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

   University essay from Lunds universitet/Industriell elektroteknik och automation

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

   Abstract : 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. Pumped-Storage Hydroelectricity for a Sustainable Electricity Transition

   University essay from KTH/Numerisk analys, NA

   Author : Teodor Elmfeldt; [2023]
   Keywords : Pumped-storage hydroelectricity; Electric grid; Computational Mathematics; Juktan Power Station; Applied mathematics; Power system; Sustainability; Pumpkraft; Elnät; Beräkningsmatematik; Juktan Kraftverk; Tillämpad mate- matik; Elkraftteknik; Hållbarhet;

   Abstract : This master thesis explores the application of Pumped-Storage Hydroelectricity (PSH) within an electricity market characterised by a substantial share of renewable and intermittent electricity production. The purpose of PSH is to enhance the alignment of supply with demand by storing energy at electricity surplus and releasing it during shortage. READ MORE

4. 3. The influence of short-term forecast errors in energy storage sizing decisions

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

   Author : Adrian Bagger Toräng; Viktor Rönnblom; [2022]
   Keywords : Energy storage system; Pumped hydro energy storage; Electricity price forecast; Forecast error; Sizing; Robust decision making; Energilagringssystem; Pumpkraftverk; Elprisprognos; Prognosfel; Dimensionering; Robust beslutstagande;

   Abstract : Pumped hydro energy storages commonly plan their operations on short-term forecasts of the upcoming electricity prices, meaning that errors in these forecasts would entail suboptimal operations of the energy storage. Despite the high investment costs of pumped hydro energy storages, few studies take a holistic approach to the uncertainties involved in such investment decisions. READ MORE

5. 4. Short-term planning and operational profitability of multi-ESS hybrid wind farms

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

   Author : Javier Ortega Paredes; [2022]
   Keywords : Energy storage systems; day-ahead market; wind power; stochastic short-term planning problem; hybrid wind farm; Energilagringssystem; day-ahead-marknad; vindkraft; stokastiskt kortsiktigt planeringsproblem; hybridvindkraftverk.;

   Abstract : The unpredictability and variability of wind power generation can pose an economical risk to the wind power producer when participating in the day-ahead market and delivering the committed generation. These risks come from the creation of imbalances due to a mismatch between the sold and real generation fed to the grid. READ MORE

6. 5. Alternative Energy Storage Solutions and Future Scenarios of the Austerland Energy System

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

   Author : Jennie Lindblom; [2022]
   Keywords : Gotland; Östergarnslandet; Polygeneration system; Homer Pro; Solar PV; Wind power; Energy storage; Battery; Hydrogen; Flywheel; Redox Flow battery; Pumped Hydro; Sustainable development.; Gotland; Östergarnslandet; Poly-genererings system; Homer Pro; Solceller; Vindkraft; Energilagring; Batterier; Vätgas; Svänghjul; Redox Flödesbatteri; Pumpkraftverket; Hållbar utveckling.;

   Abstract : The project Austerland Energi at the eastern tip of the island of Gotland called Östergarnslandet was started as a response to the larger project Omställning Gotland funded by the Swedish government as an effort for a pilot project to convert to renewable energy to reach zero CO2-emissions for the country in 2045. The current plan for the Austerland energy system is a solar PV and wind production base with energy storage in the form of batteries and hydrogen which also can be used as vehicle fuel. READ MORE
