  1. 6. Dynamic Control, Modeling and Sizing of Hybrid Power Plants : Investigating the optimum usage of energy storage for Fortum’s hydropower

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Klas Lindgren; [2023]
    Keywords : Hydropower Plants; Energy Storage Systems; Hybrid Units; Frequency Regulation; Modeling; XGBoost Regression; Vattenkraftverk; Energilagringsystem; Hybridkraftverk; Frekvensreglering; Modellering; XGBoost Regression;

    Abstract : The rapidly evolving Nordic Power System demands enhanced flexibility and robustness in electricity production. The traditional role of hydropower plants in regulating the grid frequency has been challenged by new criteria for dynamic stability, which some units struggle to meet due to their relatively poor dynamic performance.

    Abstract : På grund av energiomställningen, Sveriges mål om att ha en fossilfri elproduktion 2040 samt målet om nettonollutsläpp av växthusgaser 2045 förväntas en omfattande utbyggnad av förnybara energikällor ske. I denna rapport har därför elbehovet, potentialen för elproduktion, möjliga framtida systemproblem samt lösningar undersökts. READ MORE

  4. 8. Optimal Control of An Energy Storage System Providing Fast Charging and Ancillary Services

    University essay from KTH/Optimeringslära och systemteori

    Author : Max Völcker; Hugo Rolff; [2023]
    Keywords : Optimal Control; Model Predictive Control; Dynamic Programming; State-Space Representation; Monte Carlo Simulation; Frequency Regulation; Fast Charging; Energy Storage Systems; Net Present Value; Optimal styrteori; Modell-prediktiv reglering; Dynamisk programmering; Frekvensreglering; Snabbladdning; Energilager; Nuvärde;

    Abstract : In this thesis, we explore the potential of financing a fast charging system with energy storage by delivering ancillary services from the energy storage in an optimal way. Specifically, a system delivering frequency regulation services FCR-D Up and FCR-D Down in combination with energy arbitrage trading is considered. READ MORE

  5. 9. Implementation of battery energy storage systems in the Swedish electrical infrastructure

    University essay from KTH/Kemiteknik

    Author : Gustav Arnberg; [2022]
    Keywords : Battery energy storage systems; BESS; Li-ion batteries; Frequency regulation; Business case; Implementation of battery energy storage systems; Swedish electrical infrastructure; BESS; Li-jon batterier; Frekvensreglering; Affärsfall; Implementering av batterilagringssystem; Svensk elinfrastruktur;

    Abstract : Detta examensarbete utreder den tekniska och ekonomiska passbarheten av batterilagringssystem (BESS) inom den svenska el infrastrukturen. Syftet är att konstruera tre olika affärsfall för att representera den tekniska och den ekonomiska passbarheten av BESS inom den svenska el infrastrukturen, specifikt med uppkoppling mot distributionsnätverket på den regionala nivån, 6 kilovolt till 132 kilovolt (kV).
