Abstract

Tehnologije za spremanje značajnijih količina energije se trenutno razvijaju
brže nego ikada do sad. U svijetu vlada trend smanjivanja onečišćenja okoliša
proizvodnjom energije, povećanja udjela obnovljivih izvora električne energije te
općenito poboljšanje energetske učinkovitosti. Jedan od načina na koji možemo
olakšati postizanje tih ciljeva je razvoj adekvatnih spremnika energije s kojima bi
bolje gospodarili elektroenergetskim sustavom.
Rad je koncipiran u nekoliko cjelina. U uvodu je detaljnije prikazano na koji
način bi spremanje energije utjecalo na elektroenergetski sustav. U drugoj cjelini
su navedeni glavni pravci razvoja i pojedine tehnologije koje se trenutno istražuju.
U trećoj cjelini se uspoređuju dva sustava sa ekonomskog aspekta. Prvi sustav je
fotonaponska elektrana uparena sa plinskom elektranom, a drugi sustav je
fotonaponska elektrana uparena sa spremanjem energije. Na kraju se nalazi osvrt
na diplomski rad u cjelini.

Abstract (english)

Technologies for storing considerable amounts of energy are developing faster than ever before. Currently in the world, there is a trend of reducing enviorment pollution, increasing the proportion of renewables and increasing overall efficiency of the power grid. One of the ways to help accomplish those goals is with development of adequate energy storing ways so we could manage the power system better.
This thesis is conceived in several sections. In the prelude it is explained how would energy storing systems impact the power grid. In second part, different energy storing technologies and research directions are considered. Third part is about the economic comparison of of two systems. First is photovoltaic plant coupled with gas turbine, second is photovoltaic plant coupled with energy storing system. At the end, whole thesis is reviewed in the conclusion.
