Energy storage systems in smart grids

U ovom se završnom radu detaljno opisuju sustavi pohrane električne energije i njihov princip rada. Također se opisuju napredne mreže te njihova implementacija, model, značajke, prednosti i nedostatci. Analiza i simulacija je provedena u programu DIgSILENT PowerFactory a cilj je bio što bolje prikazati utjecaj baterija i gorivih ćelija na mrežu. Na temelju rezultata simulacije donesen je zaključak.This paper describes in detail the energy storage systems and their principle of operation. It also describes smart grids and their implementation, model, features, advantages and disadvantages. The analysis and simulation was performed in the DIgSILENT PowerFactory program and the goal was to show the impact of batteries and fuel cells on the grid. Based on the simulation results, a conclusion was reached
