Concurrent Support of Important Buses using Placing Minimal Number of Phasor Measurement Components

Abstract

A mode of procedure for arrangement of Phasor Measurement Components (PMC), make sure that the support of injured buses which are achieved based on transient and voltage stability analysis process on the whole system is projected. Arrangement of PMCs can be done based on various criterions. Topological observability is one of the significant prospect that has been directed in the past thereby empower the Wide Area Support to be run totally independent from SCADA stage. The arrangement is prejudiced by the following criteria- less number of substations, less number of PMC components, observability of the topology based on the PMCs, in view of the PMC type. Concurrent support of phase angles and voltage stability indices crossways different nodes point toward the closeness to instability. The matter is to identify the injured buses where the PMCs should be positioned when the transient stability and voltage calculation is taken into report. Integer Linear Programming with equality and inequality constraints is used to detect the most excellent arrangement set with injured buses recognized from transient stability analysis. The projected mode of procedure has been examined on Indian Southern Grid 24 modified bus system in detail and the results have been included.
