Abstract — Grid Connected Solar Pv System Matlab Simulink Model
This project is based on a MATLAB/Simulink implementation of a three-phase grid-connected PV system and is being used as a learning platform to understand: MATLAB/Simulink implementation of a three-phase grid-connected solar PV system with MPPT, PLL synchronization, dq current control, and PWM-based inverter.
Operational Methodology & Framework
A MATLAB/Simulink model of a 108 kW two-stage grid-connected PV system featuring MPPT (P&O), dq-control, SPWM, and an LCL filter. This project presents modeling, simulation and control of a 108 kW two-stage grid-connected photovoltaic (PV) system using MATLAB/Simulink. The system integrates a DC-DC boost converter with a Perturb and Observe (P&O) Maximum Power Point Tracking (MPPT) algorithm, a three-phase Voltage Source Inverter (VSI), and an LCL filter for grid synchronization and harmonic attenuation.
Experimental Findings & Validation
The goal of this project is to ensure efficient and stable grid integration of solar power, providing high-quality sinusoidal current with minimal harmonic distortion. The system uses a current control technique in the dq reference frame for regulating active and reactive power, ensuring unity power factor operation.
