Abstract

This paper presents an on-line maximum power point tracking (MPPT) algorithm for a stand alone photovoltaic system. The proposed algorithm determines approximately the maximum power point of a PV array for any temperature and solar radiation level. The proposed algorithm is so simple that it needs only an on line values of PV array output current and voltage which can be obtain easily by using just current and voltage transducers. The algorithm does not require the measurement of temperature and solar radiation or a PV array model that is most used in look up table based algorithm. The proposed algorithm has simple structure and provides acceptable results.
