Abstract
High quality generator dynamic models are critical to reliable and
accurate power systems studies and planning. With the availability of
PMU measurements, measurement-based approach for model validation has
gained significant prominence. Currently, the model validation results
are analyzed by visually comparing real--world PMU measurements with the
model-based simulated data. This paper proposes metrics to quantify the
generator dynamic model validation results based on the response of
generators to each system mode, which includes both local and
inter-area, using modal analysis approach. The metrics provide
information on the inaccuracy associated with the model in terms of the
characteristics of each mode. Initial results obtained using the
real-world data validates the effectiveness of the proposed metrics. In
this paper, modal analysis was carried out using Prony method.
