Hybrid dynamical systems, ie, systems that have both continuous and discrete states, are
ubiquitous in engineering but are difficult to work with due to their discontinuous transitions …

This work presents a technique to estimate on-line the inertia of a power system based on
ambient measurements. The proposed technique utilizes the covariance matrix of these …

In many engineering areas complex systems are composed of sub-parts that are modeled
and analyzed in very different ways. These subsystems are often heterogeneous parts of the …

This paper presents a unified power flow algorithm for large and complex mixed ac/dc power
systems based on the partitioning of power grids, a version of the two-level Newton method …

In many engineering domains, complex systems are composed of several interconnected
and interacting parts that are modeled and analyzed in different ways. This is the case, for …

This letter studies the impact of the dead-band in the input signal of power system stabilizers
(PSSs) on the transient response of power systems. The letter provides a taxonomy of the …

Nonlinearities have been the major obstructions that limit the computational efficiency in
power electronic circuit simulation for a long time. Yet there is no standard way for dealing …

Instability and oscillation issues originating in high-voltage direct current (HVDC) systems
comprising modular multilevel converters (MMCs) are gaining increasing interest in the …

Modular multilevel converters have become the technology of choice in high voltage direct
current systems. They are composed of a large number of submodules, which poses …

An approach allowing the on-target computation of efficiency and yield of large (hundreds of
kW), grid-connected photovoltaic (PV) parks is presented. An efficiency metric is used to …
