Abstract

Primjenom računala optimiran je nelinearan autonoman fotonaponski sustav. U tom je cilju izvršeno modeliranje sastavnih komponenata, postavljen je model za simulaciju na računalu, te definiran algoritam optimiranja sustava. Također su definirani ulazni podaci i određen korak diskretizacije kao kompromis između kvalitete simulacije s jedne i trajanja proračuna s druge strane.
Odabrani su prikladni modeli za sve komponente : fotonaponsko polje, akumulatorsku bateriju, potrošač i kontrolni podsustav. Simulacijski model određuje tok energije unutar sustava u obliku vatsatnih i ampersatnih suma i predstavlja osnovu za optimiranje.
Postupkom se optimiranja utvrđuje optimalan kut nagiba i optimalna površina fotonaponskog polja, te optimalan kapacitet akumulatorske baterije, minimiziranjem funkcije cilja.

Abstract (english)

In order to optimize the work of a nonlinear autonomous photovoltaic system the computer aided methods were applied. For that purpose the modeling and the computational algorithm were performed. The input data and discretization step were defined as the compromis between the degree of simulation quality and duration of the computer program.
The suitable models for all structural components have been selected for: photovoltaic array, storage battery, load and control subsystem. The overall simulation model defining flow of energy through the system was the basis for the optimization process.
The optimum values for tilt angle, array area and battery capacity have been detemined by minimizing the objective function.
