Abstract
The thesis evaluates the impact of increased penetration of power converters on the dynamic behaviour of power system frequency through the development of reduced-order dynamic models of converter-interfaced resources. The focus is on modelling wind turbine generators and supercapacitor energy storage for dynamic simulations of a power system with a high share of power electronic devices. The final goal of the research is to develop a low-order system frequency response model of a low-inertia power system which encapsulates the relevant dynamics of converter-interfaced resources participating in grid frequency control. Additionally, a coordinated control method for provision of fast frequency control by a hybrid system of a wind turbine and a supercapacitor energy storage was developed. Finally, some remarks on the feasibility of distributed control of energy storage assets for frequency regulation are provided based on experimental verification and testing in the University of Zagreb's Smart Grid Laboratory.
Abstract (croatian)
Disertacija procjenjuje utjecaj povećanog prodora elektroničkih energetskih pretvarača na dinamičko ponašanje frekvencije elektroenergetskog sustava kroz razvoj dinamičkih modela smanjenog reda tehnologija temeljenih na pretvaračima. Fokus je na modeliranju vjetroagregata i superkondenzatorskog spremnika energije za dinamičke simulacije elektroenergetskog sustava s visokim udjelom pretvarača. Konačni cilj istraživanja je razvoj modela niskog reda frekvencijskog odziva elektroenergetskog sustava koji uzima u obzir relevantnu dinamiku resursa priključenih preko pretvarača koji sudjeluju u regulaciji frekvencije. Dodatno, razvijena je metoda za koordinirano upravljanje vjetroagregatom i superkondenzatorskim spremnikom energije za brzu regulaciju frekvencije. Na kraju, dane su neke napomene o izvedivosti distribuiranog upravljanja spremnicima energije za regulaciju frekvencije na temelju eksperimentalne provjere i ispitivanja u Laboratoriju za napredne elektroenergetske mreže Sveučilišta u Zagrebu.
