Abstract

Abstract: The practical power systems undergo variable load throughout the year. Maintaining security and reliability in operation of these structures in such a vulnerable scenario is a huge challenge. In this paper, a line utilisation contingency distribution index (LUCDI) has been proposed for obtaining the weakest line of the real-time power system in cases of contingency. The contingency analysis has been executed for every hour load of the IEEE 30-bus system. The LUCDI has been computed for every transmission line of the power system for the severe-most outage, which specifies the stress on the transmission lines as a result of contingency for a real-time load. An interline power flow controller (IPFC) has been positioned and tuned to recover the system from the post-contingency condition. A function with multiple objectives has been used for tuning the IPFC using differential evolution and results have been evaluated to highlight the benefits of an IPFC for management of post-contingency condition in a real-time context.
