1. 1. 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

3. 2. NH Planetary-Scale Circulation in Troposphere and Stratosphere: A Spectral and Dynamical Perspective

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Michael Konrad Schutte; [2023]
   Keywords : jet stream; Rossby waves; polar vortex; spectral analysis; dynamic systems theory; sudden stratospheric warmings; strong polar vortex events; jetström; Rossbyvågor; polär virvel; spektralanalys; dynamisk systemteori; plötsliga stratosfäriska uppvärmingar; starka polvortexhändelser;

   Abstract : Dynamic Systems Theory (DST) and spectral analysis are employed to study the tropospheric jet stream and the stratospheric polar vortex. The objective is to investigate the relationship between Rossby wave activity and inverse persistence and dimensionality of geopotential height at 250 hPa and 10 hPa, as these two dynamical indicators are expected to show a characteristic behavior of Rossby wave harmonics.

4. 3. Longitudinal Flight Mechanics of Paraglider Systems

   University essay from KTH/Flygdynamik

   Author : Rene Falquier; [2019]
   Keywords : ;

   Abstract : This project outlines a cost-effective numerical simulation method for the analysis of the longitudinal mechanics of paraglider systems. It is built on static stability methods for the analyses of low subsonic aircraft, non-linear lifting line methods for aerodynamic parameterization, and frequency domain analysis methods derived from system theory.

5. 4. Optimal Energy Management for Parallel Hybrid Electric Vehicles using Dynamic Programming

   University essay from KTH/Optimeringslära och systemteori

   Author : Nikita Tagner; [2017]
   Keywords : ;

   Abstract : In this thesis, two optimal control problems for the control of hybrid electric vehicles are formulated. The first is general formulation where both velocity and state of charge can vary. The second is a formulation where the velocity is prespecified and therefore only the state of charge can vary.
