Abstract

The voltage stability analysis and the improvement methodologies are important because increase in
demand of electricity is causing voltage drop and thermal stress which may lead to voltage collapse. A Genetic
algorithm (GA) is used to solve the optimal power flow (OPF) problem for voltage stability improvement. The voltage
stability is measured through L-index to find the vulnerable buses for the placement of compensating devices. The
control variables are identified to minimize the maximum value of L-indices. The effect of changing the number of
control variables is also studied and the algorithm is tested on IEEE 30-bus and 57-bus systems.
