Techno-economic analysis and conceptual design of photovoltaic power plant with and without battery system for office building according to ESCO model

U radu smo se upoznali s osnovama fotonaponskih sustava i sunčevom energijom. Opisan je postupak projektiranja i odabir optimalnog fotonaponskog sustava za HEP-ovu zgradu u Karlovcu. Optimalni fotonaponski sustav izrađen je po ESCO modelu, uključujući i troškovnik. Projektiranje i simulacija su odrađeni u PVSol i RETscreen programima. Rad je zaokružen detaljnim upoznavanjem sa zakonom za otkup električne energije, te pohranom u baterijske spremnike i usporednom simulacijom s i bez baterijskih spremnika.The thesis introduces concepts of photovoltaic systems and solar energy. The process of designing and choosing the optimal photovoltaic system for HEP building in Karlovac is described. Optimal photovoltaic system is designed following the ESCO model, including a bill of quantities for building such a system. For the design and simulation of the system, PVSol and RETscreen software programs were used. The thesis concludes with comparison of two different scenarios, with and without battery storage, considering energy buyback law which is also introduced in the thesis
