Supply of electric energy from renewable sources in a region

Namen diplomskega dela je analiza potenciala pokrivanja električne energije z obnovljivimi viri na Gorenjskem. V uvodu so opisani načini pridobivanja električne energije iz Sonca, vetra in biomase ter karakteristike elektrarn na obnovljive vire energije. Preko analize dnevne, tedenske in letne porabe električne energije v Sloveniji, je s skaliranjem ocenjena poraba za Gorenjsko. Okvirna zmožnost pridobivanja električne energije iz obnovljivih virov je izračunana na podlagi povprečenja vremenskih podatkov treh gorenjskih krajev ter izkoristkov vetrne elektrarne (Enercon E-70 E4 2.300), komercialnega sončnega modula (AU380-30-MH) in elektrarne na biomaso. Rezultati so nato primerjani z ocenjeno porabo gorenjske regije. Ugotovimo, da pokrivanje celotne porabe električne energije zgolj z eno vrsto elektrarn ni izvedljivo zaradi prostorskih ali okoljskih dejavnikov in izzivov pri shranjevanju energije. Zaključimo, da bi se morali v gorenjski regiji bolj kot na vetrno in sončno energijo zanašati na energijo iz biomase, vendar je pokrivanje porabe samo z obnovljivimi viri trenutno neizvedljivo.The aim of the thesis is to analyse the potential of electricity generation from renewable energy sources in Gorenjska region. The introduction describes how electric energy can be generated from solar, wind and biomass. The characteristics of renewable energy plants are given. Through the analysis of daily, weekly and annual electric energy consumption in Slovenia, the consumption for Gorenjska is estimated by scaling. The indicative renewable electric energy generation capacity is calculated by averaging the weather data of the three Gorenjska sites and the efficiencies of the wind farm (Enercon E-70 E4 2.300), the commercial solar module (Enercon E-70 E4 2.300) and the biomass power plant. The results are then compared with the estimated consumption of the Gorenjska region. We find out that it is not feasible to cover all electric energy consumption with just one type of power plant due to spatial or environmental factors and energy storage challenges. We conclude that the Gorenjska region should rely on biomass energy rather than wind and solar energy, but at the moment it is not feasible to cover the consumption by renewable sources only
