1. 1. Towards a Stochastic Operation of Switzerland’s Power Grid

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

   Author : Alban Maury; [2023]
   Keywords : Monte-Carlo simulations; probabilistic forecasting; copula theory; power flow analysis; Monte Carlo-simuleringar; probabilistiska prognoser; kopulateori; analys av energiflöden;

   Abstract : As Europe’s power production becomes increasingly reliant on intermittent renewable energy sources, uncertainties are likely to arise in power generation plans. Similarly, with the growing prevalence of electric vehicles, electric demand is also becoming more uncertain. READ MORE

3. 2. Network reconfiguration for renewable generation maximization

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Gabriel Malmer; Lovisa Thorin; [2023]
   Keywords : distributed generation; hosting capacity; network reconfiguration; optimal power flow; power distribution; optimization; mixed-integer programming; Technology and Engineering;

   Abstract : Increasing the amount of renewable generation in distribution networks is a fundamental part of the energy transition. Multiple methods exist to increase the hosting capacity in a grid, to allow larger injections of generation and more efficiently utilize existing infrastructure before operational limits are breached.

4. 3. Optimal Dispatch of Green Hydrogen Production

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

   Author : Nicolas Garcia Vargas; [2023]
   Keywords : Green Hydrogen; Dispatch Optimization; Multi-Energy System; Energy Storage; LCOH.; Grön vätgas; Uppdrags Optimering; Multi-Energi System; Energilagring; LCOH.;

   Abstract : This project proposes a hybrid system for hydrogen production, which includes a connection to the grid, a source of renewable energies, namely photovoltaic (PV), a Battery Energy Storage System (BESS), and a PEM (Proton Exchange Membrane) electrolyzer modelled from commercial technologies available. A dispatch optimization algorithm will evaluate the price of the energy inputs and the power available from the solar PV system and will decide the operation on an hourly basis to maximize net profit in a year timeframe.

5. 4. Fault current injection from Inverter Based Generation in the distribution grid : A case study of distribution grid on the Swedish island of Gotland

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Farsad Mansori; [2022]
   Keywords : Distribution generator; Inverter-Based Distributed Generation; Inverter Based Generation; DFIG; PSCAD; Distribution grid; Overcurrent protection;

   Abstract : This work proposes recommendations for new guidelines for fault current injection on a distribution grid. These guidelines will help improve the transition towards renewable electrical energy generation. READ MORE

6. 5. Application of harmonic injection method to analyse Sub-Synchronous Control Interactions (SSCI)

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

   Author : Linus Eriksson; [2022]
   Keywords : Sub-synchronous control interaction SSCI ; damping of SSCI; DFIG; PSCAD; Power Oscillation Damper POD ; Harmonic Injection; Subsynkrona kontrollinteraktioner SSCI ; dämpning av SSCI; DFIG; PSCAD; Dämptillsats POD ; Harmonisk Injection;

   Abstract : Wind farms are commonly connected to the main grid through compensated lines which increases the power transfer capability of the line. Double Fed Induction Generator (DFIG) wind turbines in connection to compensated lines can experience Sub-Synchronous Control Interaction (SSCI) which can bring system quantities above allowed levels.
