1. Pumped-Storage Hydroelectricity for a Sustainable Electricity Transition
University essay from KTH/Numerisk analys, NAAbstract : 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

2. The influence of short-term forecast errors in energy storage sizing decisions
University essay from KTH/Skolan för industriell teknik och management (ITM)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

3. Alternative Energy Storage Solutions and Future Scenarios of the Austerland Energy System
University essay from KTH/Skolan för industriell teknik och management (ITM)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

4. Modeling of a stand-alone liquid air energy storage
University essay from Lunds universitet/Institutionen för energivetenskaperAbstract : 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. READ MORE

5. Increasing Photovoltaic penetration rate on isolated grid using storage, overbuilding and curtailment: Case study of the Reunion Island
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : In the global context of GHG emissions reduction, insular isolated grids which are the most vulnerable systems in terms of fossil fuel dependency have to conduct their energy transition. Conventional units using fossil fuels are well adapted to those systems because they are dispatchable, reliable and flexible, so they can easily respond to grid requirements. READ MORE
