Abstract
Zaradi direktiv glede obveznih deležev proizvodnje električne energije iz obnovljivih virov, je tematika regulacije napetosti zopet aktualna. Razpršeni viri povzročajo dvige napetosti v omrežju, ki jih s klasično regulacijsko shemo ne moremo zaznati in regulirati. Najti je potrebno boljši način za regulacijo napetosti. V tem delu sta preverjena dva možna načina regulacije napetosti v omrežju z velikim deležem razpršenih virov. Pri prvem načinu podpremo klasično regulacijo z nameščanjem SN/NN regulacijskih transformatorjev, pri drugem uporabimo centralni način regulacije, kjer napetost reguliramo glede na meritve napetosti iz večih točk omrežja. V modeliranem distribucijskem omrežju postopoma povečujemo moč razpršenih virov in analiziramo napetostne razmere v različnih delovnih točkah. Na koncu podamo mnenje o tem, kateri način regulacije je za obravnavano omrežje primernejši.

Title:Voltage control in distribution networks with high share of distributed energy sources
Abstract:
Because of directives which are determining the mandatory shares of energy generated from renewable sources, the voltage regulation topic is current again. Distributed generation sources are causing voltage raises in the grid which can not be detected and solved with the traditional regulation scheme. A better way to regulate voltage has to be found. Two approaches to this problem are checked within this thesis. In the first approach we check the traditional scheme where we add MV/LV on-load tap changers where needed and the second approach is a central principle of voltage regulation which regulates based on the measurements of voltage from different points of the network. In the model of our utility network we gradually increase the power of distributed generation and analyze the voltage conditions in different working points of the network. We conclude with an opinion about which voltage regulation priciple is more suitable for our case.

Keywords:voltage regulation, distributed generation, on-load tap changer, central regulation
