Review of electrical energy storage systems in EPS

Diplomsko delo podaja pregled baterijskih sistemov. V uvodu predlagam rešitve, kako izboljšati obratovanje elektroenergetskega sistema s shranjevanjem električne energije. Ker sem se osredotočil na baterije in, da lahko pojasnim, v kakšne namene jih lahko uporabljamo v EES, je potrebno razumeti karakteristike in delovanje baterij ter njihovo tehnologijo. Omenil sem različne uporabe BESS, vendar sem se osredotočil na tri najbolj pogoste probleme, in sicer regulacijo frekvence, regulacijo napetosti in rezanje konic. Predstavil sem tudi največje proizvajalce baterijskih sistemov in njihove projekte.The diploma thesis is a general overview of battery systems. It starts with introduction, which presents how the power system can be improved by storing energy. My focus is on batteries and to better understand batteries and their functions in power system it is necessary to understand the characteristics and the technology of batteries. I mentioned various uses of BESS, but I focused on three most common problems, which are frequency regulation, voltage regulation and peak shaving. Then I introduced largest BESS manufacturers and their biggest projects
