ANALYSIS OF VOLTAGE CONDITIONS AND LOSSES IN DISRIBUTION NETWORKS WITH DISTRIBUTED GENERATION

Delo obravnava analizo napetostnih razmer in izgub razdeljevalnega omrežja električne energije, v katerega so vključeni razpršeni viri. Pri analizi napetostnih razmer ob vključitvi razpršenih virov je prikazana primerjava med rezultati statičnega (Gredos) in poenostavljenega dinamičnega (Matlab/Simulink) modela razdeljevalnega omrežja. Rezultati kažejo velik razkorak v spremembah napetosti v stacionarnem obratovalnem stanju v primerjavi s prehodnim pojavom spreminjanja moči vira, katerim so različne vrste virov povsem različno podvržene.This diploma thesis deals with the analysis of voltage conditions and losses in an electricity distribution network with distributed generation. The analysis of voltage conditions in the distribution network with distributed generation units is performed by using the program Gredos for steady-state analysis and a simplified dynamic model build in the program package Matlab/Simulink. The results presented in the diploma thesis show a substantial difference between the voltage profiles in steady-state and transient operations caused by changing power of distributed generation units
