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 …

The presence of power system uncertainties results in variations of the harmonic resonance
behaviors. There is, therefore, a need to perform the probabilistic assessment in harmonic …

This paper describes two network models which allow several harmonic and
electromagnetic transient analysis, being, therefore, more flexible than conventional ones. In …

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 …

This paper proposes an improved generalized pole clustering technique for model order
reduction of higher-order LTI systems. The method has been modified from the traditional …

提出了一套计及主导系数, 相关系数及敏感度指标的电网谐振源辨识方法. 首先 …

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 …

This paper proposes a model reduction technique that simplifies the dynamic equations of
complex power networks, using sparse representations of the system matrices. Instead of …
