging behavior of the electric vehicle is optimized, the load when the time-of-use electricity price is high is transferred to the load when the electricity price is low, and the purposes of reducing the user charging expenditure and stabilizing the peak-time load of a power grid are achieved. Compared with a traditional optimization control method, the TD3 has obvious advantages in speed and flexibility, and the problems that an existing reinforcement learning method is discrete in action space, difficult in training convergence and poor in stability can be effectively solved. In order to enhance the generalization ability of the intelligent agent, noise is added on the basis of original state observation, a group of electric vehicles with different initial SOCs and different arrival and departure time are simulated, and the method is expanded to cluster electric vehicle charging behavior control.
