Abstract
A Security-Constrained Optimal Power Flow (SCOPF) process employing a quadratic programming (QP) primal-dual interior point (IP) solution method. The IP method efficiently solves practical SCOPF problems involving large numbers of contingencies and controls in preventive and preventive/corrective operating modes. An EMS system is described incorporating the inventive SCOPF process. The SCOPF process can be used in a variety of additional arrangements including a locational marginal pricing scheme and a power transmission rights auction system. An infeasibility detection method is also described.
