Abstract
U ovom radu definirani su pojmovi distribuirane proizvodnje (DG) i aktivnih kupaca. Funkcija cilja u ovom diplomskom radu je minimizacija gubitaka te su opisane metode i tehnike za minimizaciju gubitaka u distributivnoj mreži. Teorijski je objašnjeno kako fotonaponski sustavi mogu proizvoditi jalovu snagu pomoću izmjenjivača. U radu je analizirana jedna niskonaponska distributivna mreža s velikim brojem aktivnih kupaca. Niskonaponska distributivna mreža s tri radijalna izvoda modelirana je pomoću programa DIgSILENT PowerFactory. U programu su korišteni tokovi snaga, u kojima fotonaponski sustavi proizvode samo radnu snagu te je korišten modul optimalnih tokova snaga, pomoću kojega sam program određuje iznos jalove snage koju će proizvoditi fotonaponski sustavi, kako bi gubici bili što manji. Analizirani su tokovi snaga u slučaju kada fotonaponski sustavi nisu u funkciji. Također su analizirani tokovi snaga i optimalni tokovi snaga kada fotonaponski sustavi rade s 75% snage i 99,9% snage. Za sve scenarije prikazani su gubici radne i jalove snage, vrijednosti napona te su uspoređeni rezultati.
Abstract (english)
This paper defines the concepts of distributed generation (DG) and prosumers. The objective function in this thesis is to minimize losses, and methods and techniques for minimizing losses in the distribution network are described. It is theoretically explained how photovoltaic system can produce reactive power using inverters. The paper analyses a low voltage prosumer-rich distribution network. The low voltage distribution network with three radial terminals was modelled using the DIgSILENT PowerFactory program. The program uses power flows, in which photovoltaic system produce only active power, and uses the module of optimal power flows, with which the program itself determines the amount of reactive power that will be produced by photovoltaic system, to minimize losses. Power flows in the case of photovoltaic system are not in operation are analysed. Power flows and optimal power flows when photovoltaic system operate at 75% power and 99.9% power were also analysed. For all scenarios, active and reactive power losses, voltage values are presented, and the results are compared.
