Fuel Cell V2G for Smart Grids: System Architecture Analysis

Abstract

The primary goal of the study is a part of the integration of Fuel Cell Vehicles (FCVs) with Vehicle-to-Grid (V2G) technology, thus showing the potential for the energy of the vehicle to contribute toward the electrical grid. This study primarily focuses on the system to integrate low-voltage energy from FCVs to the higher-voltage grid. This is why a single-switch DC-DC converter conducts the boosting of the voltage for using the fuel cell in conjunction with the mains grid, while at the same time the energy transfer process is very smooth, achieving an optimized power output. The system allows for 10 kW fuel cell which can feed both homes and feed back into the electrical mains at 220V/50 Hz. In any case where the demand back home is low, all the surplus power goes to the grid, and the difference may be supplemented whenever the demand peaks high than what the FCV could feed to it
