    Allocation of available transfer capability in planning horizon

    , Article European Transactions on Electrical Power ; Volume 21, Issue 3 , 2011 , Pages 1437-1454 ; 1430144X (ISSN) Rajabi Ghahnavieh, A ; Fotuhi Firuzabad, M ; Feuillet, R ; Sharif University of Technology
    In the United States electricity market standard, when several transmission service requests (TSRs) are made for a specific pair of power injection/extraction points, the independent system operator (ISO) must allocate the available transmission capability (ATC) associated with the pair to the requests. An ATC allocation must determine the amount of accepted requests as well as the priority of the accepted requests during emergencies. The requests could have different types (recallable/non-recallable), tariffs, and time frames and these factors must be properly considered in ATC allocation. This paper proposes a method for optimal ATC allocation in the planning horizon which incorporates the... 

    A Penalty Method for Mixed-Integer Optimization

    , M.Sc. Thesis Sharif University of Technology Piruzbakht, Hassan (Author) ; Mahdavi-Amiri, Nezamoddin (Supervisor)
    Linear and nonlinear problems on integer and real numbers constitute very important optimization problems. Recently, methods have been developed using pumps to solve this type of problem. Feasibility pumps usually produce random perturbations. In this method,the generated random perturbations are replaced by a penalty framework and feasibility pumps are introduced as methods of displacement. Feasibility pump algorithms on 0-1 are used to solve these problems and the alternating direction methods are used. A convergence theorem is presented for the alternate direction method based on the penalty.New changes to the feasibility pumps and existing algorithms for solving linear and nonlinear...
