Phase shifter optimization in security constrained scheduling applications

Security constrained scheduling has been widely applied to the operations planning and control of the power system. The advent of deregulation has made such an application even more critical as power systems are operated under increasing stress with all market participants having open access to the transmission network. This paper presents a methodology for the phase shifter optimization in the security constrained scheduling applications. Modeling of phase shifter regulation in the power flow solution and optimization are described. Representative test results obtained from a security constrained unit commitment are shown to demonstrate the economic benefits and effectiveness of the developed methodology.
