Voltage and reactive power distribution factors for line, transformer and generator outage studies

This paper reports the development of a fast and efficient method to calculate a new set of voltage and reactive power distribution factors for line, transformer and generator outage studies. The new distribution factors have been derived using base load flow results and an efficient method exploiting the property of Newton-Raphson load flow (NRLF) Jacobian available at the end of a base load flow. The factors can be used for rapid computation of the post-outage bus voltage magnitudes and outputs of reactive power sources.<
