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

This paper presents a linearized HVDC link model, which was implemented in PacDyn
software and is applicable to dynamic performance studies of power electronic equipment …

The potential instability issues caused by the dynamic interactions between parallel grid-
forming inverters are examined. The approach adopted for analysis is s-domain admittance …

With the increasing utilization of power electronic equipment in power systems, there has
been an increase in the occurrence of oscillatory behavior from unknown sources in recent …

In order to study the harmonic resonance characteristics of single-stage photovoltaic (PV)
grid-connected/hydrogen production multi-inverter system, the modal analysis method was …

The time-varying harmonics in power systems are not only caused by the stochastic
harmonic emissions from different types of harmonic sources, but also the uncertain …

Background: Harmonic resonance is one of the apprehensive power quality problems in
electric railway traction power supply systems. Harmonic resonances result in big harmonic …

Abstract The Routh–Hurwitz criterion is one of the most popular methods to study the
stability of polynomials with real coefficients, given its simplicity and ductility. However, when …

The randomness and fluctuation of wind power output will cause certain waste in capacity
allocation of integrated energy system. Therefore, a robust chance constrained optimization …
