Power Tracking Photovoltaic System Tied to Single-Phase Grid

Abstract

The photovoltaic system is one of the sustainable renewable energy cornerstones that has piqued the interest of researchers in recent years. Since environmental factors such as temperature and radiation levels change over time, the system’s productive strength is impacted. Due to the system’s decreased effectiveness as a result of these changes, a technique called Maximum Power Point Tracking (MPPT) should be utilized to improve the overall system. MPPT is a programmable control innovation that is used to achieve the optimal pool of energy possible. The Maximum Power Point Tracking algorithm in a PV system under variable irradiance and temperature is presented in this paper. For MPPT, the perturb and observe (P&O) method is proposed. The proposed technique provides faster integration with the greatest strength, resulting in a more efficient overall system. The overall system is simulated using MATLAB/SIMULINK POWER LIB, and a practical prototype is implemented in the meantime. Both findings indicate that the proposed system’s anticipated outcomes are met successfully.
