Abstract

Obnovljivi izvori energije danas igraju ključnu ulogu u proizvodnji električne
energije. Proizvodnja iz sunčeve energije sve se više širi kroz industriju i privatni sektor. U
ovom radu dan je pregled najčešćih topologija istosmjernih pretvarača za povezivanje
fotonaponskog modula na spremnik energije te pregled izmjenjivača za spajanje modula na
izmjeničnu mrežu. Također je dan pregled MPPT algoritama koji se mogu implementirati u
takve sustave. U programskom alatu PLECS izrađen je model sustava u kojemu je
fotonaponski modul spojen na baterijski spremnik energije. Simulacijom je prikazan rad
sustava za različita ozračenja i temperature modula. Pomoću elektro-toplinskih modela
simulirani su gubici poluvodičkih sklopki.

Abstract (english)

Today, renewable energy sources have a key role in the production of electric
energy. Production from solar energy is more and more expanding through the industry and
private sector. An overview of power converters for battery storage systems and inverters
for grid-connected systems in photovoltaic applications is given in this paper. The most
common MPPT algorithms are also described. This thesis gives a detailed model of a
photovoltaic system in which the module is connected to the battery storage. The model is
made in PLECS software package. The simulation is carried out for different irradiation
and temperatures of a solar module. Thermo-electrical models of the switches were made
to simulate semiconductor losses.
