Voltage and reactive power distribution factors calculated by genetic algorithms

This paper presents improved voltage and reactive power distribution factors, calculated by genetic algorithms. Deficiencies of the traditional sensitivity based linear methods are first overcome by constructing a bounded optimization procedure between the reactive power flows and the voltage magnitudes. This optimization problem is later solved by using genetic algorithms. The accuracy of the calculated post-outage voltage magnitudes and reactive power flows was tested on the IEEE 14-bus and IEEE 57-bus test systems.
