Power factor correction with vehicle-to-grid STATCOM implementation

The paper describes the connection of an electric vehicle to the utility grid and using the vehicle as a part of it. A new topology is presented and verified with experimental and simulation results. The experimental schematic allows to correct power factor of the grid, by using the part of the vehicle traction system. Basically it presents a portable STATCOM solution with a battery or hybrid energy storage system. By implementing the vehicle-to-grid conception, the EV/HEV become a part of the electric grid, bringing new features and benefits. Ability to use plug-in vehicles allows making the electric grid more “smart”. With more powerful vehicles, such as trucks or locomotives, the portable power solutions could be achieved. Results presented in paper are theoretical and experimental proof of upgrade possibilities of EV/HEV infrastructure and on-board architectures. There is no complex modernization required for plugging the EV/HEV to the grid. Moreover, the present powertrains can be updated.
