Optimal PMU Placement based on Voltage Stability Index for
Observability of Network
Authors: , , , ,
Abstract: This work presents a voltage stability Index (FLVSI) for optimal PMU placement (OPP) to achieve
complete network observability. Every PQ bus is considered in the FLVSI strategy to attain weak PQ bus from
PMUs are conditioned to allocate at weak PQ buses using ILP approach to attain observability of network. Zero
Injection (ZIB) modeling is introduced to minimize PMU places in the network. The redundancy Index (RI) is
formulated to compute redundancy for all buses in the network. IEEE –14 -39 and 118- bus networks are
programmed in MATLAB and compared with standard techniques to present their efficacy.
