    Accurate reduced-order models for heterogeneous coherent generators
    (2021) Min, Hancheng; Paganini, Fernando; Mallada, Enrique
    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.
