Abstract

Zbog izazova koji nastaju prelaskom na obnovljive izvore energije potrebno je pronaći nova rješenja koja će pomoći u aktivaciji krajnjih korisnika, te podići učinkovitost sustava. Cilj ovog rada je izraditi mješoviti cjelobrojni linearni model vjetroelektrane i energetske zajednice, te ih udružiti u dvorazinski model kako bi se provjerila isplativost njihove suradnje. Ideja iza suradnje je ta da energetske zajednice mogu pomoći s uravnoteženjem odstupanja vjetroelektrana, na način da vjetroelektrana svojim odstupanjima trguje prvo s energetskom zajednicom prije no što ih namiri na tržištu. Model dakle mora odrediti optimalnu cijenu i količinu razmjene, kako bi profit vjetroelektrane bio što veći, a trošak energetske zajednice što manji. Rezultati dobiveni u radu pokazuju da se njihovim udruživanjem zaista ostvaruju uštede. Također određeno je i koji je optimalni odnos veličine vjetroelektrana i energetskih zajednica kod ovakve suradnje.

Abstract (english)

Due to the challenges arising from the transition to renewable energy sources, it is necessary to find new solutions that will help in the activation of end users and increase the efficiency of the system. The aim of this paper is to create a mixed integer linear model of a wind power plant and an energy community. Those models are then combined into a bilevel model in order to verify the profitability of their cooperation. The idea behind the cooperation is that the energy communities can help with balancing the deviations of wind power plants, in such a way that the wind power plant trades its deviations first with the energy community before settling them on the market. The model must therefore determine the optimal price and amount of exchange, so that the profit of the wind power plant is as high as possible, and the cost of the energy community is as low as possible. The results obtained in the work show that savings really are achieved by combining them. It was also determined what the optimal size ratio between wind power plants and energy communities is for this kind of cooperation.
