Design and experimental verification of advanced control strategies to provide ancillary services with a bidirectional Vehicle-to-Grid (V2G) inverter

Vehicle-to-Grid (V2G) may contribute significantly to supporting renewable electricity grids in the future. In addition to flexibly feeding back energy into the grid, V2G inverters could also provide ancillary services to actively stabilize the grid. This poster presents different controller structures for providing ancillary system services with bidirectional AC/DC inverters, such as virtual inertia, frequency, and voltage control. After providing examples of the controllers, we verify them on our prototype and discuss the measurements. The results show that V2G inverters can indeed contribute to grid stabilization.
