Vehicle to Grid operation of an Electric Vehicle using Model Predictive Control

By 2025 all the existing vehicles will be completely replaced by Electric Vehicles(EV) globally. Every year automotive industry introduces EVs with new features. An onboard charger with bidirectional capability makes EVs an energy storage unit. Vehicle-to-grid operation(V2G) of an EV is a promising solution for load frequency control problems. In this work Model Predictive Control(MPC) based V2G operation is proposed. In the proposed work a three-phase Active Front End(AFE) converter(AC-DC converter) with bidirectional capability is used for designing an Onboard charger. Here the optimal discrete operation of the AFE converter is based on finding desired switching states using the MPC. By using the proposed method the power converter will maintain unity power factor, sinusoidal input current, and low voltage ripple. Simulations are done using Matlab/Simulink and the results prove the efficacy of the proposed technique.
