1. The role of location of low inertia in power systems
University essay from Uppsala universitet/Institutionen för elektroteknikAbstract : The plans to reduce the energy-related greenhouse gas emissions stimulate the deployment of electronically interfaced renewable resources. The increased penetration of such intermittent sources together with phasing conventional power plants out and the installation of High Voltage Direct Current (HVDC) links for long-distance more efficient transmission, reduces the stored inertia in any electrical grid.

2. Evaluation of Power Oscillation Damping in the Nordic Grid Using HVDC
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : With a rapid transition towards renewable energy sources and increasing demand for electricity, we are facing major changes in the electricity grid. With increased congestion and reduction of inertia the grid is becoming more sensitive to rotor angle stability issues, such as the stability of interarea modes or power oscillation damping (POD).

3. Generation and Characterization of Intense Attosecond Pulses
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : Research on ultrafast dynamics in atoms and molecules requires short pulses. In order to resolve processes taking place on a femtosecond timescale sufficiently, these pulses require a duration on the attosecond time scale. READ MORE

4. Analysis of Hybrid Offshore Floating Wind and Marine Power
University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskapAbstract : Wind energy is a major part of renewable energy production. With fossil fuel depletion and climate change at the cusp, it is an absolute need to implement or evolve the current source or utilization of renewable energy. The wind has been dominating the onshore for many decades and offshore wind turbines are available at shallow depths. READ MORE

5. Optimization of liquid flow rate distribution in etching modules through numerical simulationsand experiments
University essay from KTH/Skolan för kemivetenskap (CHE)Abstract : The purpose of this study was to simulate the liquid flow rate distribution in the etching modules and find the optimal setup in order to achieve a distribution as homogenous as possible. The commercial software Matlab 2015a has been employed for all the numerical simulations. The optimization has been carried out varying several parameters, i.e. READ MORE
