A Particle Swarm Optimization-Based Maximum Power Point Tracking Algorithm for PV Systems presents an intelligent optimization approach to enhance the efficiency of photovoltaic (PV) energy conversion systems. The project focuses on implementing a Particle Swarm Optimization (PSO) algorithm in MATLAB to accurately track the Maximum Power Point (MPP) under varying environmental conditions such as changes in solar irradiance and temperature.
Traditional MPPT techniques like Perturb & Observe and Incremental Conductance often suffer from steady-state oscillations and slow convergence under rapidly changing weather conditions. To overcome these limitations, this project employs PSO, a population-based metaheuristic optimization technique inspired by the social behavior of bird flocking, to dynamically search for the global maximum power operating point of the PV array.
The developed model simulates a PV system integrated with a DC-DC converter, where the PSO algorithm continuously updates the duty cycle to ensure optimal power extraction. The algorithm demonstrates fast convergence speed, reduced oscillations around the MPP, and improved tracking accuracy compared to conventional methods.
This project provides a robust framework for researchers, students, and engineers to study intelligent control strategies for renewable energy systems and can be extended to real-time hardware implementation.
