Optimization algorithms applied for determining the operation states required for reliability calculation of the power system operation

Za zagotovitev zanesljivosti obratovanja elektroenergetskega sistema (EES), mora imeti upravljalec elektroenergetskega sistema na voljo podatke o zanesljivosti obratovanja EES. Že nekaj let se podatke pridobi z izračuni v programskim orodju NEPLAN. Eden izmed vhodnih podatkov za izračun zanesljivosti obratovanja v NEPLAN-u je tudi obratovalno stanje EES (proizvodnja, poraba in prenos el. energije). Ker vsaka kombinacija proizvodnje, porabe in prenosa predstavlja svoje obratovalno stanje, je treba določiti karakteristična obratovalna stanja EES. Karakteristično obratovalno stanje se lahko določi iz vnaprej določenih meja pasov moči iz niza podatkov (proizvodnja, poraba in prenos el. energije). V magistrski nalogi so določena karakteristična obratovalna stanja, ki služijo za nadaljnjo analizo zanesljivosti obratovanja elektroenergetskega sistema. Obratovalna stanja so določena z uporabo različnih optimizacijskih algoritmov (DE, GA in PSO) v programskem paketu MATLAB. Predstavljena je primerjava določitve različnega števila karakterističnih obratovalnih stanj.To ensure operation reliability of electric power system (EPS), an operator of EPS needs to have information about its reliability at his/her disposal. For a couple of years now, we have been able to obtain data with calculations in NEPLAN software. One of the ingoing information for calculation of operation reliability in NEPLAN is also operating condition of EPS (production, use and transfer of electric power). Because every combination of production, use and transfer represents its own operating condition, it is necessary to determine typical operating conditions of EPS. Typical operating condition can be determined by in advance specified limits of power zones from the sequence of data (production, use and transfer of electric power). In this master’s thesis typical operating conditions are determined, which serve as a means of further analysis of operation reliability of EPS. Operating conditions are determined by the use of different optimization algorithms (DE, GA, PSO) in MATLAB software. A comparison of determining different number of typical operating conditions is presented
