Coordinated Charging Strategy for Electric Vehicle Charging Station Based on Demand Prediction

This paper studies the coordinated charging strategy of an electric vehicle (EV) charging station to achieve different objectives. The coordinated charging strategy considers not only the currently connected EVs but also the EVs will be connected to the charging station. The future charging demand is predicted, which is formulated in the form of a storage-like aggregated model. And a conseivative prediction method is proposed to consider uncertainty. An optimization model is built to obtain proper charging schedule which is solved as a rolling optimization problem for real-time control. Simulation results validates the effectiveness of the proposed model and solution method.
