20.500.12556/DKUM-98198 Trifazni razsmernik s funkcionalnostjo sledenja omrežju in tvorjenja omrežja magistrsko delo Three-Phase inverter with grid-following and grid-forming functionalities Proizvodnja električne energije iz obnovljivih virov spodbuja razvoj razpršene proizvodnje, saj vključuje manjše proizvodne enote, ki so priključene neposredno v distribucijsko omrežje bliže porabnikom. Za priklop teh sistemov na obstoječe omrežje so potrebni pretvorniki električne energije, ki omogočajo pretvorbo energije primerno za prenos po elektroenergetskem sistemu, pa tudi otočno obratovanje. Pri tem ločimo dva osnovna tipa vodenja pretvornikov, način sledenja omrežju in tvorjenja omrežja. Brez slednjega ni mogoče vzpostaviti otočnega obratovanja. V magistrski nalogi je predstavljen algoritem vodenja trifaznega razsmernika s funkcionalnostjo sledenja omrežju in tvorjenja omrežja, ki omogoča nemoten prehod med obema načinoma vodenja, s tem pa tudi prehod med paralelnim in otočnim obratovanjem. Delovanje algoritma vodenja je bilo preverjeno s simulacijo ter eksperimentalno z modularnim pretvornikom močnostne elektronike. The production of electricity from renewable energy sources promotes the development of distributed generation, as it involves smaller generation units that are connected directly to the distribution grid closer to consumers. To connect these systems to the existing grid, power converters are required that adapt the energy transmission within the power system or enable island operation. In this context, two basic types of converter control are distinguished: grid-following mode and grid-forming mode. The last one is indispensable to establish island operation of a microgrid. These master's thesis presents a control algorithm for a three-phase inverter with both grid-following and grid forming functionalities, allowing the seamless transition between the two control modes as well as the transition from parallel to island operation of a microgrid. The operation of the control algorithm was verified through simulation as well as by experiments performed on a modular power electronics converter. mikro omrežje trifazni razsmernik vodenje v načinu sledenja omrežja vodenje v načinu tvorjenja omrežja prehajanje med načinom tvorjenja in sledenja omrežja shema vodenja microgrid three-phase inverter grid-following control grid-forming control transition between grid-following and grid-forming operation control scheme true true false [M.
