1. Grundvattenpåverkan från pumpkraft - En fallstudie vid Stärnö Stenbrott
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)Sammanfattning : Pumpkraft är en energilagringsteknik där elektrisk energi omvandlas till lägesenergi i syfte att kunna omvandla tillbaka lägesenergin till elektrisk energi i ett framtida skede. Detta sker genom att vatten pumpas från ett lågt beläget vattenmagasin till ett högre beläget vattenmagasin. LÄS MER
2. Pumped-Storage Hydroelectricity for a Sustainable Electricity Transition
Master-uppsats, KTH/Numerisk analys, NASammanfattning : 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. LÄS MER
3. 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
4. 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
5. Modeling of a stand-alone liquid air energy storage
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : The aim of this project was to create a model of the stand-alone LAES for use in future work at Siemens Industrial Turbomachinery (SIT). The model was created in IPSEpro with components developed from the software's standard library of power plant components. Required fluid properties were obtained from the Refprop DLL. LÄS MER
