Maximum Power Point Tracking (MPPT) is a critical technology used to enhance the efficiency of photovoltaic cells. In photovoltaic power generation systems, photovoltaic cells serve as core components. By tracking the maximum power point within the system, MPPT technology maximizes power generation efficiency. One commonly employed method is the Hill Climbing algorithm, which continuously adjusts the operating voltage of photovoltaic cells to locate the maximum power point. The implementation typically involves monitoring current and voltage outputs, calculating instantaneous power, and iteratively perturbing the system operating point while observing power changes. This technology is essential for ensuring stable operation and improving power generation efficiency in photovoltaic systems. Key functions in the algorithm implementation include voltage perturbation, power calculation, and decision-making logic for direction changes based on power gradient observations.
