Abstract
Prisutnost obnovljivih izvora energije u elektroenergetskom sustavu je sve veća, te dolazi do modernizacije sustava u kojem sve više dominiraju inverteri. U takvom sustavu javlja se problem deficita inercije koja je neizostavna stavka kod velikih sinkronih strojeva. U slučaju poremećajnih prilika kod takvih sustava dolazi do veće promjene brzine pada frekvencije s čime se narušava stabilnost sustava. Kao rješenje problema s deficitom inercije u sustavu napravljen je koncept virtualne inercije. Taj koncept predstavlja kombinaciju upravljačkih algoritama, OIE, BSEE i energetske elektronike, te tako nastoji oponašati inerciju konvencionalnog EES-a. U ovom diplomskom radu pružena su tehnološka rješenja za implementaciju virtualne inercije u EES, te su provedene simulacije gdje se promatra utjecaj BSEE kao pružatelja virtualne inercije. Uz pomoć računalnog alata PowerFactory provedene su simulacije utjecaja BSEE kao pružatelja virtualne inercije, gdje su dobiveni očekivani rezultati. Implementacijom BSEE u EES postignuto je povećanje inercije, smanjenje brzine promjene frekvencije i točke maksimalnog odstupanja frekvencije.
Abstract (english)
The presence of renewable energy sources in the power system is increasing, and it's coming to modernization of the system in which inverters dominate more and more. In that kind of system the problem of inertia deficit arises, which is an indispensable thing for large synchronous machines. In the event of disturbances in such systems, there is a greater ROCOF, which disturbs the stability of the system. As a solution to the problem of inertia deficit the concept of virtual inertia was created. This concept represents a combination of control algorithms, renewable energy sources, battery storage systems and power electronics, and thus tries to imitate the inertia of conventional power systems. In this thesis, technological solutions for the implementation of virtual inertia in power system were provided, and simulations were carried out where the influence of battery storage systems (BSS) as a provider of virtual inertia was observed. With the help of the computer tool PowerFactory, simulations of the influence of BSS as a provider of virtual inertia were carried out, where the expected results were obtained. By implementing BSS in power system, an increase in inertia, a decrease ROCOF and the point of maximum frequency deviation were achieved.
