Design & Simulation of Grid-Connected PV Inverter with MPPT and DQ Control

Описание: In this project, we implement a two-stage grid-connected photovoltaic (PV) inverter system:

Stage 1: P&O MPPT-controlled DC-DC boost converter to extract maximum power from the PV array.

Stage 2: Three-phase universal bridge inverter with DQ-axis current control synchronized via a PLL.

The system achieves:

Unity power factor operation

Total Harmonic Distortion (THD) below 3% for grid current

Efficient power extraction under varying solar irradiance and temperature conditions

This project demonstrates advanced PV inverter control strategies, including outer DC-bus voltage regulation and inner DQ current decoupling, suitable for utility-scale renewable energy applications.

🔧 Tools used: MATLAB/Simulink, PV system modeling, power electronics simulation
