20.500.12556/RUL-187207 Optimizacija stroškov obratovanja otočnega napajanja stanovanjske hiše s sončno elektrarno, baterijo in dizelskim agregatom Optimizing the operating costs of an off-grid residential power system with photovoltaics, battery, and diesel generator Diplomska naloga se osredotoča na analizo otočnega sistema, ki združuje sončno elektrarno, baterijo in dizelski agregat. Namen dela je proučiti možnost napajanja stanovanjske hiše brez priključitve na elektroenergetsko omrežje; zgraditi programsko kodo in s tem omogočiti uporabniku lastno analizo sistema ter oceniti tehnične in ekonomske značilnosti takšnega sistema. V prvem delu so opisani teoretični temelji delovanja posameznih komponent in način njihovega medsebojnega povezovanja. Na osnovi vremenskih podatkov in podatkov električne energije je izvedena simulacija obratovanja sistema. Pri tem je posebej poudarjeno dimenzioniranje moči sončne elektrarne, velikost baterijskega hranilnika in vloga dizelskega agregata, ki zagotavlja energijo v času nizkega sončnega obsevanja. Rezultati simulacije kažejo, da kombinacija sončne elektrarne, baterijskega hranilnika in agregata omogočajo pokrivanje potreb po električni energiji. Obravnavan primer je ocenjen kot stroškovno manj ugoden v primerjavi s priključitvijo na elektroenergetsko omrežje. Kljub temu pa je sistem primeren za objekte, kjer ni mogoča priključitev na omrežje. The thesis focuses on the analysis of an off-grid system that combines a photovoltaic power plant, a battery storage system, and a diesel generator. The purpose of the study is to investigate the possibility of supplying electricity to a residential house without connection to the electrical power grid, to develop a software tool that enables the user to perform their own system analysis, and to evaluate the technical and economic characteristics of such a system. The first part describes the theoretical foundations of the operation of the individual components and the way they are interconnected. Based on weather data and electricity consumption data, a simulation of the system operation is carried out. Particular emphasis is placed on the sizing of the photovoltaic power plant, the capacity of the battery storage system, and the role of the diesel generator, which provides energy during periods of low solar irradiation. The simulation results show that the combination of a photovoltaic power plant, battery storage system, and diesel generator enables the coverage of electricity demand. The analyzed case is assessed as less cost-effective compared to a connection to the electrical power grid. Nevertheless, the system is suitable for locations where a grid connection is not possible. otočni sistem sončna elektrarna baterija agregat off-grid system photovoltaic system storage battery diesel generator true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-09-09 11:40:11 2026-09-09 11:40:13 2026-09-16 12:33:59 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 62881 291289091 Fratnik_kobe_Erik_-_Optimizacija_stroskov_obratovanja_otocnega_napajanja_stanovanjske_hise_s_son.pdf Fratnik_kobe_Erik_-_Optimizacija_stroskov_obratovanja_otocnega_napajanja_stanovanjske_hise_s_son.pdf 1 FD4EDB2582FB29B0F2898F83E043C5C5 358923d83d254ab23ea16ce904883cccffd6b2595bcd38d138071290512eea19 6ef85a15-ac32-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=246705 Fakulteta za elektrotehniko 0 0 0
