Contingency Analysis In Restructured Power System

Maintaining power system security is one of the challenging tasks for the power system engineers. The security assessment is an essential task as it gives the knowledge about the system state in the event of a contingency. Contingency analysis is one of the basic power system studies. Contingency analysis technique is being widely used to predict the effect of outages like failures of equipment transmission line etc, and to take necessary actions to keep the power system secure and reliable. It refers to the security of the system operation under the loss of one or more of the major system components This paper shows the example of 6-Bus power system which gives the information about the violations and novel method proposed and is tested on 9-Bus system. Detailed studies have been carried out to work out the contingency analysis.
