Contingency Analysis and Security Constraint based Optimal Power Flow in Power Network

The objective of the present work is to observe the application of security constraint optimal power flow (SCOPF) technique in contingency management of power system. The contingency situations in power networks such as line outages and generation outages have been managed by using SCOPF solutions. The generation levels of various generators have been optimally rescheduled during contingent situation using SCOPF based load dispatch technique. In SCOPF, various other system constraints such as congestion, voltage deviation, and loss minimization have also been taken into account to achieve economic performance in the system. The interior point method (IPM) technique has been used to obtain the test results. The IPM based SCOPF methodology has been tested on an IEEE-9 bus system. The obtained test results show that the IPM based SCOPF technique provides efficient solutions for economic load dispatch in power network during normal and contingent situation of line and generation outages.
