Simulation and analysis of a PV system using a PI controller for a boost converter and ameliored P and O MPPT algorithm

The production of photovoltaic energy has increased over the last decades. The maximum power point tracking (MPPT) strategy is used because it is always crucial to improve energy efficiency by operating the photovoltaic (PV) system at its peak power under all conditions of insolation variations and temperature. The main objective of this article is to develop a technique for improving and optimizing the control performance of a system composed of a photovoltaic panel, a boost converter, a PI controller, and a load, and to compare the standard Perturb and Observe (P&O) algorithm to the modified P&O approach employing a PI controller to extract the PV module's maximum power.
