Original scientific paper This paper presents an optimization of photovoltaic water pumping system (PWPS) considering the reliability criteria and economic aspects. In this way loss of load probability (LLP) as reliability criteria and life cycle cost (LCC) as economic criteria are used to simulate the performance of the PWPS. The sizing of a photovoltaic pumping system means the sizing of the photovoltaic module numbers and water tank storage capacity in terms of storage days. In the proposed

In addition, for preserving the diversity in the archive of Pareto solutions, the crowding distance operator is used. This attribute gives more flexibility to the planner for choosing the best final scheme among the obtained solutions. Of course in order to decision making, a fuzzy based NSGAII method is applied in this paper to select the favored solution among non-dominated solutions. Nova računalna metoda za tehno-ekonomsku analizu sustava fotonaponom napajane vodene pumpe bazirano na neizrazitoj logici. U radu je predstavljen optimizacijski problem upravljanja sustavom fotonaponom napajane vodene pumpe (FNVP) koji uzima u obzir kriterij pouzdanosti i ekonomski aspekt. Tako su vjerojatnost gubitka snage kao kriterij pouzdanosti i cijena životnog ciklusa kao ekonomski kriterij odabrani za simulaciju rada FNVP sustava. Dimenzioniranje FNVP sustava svodi se na dimenzioniranje broja fotonaponskih modula i kapaciteta spremnika vode u smislu dana opskrbe vodom. U predloženom algoritmu, nedominantna (Pareto optimalna) rješenja se pohranjuju u eksternu bazu i ažuriraju u svakoj iteraciji. Dodatno, za očuvanje raznolikosti baze Pareto rješenja koristi se crowding distance operator. Ta karakteristika daje veću fleksibilnost projektantu u odabiru najboljih parametara sustava meîu dobivenim rješenjima. S ciljem odabira jedinstvenog rješenja u skupu nedominantnih rješenja u radu je korišten genetski algoritam sortiranja nedominantnih rješenja. Ključne riječi: energija sunca, fotonaponom napajana vodena pumpa, vjerojatnost gubitka snage, cijena životnog ciklusa, NSGAII baziran na neizrazitoj logici
