The restructuring of the Electric Power industry has resulted in newlineparadigm shifts for the real time control activities of the Power grids Power newlineDispatch is one of the important control activities and the Optimal Power newlineFlow OPF is the most significant tool to obtain minimum cost generation newlinepatterns with transmission and operational constraints The role of an newlineIndependent System Operator ISO in a restructured competitive market newlineenvironment would be to facilitate the complete dispatch of the power that newlinegets contracted among the market players With the trend of an increasing newlinenumber of bilateral contracts being signed for electricity market trades the newlinepossibility of insufficient resources leading to network congestion may be newlineunavoidable In this scenario congestion management with OPF framework newlinebecomes an important issue Relieving congestion process may involve newlinerescheduling of generations along with the employment of FACTS devices newlineand load shedding newline newline
