MATLAB Simulation of V2G and G2V Operation with Three-Phase Grid | dq Control | LCL Filter | SOC Tracking
 
Experience a complete bidirectional EV–Grid interaction model built in MATLAB/Simulink, featuring Vehicle-to-Grid (V2G) and Grid-to-Vehicle (G2V) operations using dq-axis feed-forward decoupled control. This professional simulation model is ideal for M.Tech/PhD scholars, EV researchers, and power-electronics engineers working on smart grid integration, EV chargers, and inverter control.
 
🚗⚡ Product Description
 
This advanced Simulink model demonstrates seamless bidirectional power transfer between an Electric Vehicle (EV) battery and a three-phase grid using an LCL-filtered Voltage Source Inverter (VSI). The model implements synchronous dq-frame current control, ensuring:
 
Stable real and reactive power regulation
Unity power factor
Smooth charging/discharging transitions
Low THD grid-connected current
 
The control strategy uses feed-forward decoupling, PI controllers, Park transformation, PWM modulation, and a dynamic SOC estimation module. The system is validated under V2G, G2V, and dynamic mode-transition scenarios.
 
This ready-to-use model is fully editable and perfectly suited for EV smart charger research.
