  2. 1. Grid Integration and Impact of a Wave Power System

    Author : Arvind Parwal; Cecilia Boström; Damir Šljivac; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ANN; buck-boost converter; current control; energy storage system; force control; flicker; FPGA control; grid integartion; harmonics; linear generator; PHIL; microgrid; voltage variation; wave energy; WEC; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Increasing energy consumption and concern for carbon emissions has boosted the demand for renewable energy production. The focus on renewable energy has gained much attention in wind, solar, hydro and wave power generations. Wave power has great potential due to its high energy density but there are challenges as well. READ MORE

  4. 2. Modeling, Control and Protection of Low-Voltage DC Microgrids

    Author : Daniel Salomonsson; Lennart Söder; Brian K. Johnsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circuit transient analysis; dc power systems; dispersed storage and generation; load modeling; power conversion; power distribution control; power distribution faults; power distribution protection; power electronics; Electric power engineering; Elkraftteknik;

    Abstract : Current trends in electric power consumption indicate an increasing use of dc in end-user equipment, such as computers and other electronic appliances used in households and offices. With a dc power system, ac/dc conversion within these loads can be avoided, and losses reduced. READ MORE

  5. 3. Agent-Based System for Enhanced Controlling and Monitoring of a Solar Driven DC Microgrid

    Author : Diana Rwegasira; Hannu Tenhunen; Anders Hallén; Masoumeh Ebrahimi; Josep M Guerrero; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : The early efforts in grid computing started as a project to link supercomputing sites, but have now grown far beyond their original intent. This has led to the introduction of smart systems such as smart grids for power systems, and e-health systems for the health sector. READ MORE

  6. 4. On Deep Machine Learning Based Techniques for Electric Power Systems

    Author : Ebrahim Balouji; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deep Learning; Cable faults; phase locked loop; Flicker; Harmonics and Interharmonics; Reinforcement learning; Voltage Dip; Active Power filter; Machine Learning; Voltage fluctuation; Partial Discharges;

    Abstract : This thesis provides deep machine learning-based solutions to real-time mitigation of power quality disturbances such as flicker, voltage dips, frequency deviations, harmonics, and interharmonics using active power filters (APF). In an APF the processing delays reduce the performance when the disturbance to be mitigated is tima varying. READ MORE
