Abstract

Zelena energetska tranzicija i energetska kriza donose nove izazove za energetski sustav Europske Unije koji naglašavaju potrebu za smanjenje uvozne ovisnosti i potpunom dekarbonizacijom energetskog sustava. Postizanje ciljeva donosi mnoge izazove. Potrebno je očuvati gospodarstvo te očuvati i unaprijediti dostupnost energije.
Ubrzana tranzicija uključuje sve veći broj postrojenja obnovljivih izvora energije priključenih na energetski sustav. Zbog stohastičke naravi elektroenergetski sustav nije prilagođen za rad s punim potencijalom obnovljivih izvora energije. Kako bi sustav bio dugoročno održiv potrebno je izvršiti prilagodbe koje će omogućiti nesmetan rad obnovljivih izvora energije, jamčiti pouzdanu opskrbu, pritom, maksimalno smanjiti troškove prilagodbe.
Ovaj diplomski rad donosi pregled trenutnog stanja opskrbe iz obnovljivih izvora energije, pregled mogućih rješenja za prilagodbu energetskog sustava i primjer prilagodbe opskrbe na jednoj industrijskoj zoni.
Prilagodba predmetne industrijske zone temelji se na fleksibilnoj energetskoj opskrbi omogućenoj: sudjelovanjem zone na burzi električne energije, korištenjem baterijskog sustava i fleksibilnim upravljanjem bioplinskog postrojenja. Fleksibilna energetska opskrba prikazana je matematičkim modelom napravljenim u programu Matlab. Model za cilj ima prikazati način upravljanja kojim se ostvaruju minimalni troškovi opskrbe električnom energijom.
Za izradu modela opskrbe korišteni su profili potrošnje industrijske zone napravljeni na temelju dostupnih podataka o sličnim postrojenjima i izrađen je model fotonaponskog sustava industrijske zone u programu PVSol.

Abstract (english)

The green energy transition and the energy crisis bring new challenges for the energy system of the European Union, which emphasize the need to reduce import dependence and complete decarbonization of the energy system. Achieving goals brings many challenges. It is necessary to preserve the economy and preserve and improve the availability of energy.
The accelerated transition includes an increasing number of renewable energy plants connected to the energy system. Due to its stochastic nature, the power system is not adapted to work with the full potential of renewable energy sources. In order for the system to be sustainable in the long term, it is necessary to make adjustments that will enable the smooth operation of renewable energy sources, guarantee a reliable supply, and at the same time, reduce adjustment costs as much as possible.
This graduate thesis provides an overview of the current state of supply from renewable energy sources, an overview of possible solutions for adjusting the energy system and an example of adjusting the supply in one industrial zone.
The adaptation of the industrial zone is based on flexible energy supply made possible by: the zone's participation in the electricity exchange, the use of a battery system and flexible management of the biogas plant. Flexible energy supply is shown by a mathematical model created in the Matlab program. The aim of the model is to show the way of management that achieves the minimum costs of electricity supply.
To create the supply model, industrial consumption profiles of the zone were used based on available data on similar plants, and a photovoltaic system model of the industrial zone was created in the PVSol program.
