Optimal reactive power planning using oppositional grey wolf optimization by considering bus vulnerability analysis

open access: yesEnergy Conversion and Economics, 2022
Power system instability primarily results from the deviation of the frequency from its predefined rated value. This deviation causes voltage collapse, which further leads to sudden blackouts of the power system network.
