As power systems transit to a state of high renewable penetration, little or no presence of
synchronous generators makes the prerequisite of well-regulated frequency for grid …

We present a novel grid-forming control design approach for dynamic virtual power plants
(DVPP). We consider a group of heterogeneous grid-forming distributed energy resources …

We investigate coherent oscillations in large scale transmission power grids, where large
groups of generators respond in unison to a distant disturbance. Such long wavelength …

We propose a structure-preserving model-reduction methodology for large-scale dynamic
networks with tightly-connected components. First, the coherent groups are identified by a …

The ability to achieve coordinated behavior--engineered or emergent--on networked
systems has attracted widespread interest over several fields. This interest has led to …

We introduce a novel framework to approximate the aggregate frequency dynamics of
coherent generators. By leveraging recent results on dynamics concentration of tightly …

Accurately modeling generator frequency response to power disturbances is essential for
assessing frequency control performance in power grids. A widely used technique is to …

Network coherence generally refers to the emergence of simple aggregated dynamical
behaviours, despite heterogeneity in the dynamics of the subsystems that constitute the …

We propose a novel model-reduction methodology for large-scale dynamic networks with
tightly-connected components. First, the coherent groups are identified by a spectral …

The physical and cyber domains with which we interact are filled with high-dimensional
dynamical systems. In machine learning, for instance, the evolution of overparametrized …
