1. 1. Unlocking the Potential of Solar-Hydro Hybrid Solutions: Feasibility and Economic Analysis

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

   Författare :Måns Rosberg; [2023]
   Nyckelord :Hydropower; Solarpower; Hybrid power production; Solar-hydro hybrid power; Reservoir storage; Energy storage; Pumped hydro power; Floating PV; PV; Photovoltaics; Technology and Engineering;

   Sammanfattning : Hybrid solutions that combine multiple renewable energy sources, such as solar power and hydro power, are gaining popularity as a means of meeting the growing energy demands while minimising environmental impacts, but also as an opportunity of connecting solar power plants to the grid in areas where this might not be possible unless large investments are made. This master thesis aims to evaluate the feasibility and economic viability of integrating solar panels with an existing grid connection point at a hydro power plant, along with the introduction of an energy storage solution using a hydro power plant reservoir.

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

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

   Sammanfattning : 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.

4. 3. Optimization of Kaplan turbines for frequency regulation in hybrid hydropower plants

   Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

   Författare :Nayan Narkhede; [2022]
   Nyckelord :Kaplan; Kaplan turbines; frequency regulation; hybrid hydropower plants; wear and tear; guide vanes; runner blades;

   Sammanfattning : The increasing penetration of variable renewable energy sources in the Nordic Power System is causing frequency quality degradation and has increased the importance of primary frequency control provided by hydropower plants. Hydropower is the world’s largest renewable energy source.

5. 4. Tribological Performance of Hygrothermally Aged UHMWPE Hybrid Composites

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Luca Palmeira Belotti; [2018]
   Nyckelord :UHMWPE; aging; polymers; tribology;

   Sammanfattning : Stricter environmental regulations and trend of decreasing cost and increasing operational efficiency are the driving forces for the improvement of the tribological performance in many different industries. For example, in the case of hydropower plants, there has been increasing research carried out to achieve oil-free stations, which would substitute the oil-based lubricants with environmentally accepted lubricants or water.
