Abstract [en]

Small scale hydropower is an often overlooked, yet important, part ofSweden’s current and future sustainable energy system. In this study, the benefits ofcoordinating smallscale hydropower generation was evaluated using the modelingsoftware Spine. Two models were created representing the same river system but withdifferent planning strategies. A successive greedy model simulated the current situationfor a lot of smallscale hydropower systems, where individual power plant ownersoptimize their production without regard to downstream plants. A coordinated onesimulated a situation where they all cooperate in order to optimize the entire system’srevenue. Different scenarios with different combinations of parameters were simulatedand evaluated. The results were that the coordinated model generated about 0–2% moreelectricity and revenue than the successive greedy model. This is lower than what aprevious study has found, which indicated it might be closer to 10%.

Abstract [sv]

Småskalig vattenkraft är en ofta förbisedd, men likväl viktig, del avSveriges nuvarande och framtida hållbara energisystem. I denna studie utvärderadesfördelarna med att koordinera småskalig vattenkraftsproduktion med hjälp avmodelleringsmjukvaran Spine. Två modeller skapades som representerar samma älvmen med olika planeringsstrategier. En successivt girig modell simulerade nuläget förmånga småskaliga vattenkraftsystem, där enskilda kraftverksägare optimerar sinproduktion utan hänsyn till nedströms liggande anläggningar. En koordinerad modellsimulerade en situation där de alla samarbetar för att optimera hela systemets intäkter.Olika scenarier simulerades där systemets parametrar varierades och utvärderades.Resultaten blev att den koordinerade modellen genererade ungefär 0–2% merelektricitet och intäkter än den succesivt giriga modellen. Detta är lägre än vad entidigare studie funnit, där resultaten var närmare 10%.
