Abstract
Današnja elektroenergetska omrežja so ob modernih energetskih razmerah vedno bolj obremenjena ter posledično le stežka in zelo počasi sledijo zahtevam po vedno večji količini energije. Ena od možnih rešitev tega problema je v uporabi elektronskih regulabilnih naprav, ki omogočajo vpliv na obstoječ elektroenergetski sistem z minimalno modifikacijo le-tega. Naprave FACTS predstavljajo eno vrsto teh regulabilnih naprav. Osnova za raziskovanje, vključitev in uporabo teh naprav v elektroenergetskih sistemih (EES) je analiza računanja pretokov moči oz. energije (angleško: »load flow« ali »power flow analysis«). Pretoke energije računamo z različnimi metodami na osnovi matematičnih modelov. Kot najbolj uspešna metoda za izračun pretokov energije se izkaže numerična iteracijska metoda Newton-Rhapson. V pričujočem delu bomo spoznali nekaj najpogostejših regulabilnih naprav FACTS in jih kasneje poskušali implementirati tudi v izračun pretokov energije. Programiranje pretokov moči ni mogoče brez ustreznih programskih orodij. Tukaj bomo omenili programa Matlab in Matpower, ki sta služila pri pisanju programske kode in preverjanju njene pravilnosti. V tem diplomskem delu predstavimo program za izračun pretokov energije, katerega delovanje in funkcionalnost smo preverili z uporabo programa Matpower.

Title:Development of new method for modelling controllable devices in load flow programs
Abstract:
In today's modern energy situation electricity grids are increasingly overloaded and consequently, it is difficult to follow ever increasing demands for amounts of energy in such circumstances. One possible solution to this problem is the use of electronic regulating devices, which allow the impact to the existing electric power system with its minimal modification. One type of these regulating devices is represented by the FACTS devices. The exploration, integration and use of these devices in electric power systems (EPS) are based on the analysis of the power flow or energy flow calculation. Power flow is calculated by using different methods based on mathematical models. It turns out that the most successful method for calculating the energy flows is the numerical iterative method Newton-Rhapson. In this thesis, some of the most common regulating devices FACTS are presented and further on implemented in the calculation of the energy flows. It should be observed that the programming of the power flows is not possible without appropriate software tools. In the research, Matlab and Matpower served in writing the software code and in verifying its correctness. Further on in this thesis, the program for calculating energy flows is presented. Its performance and functionality have been verified by using the Matpower program.

Keywords:electrical grid, power system, load flow, power flow, iterative methods, electronic regulating devices, Newton - Rhapson, FACTS, Matpower
