Abstract:Določitev pretokov energije predstavlja temelj sodobnih sistemov vodenja distribucijskih omrežij. Zato moramo zagotoviti zmogljiv algoritem za določitev pretokov energije, ki hitro konvergira, ima minimalno porabo pomnilniškega prostora in predstavlja numerično robustno metodo, prilagodljivo različnim obratovalnim scenarijem. V magistrski nalogi je podan pregled metod za izračun pretokov energije. Prikazan je postopek modeliranja elementov distribucijskega omrežja – vodov, bremen ter razpršenih proizvodnih enot. Pet determinističnih metod za izračun pretokov energije je implementirano in podrobneje analizirano. Ovrednotenje in primerjava obravnavanih metod glede njihove učinkovitosti in primernosti za izračune pretokov moči v srednjenapetostnih in nizkonapetostnih nesimetričnih trifaznih distribucijskih omrežjih je izvedeno na primeru dela distribucijskega omrežja mesta Maribor.
Keywords:pretok energije, distribucijsko omrežje, trifazni nesimetrični sistem

Title:Evaluation of methods for load flow calculations in the low – voltage distribution network
Abstract:Load flow analysis represents one of the core elements in modern control of electricity systems. Therefore, it is necessary to provide efficient, numerically robust load flow algorithm with fast convergence and minimum usage of memory, suitable for variety of operating scenarios. The Master Thesis gives a review of load flow methods as well as the procedure of modeling the distribution network elements – line sections, loads and distributed generation units. Five deterministic methods, amongst presented ones, have been implemented, compared and evaluated on the low voltage part of the three – phase distribution network system. Furthermore, evaluation of implemented methods for load flow calculation of middle voltage networks has been performed on the realistic model of middle voltage part of distribution network in Maribor.
Keywords:load flow, distribution network, three – phase unbalanced system
