Adaptive Operation Strategies for Electric Vehicle Charging Stations

Abstract

Several electric vehicle (EV) charging algorithms have been recently suggested to meet different optimization objectives in power grids. In this paper, a holistic mechanism is proposed to manage the operation of EV charging stations (EVCSs). The proposed framework offers adaptive operation strategies for the EVCS operators to effectively manage the EVCS under different penetration levels of EVs, considering both normal operating conditions and restoration processes during interruptions and emergencies. The performance of the proposed approach is tested with real data and numerically analyzed on the system operational costs under different EV and PV penetration scenarios. We also demonstrate that the proposed adaptive operation mechanism could bring significant advantages to the operation and control of power grids when facing different operating conditions.
