Abstract :
This paper presents the development of a simple and fast method to calculate a new set of distribution factors using the sensitivity property of Newton-Raphson load flow Jacobian at a base operating point. These factors have been used to calculate the post-outage voltages and reactive power output of the sources following outage of a transmission branch or a generator. The accuracy of post-outage results using these distribution factors has been established with respect to full AC load flow results on IEEE 14-bus, IEEE 57-bus and a practical 75-bus Indian power systems
