Impedance-based analysis of harmonic instabilities in HVDC-connected Offshore Wind Power Plants
(2019-03-01)
Article
Restricted access - publisher's policyHVDC-connected Offshore Wind Power Plants (OWPPs) with a large number of power converters are prone to instabilities due to interactions with converter controllers. This paper analyzes harmonic instabilities in OWPPs ... -
Parameter identification of DC-DC converters under steady-state and transient conditions based on white-box models
(2018-12-05)
Article
Open AccessThis paper proposes a white-box approach for identifying the parameters of DC-DC buck and boost switch mode power converters. It is based on discretizing the differential equations that describe the dynamic behavior of the ... -
Harmonic resonance stability of aeronautical ground lighting systems
(Institute of Electrical and Electronics Engineers (IEEE), 2018-12)
Article
Restricted access - publisher's policyAeronautical ground lighting (AGL) systems assist aircraft pilots in airport operations. These systems are singlephase series circuits where constant current regulators (CCRs) feed luminaires with an adjustable rms current. ... -
Multi-objective design optimization using dual-level response surface methodology and booth's algorithm for permanent magnet synchronous generators
(2017-11-22)
Article
Restricted access - publisher's policyThis paper studies a dual-level response surface methodology (DRSM) coupled with Booth's algorithm using a simulated annealing (BA-SA) method as a multi-objective technique for parametric modeling and machine design ... -
Positive-net-damping stability criterion in grid-connected VSC systems
(Institute of Electrical and Electronics Engineers (IEEE), 2017-12-01)
Article
Open AccessResonance instabilities in power systems can be assessed with the positive-net-damping stability criterion. This criterion is a review of the complex torque coefficients method, but it does not provide the frequency of the ... -
Resonance-based procedure for locating failed luminaires in AGL systems
(2018-02)
Article
Open AccessIEEE Aeronautical ground lighting (AGL) systems provide a visual reference for aircraft during airport operations. Fast detection and location of failed luminaires is an important safety concern in AGL systems. In the event ... -
