Abstract

Zgrade i ostale rezidencijalne jedinice su veliki potrošači energije te su kao takve pogodne za ostvarivanje ušteda. Najveće uštede postižu se optimalnim korištenjem energije, a pri tom je u obzir bitno uzeti razne podatke. Nije svejedno od kojih materijala su građeni zidovi, kakvi se uređaji koriste te koliko često. Kako bi se optimalno upravljalo energijom rezidencijalnih jedinica, potrebno je promatrati i njihove korisnike. Znajući njihov dnevni raspored i boravak u određenim prostorijama, zna se kada i koliko često treba paliti ili gasiti pojedine uređaje, pa tako i samo grijanje, odnosno hlađenje. Dobar program za simulaciju potrošnje energije je IDA-ICE program jer omogućuje i grafički prikaz potrošnje. On služi kao priprema za modelsko prediktivno upravljanje (MPC). Modelsko prediktivno upravljanje je implementirano u Matlabu te se tako ostvarila optimalna potrošnja energije. Da bi se to dokazalo, projektiran je i histerezni regulator s kojim se dobila veća potrošnja. Cost benefit analizom zaključeno je da je, ako u rezidencijalnoj jedinici postoji dobro razvijeni sustav, isplativije implementirati modelsko prediktivni regulator, no ako sustav nije spreman za takvu nadogradnju, dobro je imati i histerezni regulator jer i on omogućuje značajne energetske i financijske uštede.

Abstract (english)

Buildings and other residential units are large energy consumers and as such are suitable for saving. The greatest savings are achieved by using optimal energy, and it is important to take various data into account. It is not the same of what material the walls are made, what equipment residents use, and how often. In order to optimally manage the energy of residential units, it is also necessary to observe their users. Knowing their daily schedule it is known when and how often some appliances should be turned on or off, the same is with heating or cooling. A good energy-saving simulation program is the IDA-ICE program, as it also enables graphical consumption display. It is used as a preparation for model predictive control (MPC). Model predictive control was implemented in Matlab and thus achieved optimum energy consumption. In order to prove this, a hysteresis controller was also designed with which observed zone consumed more energy. Cost benefit analysis concluded that, if there is a well-developed system in the residential unit, it is more cost-effective to implement a model predictive regulator, but if the system is not ready for such an upgrade, it is also beneficial to have a hysteresis controller because it also provides significant energy and financial savings.
