20.500.12556/DKUM-68713 Model hitre regulabilne naprave za distribucijska omrežja Flexible alternating current transmission system devices compensator for distribution system Ena izmed možnih rešitev za izboljšanje napetostnih razmer v elektroenergetskem sistemu (EES) je vključevanje hitrih regulabilnih naprav. V samem procesu načrtovanja vključitve pa se pojavi potreba po izračunu napetostnih razmer in pretokov energije, za kar potrebujemo ustrezne modele hitrih regulabilnih naprav. V preteklosti so že bili izdelani modeli hitrih regulabilnih naprav, ki so primerni za Newton-Raphsonovo metodo. Vendar pa Newton- Raphsonova metoda ni primerna za uporabo v distribucijskih oziroma radialnih omrežjih zaradi težav s konvergenco. Zaradi naštetih vzrokov bomo v članku opisali nov model hitre regulabilne naprave, ki bo primeren za U-I metodo. Nov model hitre regulabilne naprave bo testiran na dveh testnih omrežjih, IEEE 34-vozliščnem testnem sistemu in IEEE 123-vozliščnem testnem sistemu, pri čemer bojo v sistem vključeni tudi razpršeni viri električne energije. One of the possible solutions for improving voltage conditions in an electric power system (EPS) is applying power electronics based or so called flexible alternating current transmission system (FACTS) devices. However, the appropriate inclusion of a FACTS device into the EPS is not a straightforward procedure. On the contrary, it requires several steps. One of the first steps is the power flow analysis, which requires an appropriate FACTS device modelling. In the past the models of FACTS devices for Newton-Raphson (NR) power-flow and current-injection calculation methods have been developed. The NR analysis, however, is not always suitable for distribution networks due to convergence problems. This is why new three-phase models of FACTS devices for the forward/backward sweep method are presented in this paper. Their application is demonstrated on an IEEE 34 and 123 bus test systems, in order to clearly present the approach virtues for FACTS modelling in distribution networks with included distributed generation units (DGs). modeli regulabilne naprave distribucijsko omrežje napetostne razmere pretoki energije FACTS model regulator distribution system voltage conditions power flow FACTS true true true Slovenski jezik Angleški jezik Delo ni kategorizirano 2017-10-10 13:02:25 2017-10-10 13:48:55 2022-08-01 16:13:54 2019-07-11 17:01:57 0 0 0 Str. 171-189 0000-00-00 NiDoloceno Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.31 92729089 11795796 10.18690/978-961-286-071-4.19 URN:SI:UM:DK:O3EYDHI7 Bogovic_Mihalic_SLV.pdf Bogovic_Mihalic_SLV.pdf 1 388AF0A2AB54BB9B98F11EADB3D6B9B9 87b95cd23ae3d7c0b3c68b399c484fb2521af2bab037273308fe8bf657278fcb 6d132444-7c0f-11eb-bb7a-00155d0001ca 20.500.12556/dkum/1f4ca18d-1dd5-4736-94c9-87bed32e3188 https://dk.um.si/Dokument.php?lang=slv&id=119559 RAZ_Bogovic_Jerneja_0.pdf RAZ_Bogovic_Jerneja_0.pdf 1 8E35A1094CDC7E94E36F66C79C17DEE1 98509e785bdd975a33332f7b4829243500a1a6f2a04fabe522decaf84144062a 6ddb7b67-7c0f-11eb-bb7a-00155d0001ca 20.500.12556/dkum/779905ce-a7e2-4821-929f-6128cf34a7db https://dk.um.si/Dokument.php?lang=slv&id=119585 Fakulteta za elektrotehniko, računalništvo in informatiko 0 0 0
