A Unified Processing Method for Hybrid Measurements in State Estimation under Changed Measurement Triggering Mode

Abstract

The changed measurement triggering mode (CMTM) of state estimation (SE) is presented. Measurements from SCADA and WAMS can be handled uniformly under this mode. The sensitivity relationship among state, measurements and estimated power is analyzed and the tracking SE algorithm based on sensitivity analysis is presented. At each triggering moment, only the… (More)
