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. Study on feasibility of small-scale pumped hydro storage- A case study in Sweden

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Prashant Niroula; [2023]
   Keywords : energy storage; pumped hydropower; electricity market; investment; new technologies; feasibility; Technology and Engineering;

   Abstract : The European union has been aggressively pushing forward with policies favoring renewable sources of energy. As a result, the share of intermittent renewables in the European power grid is rising and is expected to grow even more in the coming decade. The Swedish energy agency also forecast huge growth in wind power. READ MORE

5. 14. The effects of renewable energy generation on electricity prices

   University essay from SLU/Dept. of Economics

   Author : Sandra Ericsson; [2023]
   Keywords : Renewable energy sources; electricity prices;

   Abstract : This thesis investigates the effect of different electricity generation sources on the price of electricity in Denmark, Finland, Norway, and Sweden. This is done by using panel data regressions with annual data for the period between 2004 and 2021. READ MORE

6. 15. 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
