  2. 11. Analyzing Non-Functional Capabilities of ICT Infrastructures Supporting Power System Wide Area Monitoring and Control

    Author : Moustafa Chenine; Lars Nordström; Nouredine Hadjsaid; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power System Communication; Wide Area Monitoring and Control systems; Phasor Measurements Units; Power System Communication; SCADA systems.;

    Abstract : The strain on modern electrical power systems has led to an ever-increasing utilization of new information and communication technologies (ICT) to improve their efficiency and reliability. Wide area monitoring and control (WAMC) systems offer many opportunities to improve the real-time situational awareness in the power system. READ MORE

  4. 12. Voltage Dip (Sag) Estimation in Power Systems based on Stochastic Assessment and Optimal Monitoring

    Author : Gabriel Olguin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; power quality; symmetr?cal components; stochastic methods; impedance matrix; voltage dips; integer optimisation; power systems; short-circuit faults; voltage sags;

    Abstract : This dissertation deals with the statistical characterization of the performance of power systems in terms of voltage dips (sags). It presents a method named voltage dip estimation that extends monitoring results to buses not being monitored. READ MORE

  5. 13. On a learning system for industrial automation : Model-based control and diagnostics for decision support

    Author : Moksadur Rahman; Konstantinos Kyprianidis; Anders Avelin; Gunnar Bengtsson; John Hedengren; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Learning system; Supervisory system; Pulp and paper; Micro gas turbine; Process modelling; Model-based control; Diagnostics; Decision support; Anomaly detection; Fault detection; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Access to energy is fundamental to economic and technological advancement. Hence, the more the world develops, the greater the demand for energy becomes. Evidently, the production and consumption of energy alone account for more than 80% of global anthropogenic greenhouse gas (GHG) emissions. READ MORE

  6. 14. Adapting sonar systems for monitoring ocean energy technologies

    Author : Francisco Francisco; Jan Sundberg; Mats Leijon; William Megill; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ocean energy; sonar systems; monitoring technologies; marine environment; wave power; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : The global energy sector is under profound reforms aiming towards renewable energy sources, clean technologies and expansion of smart grids, all with the additional aim of providing affordable and dependable electricity for everyone. A reduction of carbon dioxide emissions is a priority on the global agenda, and to achieve that, cleaner energy technologies has to be more integrated into the energy mix. READ MORE

  7. 15. On Tracing Flicker Sources and Classification of Voltage Disturbances
