This study presents a circuit theory approach for voltage stability assessment in an interconnected power network. Here, an interconnected IEEE 14-bus network has been reconfigured into 12-, 10- and 8-bus networks using graph theory. The line index indicator has been used for voltage stability assessment under normal and faulted conditions for the original (IEEE 14-bus) and the reconfigured (12-, 10- and 8-bus) networks. Genetic algorithm tool in MATLAB has been used to determine the optimal operating condition with best voltage stability for the original and the reconfigured networks. The results have shown that the voltage stability assessment under normal and faulted conditions can be effectively determined for the reconfigured networks compared with the original network.
