6. The influence of short-term forecast errors in energy storage sizing decisions
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : 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. LÄS MER
7. Short-term planning and operational profitability of multi-ESS hybrid wind farms
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : 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. LÄS MER
8. Alternative Energy Storage Solutions and Future Scenarios of the Austerland Energy System
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : 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. LÄS MER
9. Energilagring med pumpkraft i gruvor : En utredning av potentialen för långtidslagring i Sveriges energisystem
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : This thesis is divided in two sections. The first part consists of an interview study with 10 participants to investigate how the industry views the demand for energy storage and how it may develop in the future. Although some views differed, the study showed that a great responsibility lies on the existing hydropower. LÄS MER
10. Evaluation of available electricity storage technologies and the possible economic gain for Växjö Energi
Master-uppsats, KTH/Kraft- och värmeteknologiSammanfattning : As the renewable energy sources are finding more place in the energy generation technologies,the Swedish energy market is also undergoing transformations. Renewable energy sources inthe energy generation system brings more volatility and price fluctuations which can mean challenges and opportunities. LÄS MER
