Comparison of MPPT strategies in battery charging of photovoltaic systems
In photovoltaic standalone systems it is crucial to absorb most of the available energy. Thus, in order to extract the maximum power of a solar panel for a given set of climatic conditions, it is used maximum power point tracker (MPPT). The MPPT consists in a power converter which controls the solar panel voltage. In this context, this work compares the instantaneous and dynamic efficiency of three MPPT algorithms proposed in literature: perturb and observe, dP - perturb and observe and modified perturb and observe used in a photovoltaic standalone systems. The system analyzed is composted by a 48 W solar panel, a battery of 60 Ah and a charger based on a buck converter. During solar irradiance variations the algorithms presented different instantaneous efficiencies, what can produce reduction in energy absorbed during cloudy days.
