Orderly automatic real-time charging scheduling scenario strategy for electric vehicles considering renewable energy consumption

The ORTCS (Orderly Real-time Charging Scheduling) strategy for collaborative optimization of electric vehicles and renewable energy output is proposed, which is considering the flexibility of charge and discharge in the intelligent transportation field. The strategy aims to maximize the consumption of renewable energy as while as minimize the waiting time and expense of car users. An EV (electric vehicle) once entering the charging station and being connected to the power system, the organized planning of charge and discharge is evaluated based on its initial battery SOC (State of Charge), so as to obtain the real-time schedulability level from the whole charging station point of view. According to the dispatching level and the output of renewable energy in the station's power system, the optimal plan is made for each connecting EV. (c) 2022 The Author(s).

Automated summary

This paper proposes the ORTCS strategy for collaborative optimization of electric vehicles and renewable energy output, taking into account the flexibility of charge and discharge in the intelligent transportation field. The strategy aims to maximize the consumption of renewable energy while minimizing waiting time and expenses for car users. It evaluates the organized planning of charge and discharge based on the initial battery SOC of an electric vehicle connected to the power system, in order to obtain the real-time schedulability level from the perspective of the entire charging station.
