This document discusses vehicle-to-grid (V2G) technology using DC fast charging in a microgrid system. It proposes an architecture that uses bidirectional battery chargers and grid-tied inverters to enable power transfer between electric vehicle batteries and the microgrid. The system is modeled and simulated. Simulation results show that electric vehicle batteries can effectively regulate power in the microgrid using V2G and G2V concepts with DC fast charging. Harmonic analysis shows that the LCL filter maintains current distortion within IEEE limits.
