Abstract
We introduce a novel framework to approximate
the aggregate frequency dynamics of coherent generators.
By leveraging recent results on dynamics concentration
of tightly connected networks, and frequency weighted
balanced truncation, a hierarchy of reduced-order models
is developed. This hierarchy provides increasing accuracy
in the approximation of the aggregate system response,
outperforming existing aggregation techniques.
