1. 11. 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.

3. 12. Power generation and stability of the Swedish electricity system 2045

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Samir Rawashdeh; [2023]
   Keywords : Duck curve; peak load; capacity factor; availability factor; stability; synthetic inertia; flexibility; ancillary services; solar power; wind power; hydropower; co-generation; heat generation; nuclear power; hydrogen production; electrolysis; fuel cells; V2G; PtG; P2G; P2G2P; ESS; PSH; SMR; NPP; HPP; FFR; Technology and Engineering;

   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. 13. Computing Equivalent hydropower models in Sweden using inflow clustering

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

   Author : Daniel Lilja; [2023]
   Keywords : Hydropower; Equivalent; Bilevel; Optimization; Clustering; Inflow; Sweden; Vattenkraft; Ekvivalent; Bilevel; Optimering; Klusteranalys; Inflöde; Sverige;

   Abstract : To simulate a hydropower system, one can use what is known as a Detailed model. However, due to the complexity of river systems, this is often a computationally heavy task. Equivalent models, which aim to reproduce the result of a Detailed model, are used to significantly reduce the computation time for these simulations. READ MORE

5. 14. Application and Optimization of an Energy Hub Concept for an Eco-Industrial Park Development Project : A Case Study at Tofte Industrial Park, Norway

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Støvne Eivind Myklebust; [2022]
   Keywords : ;

   Abstract : The concept of “eco-industrial parks” have been defined to facilitate circular and sustainable use of resources in industrial locations. The term encompasses industrial parks where there is significant focus on energy efficiency, residual heat utilization, industrial symbioses and renewable energy sources. READ MORE

6. 15. Stochastic Adaptive Robust Approach in the Optimal Bidding Behavior of a Virtual Power Plant in the Multi-Market Setup

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

   Author : Nina Manivong; [2022]
   Keywords : Robust optimization; stochastic programming; strategic offering; uncertainty; virtual power plant; hydro-power; wind; storage; Robust optimering; stokastisk programmering; strategiskt erbjudande; osäkerhet; virtuellt kraftverk; vattenkraft; vindkraft; lagring;

   Abstract : Hydropower in Sweden is a powerful and efficient source of energy due to its flexibility, usually used to balance the Swedish power system. With the transition of power system into more intermittent power sources, the role of hydro-power as producers will become more important. READ MORE
