20.500.12556/RUL-181826 Priključitev sistema baterijskih hranilnikov električne energije na distribucijsko transformatorsko postajo Connection of a battery storage system to a distribution transformer station Namen zaključnega dela je obravnava možnosti razbremenitve obstoječe transformatorske postaje z uporabo baterijskega hranilnika električne energije ter analiza vpliva takšne rešitve na obratovanje elektroenergetskega sistema. V delu je obravnavana obstoječa transformatorska postaja, ki napaja hitro polnilno infrastrukturo ter fotonapetostno elektrarno. Zaradi možnosti sočasnega delovanja večjega števila električnih polnilnic obstaja tveganje, da obratovalna moč preseže dovoljene meje transformatorja. To lahko vodi v preobremenitev in zmanjšanje zanesljivosti sistema. V nalogi je predstavljeno ozadje problema, teoretične osnove baterijskih sistemov, pregled tehnologij ter vloga baterijskih hranilnikov v elektroenergetskem omrežju. Glavna tematika je projektiranje baterijskega hranilnika ter pripadajočih elektroinštalacij. Na podlagi analize obremenitev je izvedeno dimenzioniranje hranilnika z vidika nazivne moči in kapacitete ter načrtovanje priključitve na obstoječi elektroenergetski sistem. Projektiranje vključuje tudi določitev potrebnih električnih inštalacij, razdelilnih sistemov ter krmilnih in komunikacijskih povezav. V okviru naloge je izdelana projektna dokumentacija, ki vključuje električne sheme, tehnične načrte ter dimenzioniranje ključnih komponent sistema. V zadnjem delu naloge je obravnavan tudi ekonomski vidik investicije. Narejena je primerjalna ocena obravnavane rešitve z baterijskim hranilnikom ter alternativno možnostjo povečanja razpoložljive moči z dogradnjo dodatnega transformatorske postaje enake nazivne moči. The purpose of this thesis is to examine the possibility of relieving the load of an existing transformer substation by integrating a battery energy storage system and to analyse the impact of such a solution on the operation of the electrical power system. The analysed transformer substation supplies fast charging infrastructure for electric vehicles as well as a photovoltaic power plant. Due to the potential simultaneous operation of multiple fast chargers, there is a risk that the total operating power may exceed the permissible limits of the transformer, which could lead to overloading and reduced reliability of the system. The thesis first presents the background of the problem, the theoretical fundamentals of battery energy storage systems, an overview of available technologies, and the role of battery storage in modern power systems. The sizing of the battery storage system in terms of rated power and energy capacity, as well as the required electrical installations, is also addressed. The main focus of the thesis is the design of a battery energy storage system and its associated electrical installations. Based on an analysis of the load profile, the storage system is dimensioned with respect to rated power and energy capacity, and its integration into the existing electrical power system is planned. The design process also includes the specification of the required electrical installations, distribution systems, and control and communication connections. As part of the thesis, project documentation has been prepared, including electrical schematics, technical drawings, and the dimensioning of key system components. In the final part of the thesis, the economic aspect of the investment is also considered. A comparative assessment is carried out between the proposed battery storage solution and an alternative option of increasing the available capacity by constructing an additional transformer substation with the same rated power. baterijski hranilnik transformator obnovljivi viri energije ekonomska analiza investicija battery storage system transformer renewable energy sources economical analysis true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-04-16 10:05:01 2026-04-16 10:05:16 2026-05-27 10:55:58 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 63317 279515139 Metelko_Mark_-_Prikljucitev_sistema_baterijskih_hranilnikov_elektricne_energije_na_distribucijsk.pdf Metelko_Mark_-_Prikljucitev_sistema_baterijskih_hranilnikov_elektricne_energije_na_distribucijsk.pdf 1 C946CB8125A433B8157CDB700166CE47 bd7fb7b8634496c13797344086d1a7dd2603d7528dd1874767604d962afe6da3 c767a08b-396a-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=232564 Fakulteta za elektrotehniko 0 0 0
