Abstract

Cilj ovog rada je analiza višeenergijskih sustava te modeliranje krajnjih korisnika koji koriste više energetskih vektora za pokrivanje električnih i toplinskih potreba. Razvijeno je 7 scenarija koji kombiniraju različite tehnologije s odgovarajućim kapacitetima te je napravljena usporedba kroz provedbu faze planiranja razvoja sustava uspoređujući financijsku isplativost projekata. Osnova je simulacija operativnog rada sustava tijekom godine dana na satnoj razini u specifičnim uvjetima rada koja je poslužila u planiranja sustava te optimizaciji operativnog rada. Odabran je optimalan režim rada te su prikazani rezultati koji pokazuju utjecaj povećanja proizvodne rezerve i spremnika energije na razinu fleksibilnosti i robusnosti sustava.

Abstract (english)

The aim of this thesis is to analyze the concept of multi-energy systems and modelling of consumers which use different energy vectors for covering electricity and heat demands. Seven models were developed that combine different technologies with adjusted capacities and comparison was made through planning energy systems phase comparing economic profitability of projects. The framework is annual operational simulation on hourly basis in specific conditions that was used in planning and operational optimization. Optimal working regime was presented as well as results showing impact of increasing generation unit reserve and energy storage reserve on flexibility and system robustness.
