Abstract

Todays, contingency analysis is being used to predict the effect of line outages in power system operation. This analysis is mostly offline to predict the line outage effects on the blackout of power system. To investigate the grid’s sensitivity to each line outage, power flow equations are analyzed. The ranking process of line outage and their effects on the other lines overloading is done by calculating an index (PI MVA) which represents the sum of deviations of each line power from the maximum rating of the line. Furthermore the effect of wind farm connection to the grid is investigated to improve the sensitivity of the grid in line outage contingencies. The effectiveness of the method is tested on IEEE-14 Bus standard benchmark. The simulations are done, using ETAP software.
