1. 1. Parallel Operation of Grid-Forming Power Inverters

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

   Author : Alessia Camboni; [2023]
   Keywords : ;

   Abstract : The use of renewable energy sources has been increasing during the last few years, both to obtain a less impacting energy production, and because of the limited fossil resources. Renewable sources are connected to the grid using inverters, which can be controlled in two main modes, grid-following, and grid-forming. READ MORE

3. 2. Evaluation of key performance indices for frequency quality : A method for evaluating frequency stability in the Nordic power system

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

   Author : Sophia Larbi Engelbrektsson; [2023]
   Keywords : Ancillary Services; Kinetic Energy; Frequency Dependent Load; Frequency Stability; Frequency Quality; KPI; Nordic Power System; Frekvensberoende Last; Frekvenskvalité; Frekvensstabilitet; Kinetisk Energi; Nordiska Elsystemet; Nyckeltal; Stödtjänster;

   Abstract : The Nordic power system is in a changing phase, with more power electronic interfaced connections, and HVDC connections to other synchronous areas, which impacts the frequency quality. This is a challenge for the transmission system operator of Sweden, Svenska Kraftnät, who, with the other Nordic transmission system operators, is responsible for the physical balancing of the Nordic power system.

4. 3. Analysing the Effect of Working Memory Training on Brain Networks Using MEG and Neuroimaging

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Jeanie Dawnbringer; [2022]
   Keywords : Brain networks; Magnetoencephalography; Working memory; Plasticity; Neuroimaging;

   Abstract : Introduction: The brain can change its structure and functionality as a result ofexternal factors. The working memory (WM) of the brain is where informationcan be held and manipulated during a short period of time, with the purpose ofachieving higher cognitive functions such as reasoning and learning.

   Keywords : Interior permanent magnet synchronous motor; Continuous control set-Model predictive control; Linear quadratic regulator; Quadratic programming; Interior permanent magnet synchronous motor; Continuous control set-Model predictive control; Linear quadratic regulator; Quadratic programming;

   Abstract : The thesis provides design methods for developing Continuous Control SetModel Predictive Control and Linear Quadratic Regulator for Interior mounted Permanent Magnet Synchronous Motor drive. The software for these controllers are implemented in the prototype motor at China Euro Vehicle Technology (CEVT) to estimate the computation time. READ MORE

6. 5. Future Nordic Grid Frequency Quality : A quantitative simulation study of current and potential frequency control methods with emphasis on synthetic inertia

   University essay from Uppsala universitet/Elektricitetslära

   Author : Emil Arvidsson; [2021]
   Keywords : grid frequency; synthetic inertia; frequency control; power grid; hydro power;

   Abstract : The power grid faces stability problems due to loss of inertia. The ancillary services balancing the system must be improved to maintain stability. READ MORE
