This paper introduces a novel dynamic power tracking (DPT) algorithm tailored for microinverter-based photovoltaic (PV) systems, enhancing power stability and efficiency under varying irradiance conditions. By refining the conventional voltage-step perturb and observe (P&O) approach, the algorithm minimizes power oscillations and dynamically adapts to environmental changes without reinitialization. Experimental validation confirms reliable power stabilization across various PV modules, supporting seamless integration into grid-connected systems under diverse operational scenarios.
