Energy-economic feasibility of modern microgrids

Zadatak ovoga rada bio je shvatiti suvremene mikromreže kao aktivni distribucijski sustav, upoznati se s njezinim osnovnim komponentama, načinom rada, prednostima ali i nedostacima. Također osim teorijskog dijela u kojemu su obrađeni svi prethodno spomenuti zadaci, izrađeni je i praktični dio u programskom paketu Homer. U praktičnom dijelu izvršena je energetskoekonomska analiza za neautonomnu mikromrežu, te ekonomska analiza u slučaju prelaska u autonomni rad. Cilj ove analize bilo je ispitivanje ekonomsko energetske izvodljivosti izgradnje mikromreže za grad Zaprešić u oba načina rada. Grad Zaprešić je iskorišten kao primjer jer spada u osviještene gradove svoje energetske autonomne budućnosti. Dobiveni rezultati daju naslutiti potrebu za osmišljavanjem nacionalnih regulatornih funkcija s različitim modelima subvencioniranja.The subject of the thesis is the understanding of the advanced microgrids that act like an active distribution system, the insight to their basic components, mode of operation and their comparative advantages and disadvantages. The theoretical part elaborates the previously described thesis. Moreover, the practical part was made in the software package Homer. The practical part contains energy-economic analysis for nonautonomous microgrid, and economic analysis in the event of shifting to autonomous operating system. The aim of the analysis was to test, wheather the creation of microgrid operating on previosly mantioned modes, in the Zaprešić town was economically and energeticlly efficient. The town of Zaprešić was taken into consideration because it is already aware of the possibility for energeticlly autonomous future. The obtained results imply the need for developing nacional regolatory functions with different subsidisation models
