Alternative models and concepts for financing renewable energy sources

U sklopu završnog rada prikazani su načini financiranja obnovljivih izvora energije u distribuiranim sustavima. Razvoj tih sustava omogućuje građanima da se aktivno uključe u izgradnju vlastitih mikroelektrana. Prikazani su primjeri alternativnih modela financiranja u Republici Hrvatskoj. Provedena je analiza i usporedba dva sustava. Model 1 energiju dobiva iz mreže i diesel agregata, dok model 2 energiju dobiva najviše iz OIE i baterijskih spremnika te ostatak iz mreže i agregata. Dobivene su cijene koje su analizirane kroz neto sadašnju vrijednost za period od 20 godina. Analiza je provedena uz alat za optimizaciju Gurobi i programski jezik Python.Various renewable energy sources financing methods in distributed systems are illustrated in this work. The development of these systems enables citizens to be actively involved in constructing micro powerplants for their own use. Alternative financing models in the Republic of Croatia are shown as well. Analysis and comparison were conducted between two systems. The first model gets its energy from power network and diesel aggregate, while the second model gets energy mainly from renewable energy sources and batteries and secondly from power network and diesel aggregate. Price values, that are analyzed trough NPV, are based on 20-year period. The analysis is conducted using Gorubi and Python programming language
