Photovoltaic MPPT Tracking Using Perturb and Observe Method with S-Function Implementation

Photovoltaic MPPT tracking represents an effective method for tracking the maximum power point of photovoltaic cells using the perturb and observe algorithm implemented through S-function programming. This MPPT technique maximizes the power generation efficiency of photovoltaic systems by ensuring that solar cells consistently operate at their optimal working point, thereby converting more solar energy into electrical energy. The system implementation typically involves creating an S-function that periodically perturbs the operating voltage/current and observes the resulting power change to determine the direction for maximum power point convergence. The design and implementation of photovoltaic MPPT tracking systems constitute a significant research direction in the photovoltaic field, where researchers continuously explore and improve this technology to advance the development and application of solar power generation. Key programming aspects include implementing the perturbation logic, power calculation algorithms, and decision-making functions within the S-function framework to achieve real-time MPPT control.
