New line voltage stability index (BVSI) for voltage stability assessment in power system: the comparative studies

Modern power utilization has been forced to operate close to their stability limits, which may lead to voltage instability or collapse owing to the stressed operating conditions of networks. This raises the need to develop a new technique to predict the level of voltage security under different oper...
