Three-Phase Photovoltaic Grid-Connected Simulink Simulation Model

This three-phase photovoltaic grid-connected Simulink simulation model comprises a PV array model and grid-side control system. The PV model typically implements maximum power point tracking (MPPT) algorithms like Perturb and Observe, while the grid-side control incorporates phase-locked loops (PLL) and PWM modulation techniques for inverter synchronization. The model can be extended to include additional components such as battery energy storage system (BESS) models with charge/discharge controllers, enabling studies on energy buffering and peak shaving capabilities. Further enhancements may involve detailed inverter modeling with IGBT/MOSFET switching characteristics and transformer implementations including magnetization curves and winding configurations. Advanced control strategies like droop control, reactive power compensation, and fault ride-through algorithms can be integrated using MATLAB Function blocks or Stateflow diagrams. Through these expansions, the model's accuracy and practicality can be significantly improved, providing a robust platform for photovoltaic grid integration research and system optimization studies.
