Modern control algorithms in the emerging power systems process information delivered mainly by distributed, synchronized measurement systems, and available in data streams with different reporting rates. Beyond existing measurement approaches currently embedded in SCADA framework and smart meters, there are more and more deployed high-reporting rate, synchronized measurement devices like phasor measurement units (PMUs).
There are several applications where synchronized data received with high reporting rate has to be used together with aggregated data from measurement equipment having a lower reporting rate (complying, for example, with power quality data aggregation standards) and the question is how adequate the energy transfer lossy information models are and how to correlate the measurement data streams.
The talk will address:
- The measurement paradigm in power systems;
- Definitions of main quantities to be controlled in power systems;
- Voltage and frequency variability;
- Model uncertainty and measurement sources of errors;
- Information compression by the existing measurement systems
- Phasor Measurement Units
- Linear and hybrid state estimators; WAMC
