Abstract

Baterijski hranilniki so s svojim hitrim razvojem v zadnjih letih dokazali, da bodo v prihodnosti zmanjšali vpliv povečanja odjema, ki bo nastal predvsem zaradi elektrifikacije prometa in ogrevanja ter proizvodnje sončnih elektrarn. V diplomski nalogi so predstavljene pomembnejše lastnosti hranilnikov, med katere prištevamo kapaciteto, izhodno moč in življenjsko dobo. Opisane so tudi ostale lastnosti in osnovna zgradba vseh baterijskih sistemov. Sledi predstavitev litij-ionskega, svinčeno-kislinskega, vanadijevega in baterijskega hranilnika na osnovi natrija. Podrobneje so opisane njihova zgradba, delovanje ter prednosti in slabosti v primeru uporabe. V drugem delu diplomske naloge je predstavljeno simulacijsko okolje, uporabljeni baterijski hranilniki in uporabljene sončne elektrarne. Opisan je tudi algoritem, ki v osnovi temelji na razbremenjevanju distribucijskega omrežja in ne na povečanju samooskrbe. Rezultati simulacij predstavljajo uporabo baterijskega hranilnika v distribucijskem omrežju v poletnem in zimskem obdobju. Dokazano je bilo, da z njihovo prisotnostjo lahko zmanjšamo obremenitev transformatorja in omejimo višino napetosti na zbiralkah v omrežju.

Secondary title: Solving the problem of overloading the distribution network with battery storage
Secondary abstract: It has been proven that battery storage units, with their quick development in the past few years, will reduce the impact of the increasing demand for electricity, which will be caused primarily by transport electrification and heating, and the production of solar power plants. In this thesis the more important characteristics of battery storage units, such as capacity, power output and shelf life are presented. Also described are other characteristics and the basic structure of battery systems. Presentation of the lithium-ion, lead-acid, vanadium, and sodium-ion battery storage units follows. Their structure, functioning, as well as the advantages and disadvantages of using them are documented in detail. The second part of the thesis is dedicated to the presentation of simulation environment as well as the battery saving units and solar power plants used. Also described is the algorithm based on reducing the burden on the distribution system and not on the increase of energy self-reliance. Presented results of the simulations show the use of a battery storage unit within a distribution system in the winter and summer period. It has been proven that the burden on the transformer can be reduced and voltage height in the system’s busbar can be limited by its presence.
