Simulink verification of Robust Control Strategy for V2G Bidirectional Converter under Electromagnetic Interference

The V2G system realizes vehicle-to-grid interaction and uses the stored energy of electric vehicles as a buffer between the power grid and renewable energy. However, the differential mode/common mode interference in the bidirectional energy conversion process can have negative impacts on the power grid ecology, on-board equipment, etc. Therefore, this paper proposes a strategy combining an interference observer (DOB) and $\mathrm{H}_{\infty}$ robust control for estimating and compensating electromagnetic interference. The simulation verified its superiority in steady-state accuracy, dynamic response and anti-interference, and improved the robustness of the V2G system.
