Electric vehicles (EVs) can be used as distributed energy storage devices to provide to the smart grid different regulation services. However, to have enough impact on the grid, the trend is to jointly manage a set of EVs by means of a new stakeholder called an aggregator. Knowing the availability, mobility habits, and state of charge (SOC) of each EV battery, the aggregator performs the allocation of an active and/or reactive set-point to each EV within a time slot. This paper aims to propose reference charger currents for each EV from the individual set-point received by an aggregator. Control strategies for bidirectional active power control are compared under ideal and distorted source conditions. The control of the individual electric vehicle charging processes is decentralized, while a separate central control deals with the power transfer from the AC grid to the DC bus. The electric power exchange does not rely on communication links between the station and vehicles, and a smooth transition to vehicle-to-grid mode is also possible. The GSS has multiple Discharging Units (DUs), which transfer active and reactive power from EVs’ batteries to the grid. In this paper, a fuzzy-based control method is developed for EVs which regulates the active and reactive power for grid support. The active and reactive power flow from GSS to the grid is based on the node voltage and amount of energy available in the GSS. Simulations are performed in Matlab/Simulink to illustrate the behavior of the station. The results show the feasibility of the model proposed and the capability of the control system for fast DC charging and also vehicle-to-grid.
