Situational Awareness with PMUs and SCADA
For power system operators, this method improves state estimation accuracy by combining costly PMU data with widely available SCADA data.
The paper proposes a new state estimation method that integrates PMU and SCADA measurements to enhance situational awareness in power systems, demonstrating outstanding performance.
Phasor measurement units (PMUs) are integrated to the transmission networks under the smart grid umbrella. The observability of PMUs is geographically limited due to their high cost in integration. The measurements of PMUs can be complemented by those from widely installed supervisory control and data acquisition (SCADA) to enhance the situational awareness. This paper proposes a new state estimation method that simultaneously integrate both measurements, and show an outstanding performance.
