Due to physical or control-related limitations, some dynamic state variables are constrained,
such as the regulated voltage, the exciter reference voltage, etc. In addition, there exists a …

In this paper, a hybrid measurement-and model-based method is proposed which can
estimate the dynamic state Jacobian matrix and the dynamic system state matrix in near real …

Sustained oscillations observed in power systems can damage equipment, degrade the
power quality and increase the risks of cascading blackouts. There are several mechanisms …

In this paper, the variable wind power is incorporated into the dynamic model for long-term
stability analysis. A theory-based method is proposed for power systems with wind power to …

The knowledge of the steady-state security region is essential for secure operation of the
integrated energy system (IES). The two-time-scale feature of the IES is explored to facilitate …

Microturbines (MTs) are among the most successfully commercialized distributed energy
resources, especially when they are used for combined heat and power generation …

In this paper, a purely measurement-based method is proposed to estimate the dynamic
system state matrix by applying the regression theorem of the multivariate Ornstein …

We propose a framework employing stochastic differential equations to facilitate the long-
term stability analysis of power grids with intermittent wind power generations. This …

This paper presents a novel methodology for the calculation of angular indexes of an
electrical system from stationary analysis, using load flow and nose curves (P–V) in each of …

In this paper, we demonstrate the interdependence among buses in power systems that
experience voltage instability events by deriving interaction graphs through successive …
