1. Damping of sub-synchronous control interactions with a STATCOM : Wind farms & series compensated power lines
University essay from Uppsala universitet/Institutionen för elektroteknikAbstract : The power converter is one of the key components in power system applications such as high voltage direct current (HVDC) systems and the grid connection of intermittent sources such as wind and solar power. However, the increased penetration of converter-based generation introduces challenges, such as sub-synchronous interaction between the converter control system and the grid. READ MORE

2. Fabrication and Characterization of Quantum-well Field Effect Transistor
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : The project aims to optimize the design and fabrication of InGaAs quantum-well field-effect transistor (QW-FET) by investigating transfer and output characteristics of the QW-FET. This work found a lower source/drain contact resistance solution starting with fabricating micrometer-level gate length transistors. READ MORE

3. Investigating Particle Cracking in Single- and Polycrystalline Nickel-Rich Cathodes using In Situ Impedance Spectroscopy
University essay from Uppsala universitet/StrukturkemiAbstract : State-of-the-art Li-ion cathode materials are based on LiMO2 (M=Ni, Mn, Co) layered transition metal oxides (denoted NMC) with Ni-rich composition because of their high specific capacity. Yet, these materials suffer from poor capacity retention due to crack formation during de-/lithiation cycling. READ MORE

4. Open Source Model of the Nordic Power System for EU Project Spine
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Decision problems in operation and planning of power systems often rely on large-scale models and data sets. Lack of historical power flow data due to regulatory restrictions often limits researchers to study the system with aggregated network models. READ MORE

5. Machine Learning Enabled Nonlinear Phase Noise Mitigation for Coherent Optical Systems
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : In the current development of coherent optical communication systems, nonlinear noise is considered to be the ultimate bottleneck when extending the transmission length. In this report we suggest a nonparamter digital signal processing scheme to extend the transmission length of a fiber link. READ MORE
