A prerequisite to dynamic state estimation of a stochastic nonlinear dynamic model of a
power system is its observability analysis. However, due to the model nonlinearity, the …

This paper proposes an online data-driven Koopman-inspired identification and control
method for microgrid secondary voltage and frequency control. Unlike typical data-driven …

Two main tasks of online dynamic security assessment (DSA) are real-time state monitoring
and postfault transient trajectory prediction. For the first task, the model-based methods are …

This article is concerned with the global dynamic stability problem of integrated energy
system (IES) in a distributed fashion. An information energy coupling framework is …

The microgrid (MG) plays a crucial role in the energy transition, but its nonlinearity presents
a significant challenge for large-signal power systems studies in the electromagnetic …

The proliferation of unbalanced linear and nonlinear loads in microgrids degrades the
voltage quality at the inverter terminals, and thus, load terminals receive unbalanced and …

Modularized Koopman bilinear form (M-KBF) is presented to model and predict the transient
dynamics of microgrids in the presence of disturbances. As a scalable data-driven approach …
