Abstract
A reactive power evaluation model is proposed to estimate the available V2G capacity of reactive power provided by EV chargers during a day considering the travelling behaviors of EV users. Firstly, a generic EV charger model (GECM) is developed to describe the reactive power response characteristic of EV charger. Then, considering the travelling behaviors of EV users, a Monte Carlo simulation (MCS) method is implemented to build the reactive power evaluation model. Finally, the available reactive power from EV chargers is analyzed and compared under two different charging strategies (dumb charging and smart charging). Simulation results show that the reactive power evaluation model can determine the available reactive power capacity for V2G along a day, which can support the operation of the power system.
