1. 6. Designing an Electric Road System

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : David Pålsson; Samuel Henley; [2023]
   Keywords : ERS; Electric Road System; Power Demand; Energy Storage; Peak Shaving; Emergency Backup; Elväg E20; Hallsberg; Örebro; Technology and Engineering;

   Abstract : Electric road systems (ERS) provide electric power to vehicles en route (dynamic charging) and can reduce the need for onboard battery capacity. This thesis sets out to examine the power demand of an ERS and the integration of energy storage in its power supply for grid load alleviation and backup power. READ MORE

3. 7. Optimal Control of An Energy Storage System Providing Fast Charging and Ancillary Services

   University essay from KTH/Optimeringslära och systemteori

   Author : Max Völcker; Hugo Rolff; [2023]
   Keywords : Optimal Control; Model Predictive Control; Dynamic Programming; State-Space Representation; Monte Carlo Simulation; Frequency Regulation; Fast Charging; Energy Storage Systems; Net Present Value; Optimal styrteori; Modell-prediktiv reglering; Dynamisk programmering; Frekvensreglering; Snabbladdning; Energilager; Nuvärde;

   Abstract : In this thesis, we explore the potential of financing a fast charging system with energy storage by delivering ancillary services from the energy storage in an optimal way. Specifically, a system delivering frequency regulation services FCR-D Up and FCR-D Down in combination with energy arbitrage trading is considered. READ MORE

4. 8. 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. 9. Klimatpåverkan och energianvändning vid tillämpning av bio-CCS och bio-CCU från biogasanläggningar

   University essay from SLU/Dept. of Energy and Technology

   Author : Emelie Wallman; [2022]
   Keywords : livscykelanalys; koldioxid; biometan; power to gas; biologisk metanisering; katalytisk metanisering; elektrolys;

   Abstract : To mitigate the human-induced climate change, Sweden has adopted a climate policy framework that states a net-zero emissions of greenhouse gases by the year of 2045 and thereafter negative emissions. To achieve this goal extensive emission mitigation alongside supplementary measures are required. READ MORE

6. 10. 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
