Abstract :
Maximum power point trackers (MPPTs) are required to ensure optimum utilization of photovoltaic (PV) arrays in renewable energy systems, both as stand-alone and as supplementary sources of energy. In this paper, a MPPT algorithm is presented based on the perturb and observe (P & O) approach, implemented with an adaptive perturbation step size to allow fast convergence to the required operating point.
