Fast Load Voltage Stability Index constrained PMU Placement for Complete Observability

open access: yesInternational Journal of Engineering and Technology, 2018
This paper proposes a Fast Load Voltage Stability Index (FLVSI) constrained Binary Integer Programming (BIP) method for Phasor Measurement Unit placement at optimal locations in network to obtain complete observability. Every load bus of network is considered to sort out weak load bus from proposed FLVSI approach.

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.
