Abstract
Solar-hydrogen autonomous system for supplying isolated real passive house in real climate with power energy, energy for personal transport and heating/cooling system have been established and discussed. Simulation and analysis of a model of an autonomous power system based only on a renewable source (solar irradiance) integrated with a hydrogen system for energy backup has been performed. Commercially available passive house in island of Hvar in Croatia, and real commercial components (photovoltaic module, fuel cell stack and electrolyser) were acquired. In order to minimize the level of modeling and simulation complexity, just electric - hydrogen system have been modeled and result of dynamic simulation has been presented. For heating and cooling of the house only static simulation (calculation in Excel) has been performed instead of dynamic simulation. The electric-hydrogen system is composed of a PV array integrated with an electrolyser, with a storage tank where the hydrogen is stored as compressed gas and with a PEM fuel cell stack. Such a system has no pollutant emissions and is environmentally friendly. Matlab-Simulink software has been used to design the system and to analyze its functioning during one certain day of operation. The analysis has been affected by considering three scenarios in order to simulate different situations (with and without solar irradiance) with high energy demands by the user to prove the control system function during the system operation. Simulations results show that concept, design, mathematical models and Simulink schemes work as it assumed. All of that can be used as valuable tool for passive house autonomous electric-hydrogen system design.
Abstract (croatian)
U radu je izveden i analiziran sunčevo-vodikov autonomni sustav za snabdijevanje električnom energijom izolirane realne pasivne kuće u realnim klimatskim uvjetima, energijom za osobni transport i sustavom za grijanje i hlađenje. \Napravljena je simulacija i analiza modela autonomnog sustava za proizvodnju električne energije zasnovanog samo na obnovljivom izvoru energije (sunčevom zračenju) koji uključuje i vodikov podsustav za pohranu energije. Pretpostavljene su komercijalno dobavljiva pasivna kuća smještena na otoku Hvaru u Hrvatskoj, i realne komercijalno dobavljive komponente (fotonaponski modul, svežanj gorivnih članaka i elektrolizator). Da bi se smanjila kompleksnost modeliranja i simulacije, izvršeno je modeliranje, simulacija i dan prikaz rezultata samo za dinamiku električno - vodikovog sustava. Umjesto simulacije dinamike grijanja i hlađenja kuće izvršen je samo proračun stacionarnog stanja u Excelu. Električko-vodikov sustav sastavljen je od PV polja koje je integrirano s elektrolizatorom, rezervoarom za pohranu u kojem se pohranjuje vodik u formi komprimiranog plina i svežnjem PEM gorivnih članaka. Takav sustav ne ispušta štetne tvari i prihvatljiv je za okolinu. Matlab-Simulink računalni program korišten je u projektiranju sustava i analizu funkcioniranja električko-vodikovog sustava tokom jednog određenog dana. Analiza je provedena na temelju tri pretpostavljena scenarija da bi se simulirale različite situacije (sa i bez sunčevog zračenja, uz visoke i niske potrebe korisnika za električnom energijom) i time provjerio regulacijski sustav. Rezultati simulacije pokazuju da koncept, projekt, matematički modeli i Simulink sheme funkcioniraju kako je zamišljeno. Sve to može biti korišteno kao vrijedan alat kod projektiranja autonomnog električno-vodikovog sustava za pasivnu kuću.
