Electric power system stability is always threatened by disturbances. These disturbances emerge in different ways. It can come as loss of generation to switching, change in loads, and fault conditions. These disturbances have caused a shift in the original desire of the utility providers and the consumers which is to maintain in power system a stable voltage at all buses to undesirable voltage instability. The effect of instability in the Nigerian power system can be severe to the network providers and also to the consumers. Untreated instability in the power system leads to a condition involving loss of synchronism of certain generators or some generators falling out of step. Voltage collapse can be caused by voltage instability. It is pertinent to note that, when the system voltage collapses, the utility end-users suffer greatly in such a way that their standard of living diminishes hence many companies seize to operate and a lot of workers lose their jobs, life becomes unbearable. Voltage instability reduces National development in a way that there will be a loss in national economic development. Companies do not thrive in a situation of instability and so the working population is reduced, so also productivity and economy. On another note when the voltage rises and falls indiscriminately, it can damage the plant, and that results in a huge economic loss in the society. Following this, therefore, there is a need to employ an intelligent technique to keep intact power steadiness in electric energy systems. Hybrid technique, that is a combination of thyristor-controlled series compensator (TCSC), Static Var Compensator, and artificial intelligence was adopted to mitigate voltage violation in transmission lines. The result showed that the hybrid technique performs better when using only TCSC or SVC.
