  1. 1. 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.
