Valuation and management of generation flexibility of virtual power plants on the electricity market

V diplomskem delu smo se osredotočili na praktično uporabo virtualnih elektrarn na razvitih zahodnih trgih električne energije z vidika dobavitelja in trgovca električne energije. Predstavili smo razvoj trga električne energije na evropskem prostoru, trenutno stanje ter izzive, s katerimi se soočajo udeleženci trga, s čimer potrjujem potrebo po uvajanju virtualnih elektrarn. Predstavili smo pojem virtualne elektrarne ter različne primere uporabe virtualnih elektrarn. Prikazali smo metodologijo vrednotenja prilagodljivosti proizvodnje virtualnih elektrarn namenjene izkoriščanju nihajnosti cen na trgu električne energije za dan v naprej. Teorijo vrednotenja prilagodljivosti proizvodnje virtualnih elektrarn smo podprli z prikazom rezultata vrednotenja na praktičnem primeru virtualne elektrarne na nemškem trgu električne energije. Predstavili smo pomen ter metodo ščitenja porftelja sestavljenega iz prilagodljive proizvodnje virtualne elektrarne. Razlago pomena ščitenja smo podpri z rezultati v praktičnem primeru. Na koncu pa smo prikazali še izzive, s katerimi se sooča lastnik prilagodljivosti proizvodnje med samim obdobjem dobave električne energije.In this thesis, we have focused on the practical application of virtual power plants in developed Western markets from the perspective of electricity supplier and electricity trading company. We have presented the electricity market in Europe, its development and challenges faced by market participants, thus confirming the need for the introduction of virtual power plants. We have presented the concept of virtual power plants and illustrated various examples for uses of virtual power plants. We have shown the valuation methodology of flexible production from virtual power plants designed for exploiting of price volatility in electricity market. We have illustrated the valuation theory of production flexibility from virtual power plant with a realistic example and have presented the outcome of the evaluation on practical example of virtual power plant in German electricity market. We have introduced the importance of hedging portfolio with flexible production from virtual power plants and presented different methodologies of hedging. We have supported hedging strategy with practical example. At the end we have shown the challenges the owners of flexible production are facing during the delivery period
