Fast Load Voltage Stability Index constrained PMU Placement for Complete Observability

International Journal of Engineering & 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.
