Abstract
Modeliran je mikro-kogeneracijski sustav s vodikovim podsustavom (gorivni članak, elektrolizator i spremnik vodika) u sprezi s obnovljivim izvorima energije, odnosno podsustavom s vjetroturbinom i fotonaponskim panelom, te dizalicom topline, takav da poslužuje električnom energijom, grijanjem i hlađenjem samostalno kućanstvo u mediteranskoj klimi. Satni model koristio se za simulaciju njegovog rada tijekom cijele godine. Primijenjena je jedinstvena strategija upravljanja energijom kako bi se postigla konfiguracija s minimalnom veličinom komponenti bez manjka ili viška proizvedene energije. Kombinacijom rada gorivnih članaka s dizalicom topline prati se električni i toplinski (topla voda, grijanje i hlađenje prostora) profil kućanstva. Analizirana su tri režima rada hibridnog sustava za posluživanje AC profila potrošnje električne energije s različitim vršnim opterećenjima (pojedinačno ili više uređaja istovremeno kroz poslijepodne ili noću/ujutro), ali s jednakom ukupnom godišnjom potražnjom. Provedenom analizom odabran je hibridni sustav s najprikladnijim posluživanjem AC profila za mediteransku klimu, te je uspoređen s najčešće korištenim sustavom sa samo baterijskom pohranom. Pokazalo se da je za pohranu energije u vodik dovoljno samo 10% više energije iz obnovljivih izvora, pri čemu je tada potrebna baterija manja za čak pet puta.
Abstract (english)
A micro-cogeneration system with a hydrogen subsystem (fuel cell, electrolyzer, and hydrogen tank) was modeled in conjunction with renewable energy sources, that is, a subsystem with a wind turbine and photovoltaic panel, and a heat pump, such that it serves an independent household in a Mediterranean climate with electricity, heating, and cooling. The hourly model was used to simulate its operation throughout the year. A unique energy management strategy was applied to achieve a configuration with a minimum size of components without a shortage or excess of produced energy. The household's electrical and thermal (hot water, space heating, and cooling) load profile is followed by combining the fuel cell with the heat pump. Three hybrid system operation modes were analyzed to serve the AC profile of electricity consumption with different peak loads (individual or multiple devices simultaneously through the afternoon or night/morning) but with the same total annual demand. Through the analysis, a hybrid system was selected with the most suitable serving AC profile for the Mediterranean climate, and it was compared with the most commonly used system with only battery storage. It has been shown that only 10% more energy from renewable sources is enough to store energy in hydrogen, and the battery required is as much as five times smaller.
