Electrical energy storage in distribution network

U diplomskom radu su opisane osnove potrebe za pohranom elektriĉne energije te princip rada spremnika elektriĉne energije sa prednostima i nedostatcima. U diplomskom radu su opisane tehnologije koje se koriste za pohranu elektriĉne energije. A to su: reverzibilne hidroelektrane, spremnici sa komprimiranim fluidom, baterijski spremnici, spremnici koji koriste zamašnjak, te spremnici koji koriste superkondenzatore. Izvršena su mjerenja napona i struje punjenja i praţnjenja baterije te je opisan proces odreĊivanja veliĉine i lokacije spremnika elektriĉne energije.In this thesis are described basics need for electric energy storage, and principle of work energy storage with it advantages and disadvantages. In thesis also are described technology which are used for electric energy storage. Some of these are: pumped hydro, storage with compressed fluid, battery storage, storage with flywheel, and supercapacitor storage. There is made process of measurement voltage and current of charging and discharging battery. And also in thesis is described process of defining size and location of electric energy storage
