PSO Sliding mode Based Variable step P&O MPPT in MATLAB

Introduction to MPPT

In the world of solar energy systems, the quest for maximizing efficiency and output is a continuous pursuit. One crucial aspect is the MPPT (Maximum Power Point Tracking), a method used to ensure solar panels harness the maximum available power from the sunlight. This article delves into the innovative approach of PSO Sliding Mode Based Variable Step Perturb and Observe MPPT in MATLAB.

Perturb and Observe (P&O) Algorithm

The P&O algorithm is a widely used MPPT method. Its principle involves perturbing the operating point of the solar panel and observing the change in power. Though simple, its reliance on perturbations can lead to oscillations around the maximum power point.

PSO (Particle Swarm Optimization) Algorithm

PSO, a nature-inspired optimization algorithm, is gaining traction in MPPT for its ability to efficiently track the maximum power point. Its swarm intelligence-based approach aids in overcoming local optima, enhancing the overall efficiency of solar panels.

Sliding Mode Control

Sliding mode control is a robust control methodology ensuring the system’s stability by driving the state onto a sliding manifold. When applied to MPPT, it helps in regulating the solar panel's operating point, contributing to better performance.
