Eigenvalue and eigenvector derivatives with respect to system design variables and their
applications have been and continue to be one of the core issues in the design, control and …

Since the beginning of railway electrification, power quality has been a main problem in
railway networks because of their special characteristics. Many ways of power quality …

High-frequency harmonic resonance has occurred frequently in the traction power-supply
system (TPSS) when high-speed trains that are equipped with pulsewidth-modulation …

In order to make high-speed trains (HSTs) lighter and more reliable, LC or LCL high-pass
filters, which are widely adopted to mitigate high-order harmonics, are not installed in most …

This paper presents a qualitative overview of the main developments carried out by the
Brazilian Electrical Energy Research Center and the Brazilian Power System Operator to …

Harmonic resonance is closely related to the singularity of a network admittance matrix. The
smallest eigenvalue of the matrix defines the mode of harmonic resonance. This paper …

Harmonic resonances exist inherently in power systems with varying affected areas and
amplification levels. This paper presents a quantitative harmonic resonance assessment …

Resonance-mode analysis is effective to determine the contributions of different network
components to a resonance in power system harmonic studies. There are two forms of …

This paper investigates the impact of positive-feedback anti-islanding methods on the small-
signal stability of grid-connected inverter-based distributed generation. The maximum power …

This paper demonstrates that transfer function zeros are equal to the poles of a new inverse
system, which is valid even for the strictly proper case. This is a new finding, which is …
