The Evaluation Method of Tunable Potential of Electric Vehicle Considering Multi-Time-Step Coupling

The charging behavior of electric vehicles (EVs) is random. Its adjustable ability is uncertain. EV's tunable potential needs to be evaluated before using the adjustability of EVs. However, the existing research fails to fully consider the coupling relationship between the adjustable ability of each time step of EVs. The results evaluated individually for each time step are too optimistic. Therefore, a tunable potential evaluation method for EVs considering multi-time-step coupling is proposed in this research. An evaluation model of the tunable potential of EVs considering multi-time-step coupling is established by analyzing the influence of the coupling relationship between different time steps on the regulation ability of EVs. Particle swarm optimization (PSO) is applied to verify the validity of the method.
