  2. 1. Power from the Brave New Ocean - Marine Renewable Energy and Ecological Risks

    Author : Linus Hammar; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stereo-video; OTEC; Environmental impact; Ocean thermal energy conversion; Fish; Ecological risk assessment; Wave power; Tidal power; Offshore wind power; Ocean energy;

    Abstract : This thesis address ecological risks associated with the possible growth of marine renewable energy. Tidal power, wave power, ocean thermal energy conversion (OTEC) and currently expanding offshore wind power are likely to become common components of future seascapes. READ MORE

  4. 2. Medium Voltage Generation System with Five-level NPC Converters for Kite Tidal Power

    Author : Georgios Mademlis; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Voltage balancing; Maximum Power Point Tracking MPPT ; Medium Voltage Converters; Multilevel Space-Vector-Modulation; Neutral point clamped converter NPC ; Subsea kite; Tidal power;

    Abstract : Offshore power generation has emerged as a prominent source of energy and the installed capacity of new plants has been steadily increasing in recent years. Tidal power specifically is a promising renewable energy source which has not been highly exploited yet, despite its distinctive advantages of being predictable and independent of weather conditions.

  5. 3. Wind Power and Natural Disasters

    Author : Jon Olauson; Mikael Bergkvist; Stefan Ivanell; Uppsala universitet; []
    Keywords : Wind power; Natural disasters; Hybrid energy system; Meteorological model; Statistical model; Variability; Wind power integration;

    Abstract : Wind power can be related to natural disasters in several ways. This licentiate thesis gives some background and introduces four papers devoted to two aspects of this relation. The first section looks into how small-scale wind energy converters (WECs) could be used to generate power after a natural disaster. READ MORE

  6. 4. Towards Technology Assessment of Ocean Energy in a Developing Country Context

    Author : Linus Hammar; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electricity; Indian Ocean; technology assessment; ocean energy; Africa; rural electrification; ocean thermal energy conversion; wave power; tidal power;

    Abstract : New technologies for the extraction of valuable ocean resources are emerging: renewable ocean energy. Ocean energy technologies have so far primarily been developed in industrialized countries but will be deployed in both industrialized and developing countries. READ MORE

  7. 5. Inverter Design for SiC-based Electric Drive Systems with Optimal Redundant States Control of Space Vector Modulation

    Author : Georgios Mademlis; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Vehicle; Common Mode Voltage; Power Hardware-in-the-Loop; Tidal power; Voltage balancing; Silicon Carbide SiC ; Medium Voltage Converters; Multilevel; Neutral Point Clamped NPC ; Maximum Power Point Tracking MPPT ; Space Vector Modulation;

    Abstract : The need for inverters with ever increasing power density and efficiency has recently become the driving factor for research in various fields. Increasing the operating voltage of the whole drive system and utilizing newly developed SiC power switches can contribute towards this goal. READ MORE
