  1. 1. Interruptible Load as an Ancillary Service in Deregulated Electricity Markets

    Författare :Anh Tuan Le; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reserve generation; least-cost planning.; interruptible load management; optimal power flow; ancillary services; deregulated electricity market; congestion management;

    Sammanfattning : Power companies world-wide have been restructuring their electric power systems from a vertically integrated entity to a deregulated, open-market environment. Previously, electric utilities usually sought to maximize the social welfare of the system with distributional equity as its main operational criterion. LÄS MER

  3. 2. Interruptible Load Services in Deregulated Power Market

    Författare :Anh Tuan Le; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; congestion management; deregulated electricity market; ancillary services; optimal power flow; reserve generation; interruptible load management;

    Sammanfattning : 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.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; perpendicular magnetic anisotropy; tilted-polarizer; spintronics; STT; MTJ; pseudospin-valve; STO; ST-FMR; magnonics; magnetic droplet; droplet nucleation; droplet annihilation; vinkelrät magnetisk anisotropi; lutande polarisator; spinntronik; STT; MTJ; pseudospinnventil; STO; ST-FMR; magnonics; magnetisk droppe; nukleering av droppe; anihilering av droppe.; Physics; Fysik;

    Sammanfattning : Spin-torque transfer (STT) effects have brought spintronics ever closer to practical electronic applications, such as MRAM and active broadband microwave spin-torque oscillator (STO), and have emerged as an increasingly attractive field of research in spin dynamics. Utilizing materials with perpendicular magnetic anisotropy (PMA) in such applications offers several great advantages such as low-current, low-field operation combined with high thermal stability.
