Algoritmo de Seguimento do Ponto de Máxima Potência para Sistemas Fotovoltaicos considerando Minimização de Erro e Derivada da Potência

ABSTRACT In this work, a new maximum power point tracking algorithm (MPPT) for photovoltaic systems is proposed. The considered system is composed by a photovoltaic panel charging a battery using a buck-type dc-dc converter. Computational simulations are carried out to compare the performance of the MPPT algorithms, analyzing the output voltage and output power behavior at the photovoltaic panel. Three evaluation scenarios were considered: with constant irradiance and temperature, randomly chosen and using real data. The results of the simulations show that the proposed algorithm provides better performance for the photovoltaic system than the main MPPT algorithms in the literature.
