Abstract

Z vse večjim zanimanjem za lastno proizvodnjo električne energije se vse več ljudi odloča za postavitev lastne fotonapetostne elektrarne. Ker pa se z večjimi zahtevami po električni energiji slabša kakovost napajalne napetosti, je lahko baterijski hranilnik ena izmed možnosti za izboljšave. Cilj diplomskega dela je izboljšati rabo električne energije in znižati konično obremenitev na distribucijskem omrežju s pomočjo baterijskega hranilnika električne energije ter ustvariti realni model omrežja, s katerim lahko simuliramo realne obremenitve. Izvedena je bila analiza obremenitve transformatorske postaje, ki napaja center šol, imajo specifičen odjem električne energije. Opravili smo ekonomsko analizo obravnavanega omrežja, kjer smo primerjali ceno obračunske moči pred in po zniževanju konične moči s pomočjo baterijskega hranilnika. Za izvedbo modela, za katerega smo imeli podane podatke in meritve, smo izvedli izračune s pomočjo metode BFS (Backward Forward Sweep). Pri modelu smo preizkušali vpliv velikega bremena ali generatorja na napetostni profil.

Secondary title: Provision of ancillary services with battery energy storage system in distribution network
Secondary abstract: With the growing interest in generating their own electricity, more and more people are choosing to set up their own photovoltaic power plant. However, as the quality of the supply voltage deteriorates with higher power demands, battery storage may be one option for improvement. The aim of the thesis is to improve the electricity consumption and reduce the peak load on the distribution network by using a battery storage system and to create a realistic network model that can be used to simulate realistic loads. A load analysis was carried out on the substation supplying the center for schools with specific electricity demand. We have carried out an economic analysis of the network in question, comparing the price of the billed power before and after the peak power reduction with the help of a battery. To implement the model, for which we had the data and measurements, we carried out calculations using the Backward Forward Sweep (BFS) method. The model tested the effect of a large load or generator on the voltage profile.
