2. 1. Protection for Multiterminal HVDC Grids - A Digital Contribution

   Author : Ilka Jahn; Staffan Norrga; Hans-Peter Nee; Dirk Westermann; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVDC transmission; power system protection; IED; real-time systems; test bench; field programmable gate array; open-source hardware; open-source software; power engineering education; Electrical Engineering; Elektro- och systemteknik;

   Abstract : The aim of this thesis is to (1) enhance understanding of mechanisms that are important for the protection of high-voltage direct-current (HVDC) grids, and (2) suggest possible technical solutions. To that end, digital technologies were used both in simulation, as well as in a laboratory environment. READ MORE

4. 2. Experiments in indirect fault injection with open source and industrial software

   Author : Carl Cederberg; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

   Abstract : Software fault injection is a technique in which faults are injected into a program and the response of the program is observed. Fault injection can be used to measure the robustness of the program as well as to find faults in the program, and indirectly contributes to increased robustness. READ MORE

5. 3. NFV Service Chains at the Speed of the Underlying Commodity Hardware

   Abstract : Link speeds in networks will in the near-future reach and exceed 100 Gbps. While available specialized hardware can accommodate these speeds, modern networks have adopted a new networking paradigm, also known as Network Functions Virtualization (NFV), that replaces expensive specialized hardware with open-source software running on commodity hardware.

6. 4. Synchrophasor Applications and their Vulnerability to Time Synchronization Impairment

   Author : Muhammad Shoaib Almas; Luigi Vanfretti; Mario Paolone; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hardware-in-the-loop; phasor measurement units; real-time simulation; time synchronization; wide-area monitoring protection and control.; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Recent years have seen the significance of utilizing time-synchronized, high resolution measurements from phasor measurement units (PMUs) to develop and implement wide-area monitoring, protection and control (WAMPAC) systems. WAMPAC systems aim to provide holistic view of the power system and enable detection and control of certain power system phenomena to enhance reliability and integrity of the grid. READ MORE

7. 5. Facilitating Feature-Oriented Quality Assurance in Low-Maturity Variant-rich Systems

   Author : Mukelabai Mukelabai; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Variant-Rich Systems; Cloned Projects; Quality Assurance; Feature Location; Test Case Reuse; Recommender System;

   Abstract : Context: Many software systems exist in several variants customized for specific stakeholder requirements, such as different market segments or hardware constraints. This customization introduces a high level of complexity that renders traditional single-system quality assurance techniques inapplicable, since they need to consider variations and constraints between a system’s features—a.
