A Distributed Control System for Enhancing Smart-grid Resiliency using Electric Vehicles

This paper presents a decentralized control system based on cooperative control for managing the discharging rates of plug-in electric vehicles (PEVs) during islanding mode. Since energy storage systems (ESSs) are essential for the microgrids relying on renewable energies, it is assumed that the smart microgrid (SMG) is equipped with one main ESS. It is also assumed that several PEVs are connected to the grid via bidirectional controllable chargers, considering the proliferation of PEVs. In case of islanding, the proposed method controls the discharging rates of the PEVs to decrease the output power of the main ESS. This leads to an enhancement in the grid ride-through-ability, and consequently, its resiliency since the SMG can longer supply the loads in islanding mode. The proposed method is evaluated utilizing Matlab/Simulink. According to the simulation results, the advantages and disadvantages of the proposed control system are presented and discussed.
