2. Evaluation of OPAL-RT Simulator through Simulation of Microgrid with High Penetration of DER
University essay from Uppsala universitet/ElektricitetsläraAbstract : This thesis was written in collaboration with the department of electrical engineering at Uppsala University. It evaluates and tests the potentials and limitations of using the OPAL-RT simulator as a tool for designing and developing control strategies used in microgrids with a high penetration of distributed energy resources.

3. Development and Analysis of Small Signal DQ-Frame Model for Low Frequency Stability of Train Converters
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : In order to meet the increasing demand for sustainable transportation, trains need to run with tighter schedules, more departures and more trains in depot. Multiple trains in depot has been linked to low frequency instability at many locations around the world. READ MORE

4. Analysis of high-voltage low-current DC/DC converters for electrohydrodynamic pumps
University essay from Uppsala universitet/Institutionen för elektroteknikAbstract : Moving parts cause vibrations and tend to wear out. In applications where maintenance is complicated, solutions without moving parts are therefore advantageous. Electrohydrodynamic pumps are such a solution. Instead of mechanical propulsion, they use strong electric fields to induce movement in a dielectric cooling liquid. READ MORE

5. Development of an embedded system platform for signal analysis and processing
University essay from Uppsala universitet/Signaler och systemAbstract : Information is often stored and transmitted through electrical signals. This information may need refinement, which may be done by processing and altering the electrical signals, in which it is transmitted. When refining a signal, a frequency selective filter is often used. It can be implemented through digital signal processing (DSP). READ MORE
