Abstract

Napredak tehnologije, kao i potreba za smanjenjem onečišćenja okoliša, natjerali su znanstvenike da počnu tražiti alternative dosad konvencionalnim načinima opskrbljivanja energijom. Kao odgovor na pitanje onečišćenja, ali i potrebe za kvalitetnijom električnom energijom javile su se istosmjerne mikromreže. U prilog njima ide i činjenica da se velik broj uređaja kako u kućanstvu, tako i u industriji, napaja istosmjernom strujom. Istosmjerna mikromreža sastoji se od distribuirane proizvodnje (malog vjetroagregata, fotonaponskih ćelija) te spremnika energije koji služi kao rezerva (baterijskog podsustava). Može biti priključena na vanjsku mrežu, ali i raditi u otočnom radu.

Abstract (english)

Technology advances, as well as need to reduce environment pollution, have made scientists to start searching for alternatives to conventional energy production. As answer to pollution, but also to a need for high quality electrical energy, there is created concept called DC microgrids. Their advantage is that many loads in our homes, as well as in industries work on DC current. DC microgrid consist of distributed generation (DG) such as photovoltaic cells (PV) and small wind turbine, energy storage systems (ESS) such as batteries and supercapacitors and they serve as reserve if production of distribute energy sources is too small. DC microgrid can work connected to a conventional AC grid, or in islanded mode.
