Abstract

U vremenima kada konvencionalne vjetroelektrane preuzimaju sve veću ulogu u proizvodnji električne energije u svijetu, pojavila se relativno nova tehnologija koja iskorištava visinske vjetrove. Ta tehnologija je još u razvoju, ali čeka ju svjetla budućnost zbog toga što ima mnogo prednosti i mjesta za napredak. U ovom radu prikazati će se postupak modeliranja jednog elektro-energetskog sustava koji sadrži jedinice za proizvodnju energije iz visinskih vjetrova. Simulacije će se raditi u EnergyPLAN programu. Analizirat će se isplativost takvog sustava te u kojoj mjeri na nju utječu različiti parametri. Nakon odabira četiri najbolja scenarija u pogledu ukupnih troškova, sustav će se provesti u proračun isplativosti putem IRR i LCOE funkcija. Zatim će se provesti analiza osjetljivosti gdje će se ispitivati kako se sustav ponaša ukoliko se mijenja jedna varijabla u proračunu. Provedene analize pokazale su kako je četvrti scenarij najisplativiji koji je imao 750MW fotonaponskih modula, 1000MW visinskih vjetroelektrana, 50GWh spremnika električne energije te 100MW dopuštenog uvoza i izvoza električne energije. Time se dokazalo da će uvoz i izvoz električne energije te pohrana električne energije imati veliku ulogu u bliskoj budućnosti u pogledu iskorištenja energije visinskih vjetrova i energije općenito te daljnji razvitak pohrane i distribucije električne energije.

Abstract (english)

In the time when conventional wind power plants take over greater part in electrical energy production int he world, there is relatively new techology which exploits high altitude wind energy. The technology is still developing, but it has a bright future while it has many advantages and enough room for improvements. This paper will show the modelling process of a power system which contain units for power production from high altitude winds. Simulations will be conducted in EnergyPLAN model. The profitability of power system will be analyzed and in in what measure will different parameters affect its profitability. After top four cases are selected in terms of overall costs, system will be carry out through calculation with IRR and LCOE functions. Then the sensitivity analysis will be carried out where the system will be tested how it will react if one variable in calculation is changed. The analyses showed that the fourth case is the most profitable one. It had 750 MW of photovoltaic modules, 1000MW HAWE units, 50GWh electrical energy storage and 100MW of electricity import and export capacity. It proved that electrical energy import and export and electrical energy storage will have a major role in near future in terms of high altitude wind energy exploitation and energy in general as much as in further development of electrical energy storage and its import and export.
