  3. 3. Interruptible Load Services in Deregulated Power Market

    University dissertation from Chalmers University of Technology

    Author : Tuan Le; Chalmers tekniska högskola.; Chalmers University of Technology.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elkraftteknik; Electric power engineering; deregulated electricity market; interruptible load management; ancillary services; congestion management; reserve generation; optimal power flow;

    Abstract : Since the nineties decade, many electric utilities world-wide have been under restructuring from vertically integrated functioning to deregulated open-market system. In the erstwhile vertically integrated utilities, the system operator sought to maximize the social welfare with distributional equity (meeting the load at all time) as the main criteria, for the system as a whole.

    Abstract : Transition delay in boundary-layer flows is achieved via reactive control of flow instabilities, i.e. Tollmien-Schlichting (TS) waves. Adaptive and model-based control techniques are investigated by means of direct numerical simulations (DNS) and experiments. READ MORE

  5. 5. Probabilistic security management for power system operations with large amounts of wind power

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Camille Hamon; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power systems; wind power; probabilistic security management; chance-constrained optimal power flow; monte-carlo; importance sampling; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Power systems are critical infrastructures for the society. They are therefore planned and operated to provide a reliable eletricity delivery. The set of tools and methods to do so are gathered under security management and are designed to ensure that all operating constraints are fulfilled at all times. READ MORE
