The optimal tracking strategies for two-axis PV system

This paper deals with two-axis tracking system of photovoltaic (PV) systems. The new method for determining the optimal trajectories of the tracking system is proposed. The optimization goal is the maximum of electric energy production in the PV system, considering the consumption of the tracking system. The determination of the tracking system trajectories is described as a non-linear and bounded optimization problem. The stochastic search algorithm called differential evolution is used as an optimization tool. Streszczenie. Artykul przedstawia system dwu-osiowego sterownia systemem fotowoltaicznym. Zaproponowana zostala nowa metoda określania optymalnej trajektorii systemu. Celem optymalizacji jest uzyskanie maksymalnej energii wyprodukowanej w systemie fotowoltaicznym z uwzglednieniem wydatku energii na system sterowania. Określenie trajektorii systemu stanowilo rozwiązanie nieliniowego problemu z ograniczeniami. Jako narzedzie zastosowano algorytm stochastyczny ewolucyjny.(Optymalne strategie sterowania dwuosiowym systemem fotowoltaicznym)
