Optimal Scheduling for EV Charging Stations in Distribution Networks: A Convexified Model

摘要

A convexified model for EV charging station scheduling is proposed in this letter, which minimizes the total charging cost and the energy cost from the substation during the concerned time horizon. The model is transformed from the conventional model by using convex relaxation techniques, by which the globally optimal solution and high computational efficiency can be achieved. The proposed approach is validated by numerical simulations on a 15-bus distribution network.
