Our Vision for EMS Evolution

PMU measurement-based methods

monitor grid stability in real-time:

– Track current damping levels

– Detect & alarm stability risks & sudden events

PREDICT & MITIGATE

MONITOR

OPERATING POINT

PREDICT & MITIGATE


Model-based techniques (SSAT, TSAT, VSAT)

provide the predictive component (i.e. ‘what-if’ analysis)

– Available MW transfer capability (‘distance’ to the edge)

– Assess impact of critical contingencies. (e.g. change in damping)

– Recommend controls based on sensitivity information.
