Methodology for Zero-moment Point Experimental Modeling in the Frequency Domain
(2006-06-28)
Frequency domain methodology is applied to obtain a nominal model for the Zero-Moment Point (ZMP) stability index of a biped robot in an attempt to establish a relationship between the robot trunk trajectories and the ...
Flywheel energy storage system to fast-frequency response provision on insular power systems from a microgrid perspective
(IEEE. Institute of Electrical and Electronics Engineers, 2022)
This paper discusses a flywheel study case assessment in one of the Galapagos Islands’ power systems. This network is essentially a microgrid in islanding operation with high penetration of wind energy generation, therefore ...
Robust Unit Commitment including Frequency Stability Constraints
(2016)
An increased use of variable generation technologies such as wind power and photovoltaic generation can have important effects on system frequency performance during normal operation as well as contingencies. The main ...
Conformer determination of stabilized triphenyl phosphonium acyl ylides by infrared spectroscopy
(2009)
Stretching frequencies of acyl groups of stabilized triphenyl phosphonium ylides with ester, keto or cyano groups depend in part on the orientations of the acyl groups, syn or anti, with respect to phosphorus. Frequencies ...
Analysis of electric torque in single machine-infinite bus system using phase shifters
(2008-12-01)
ResumoThe main idea of this work is based on the analysis of the electric torque through the acting of the PS in the power system, provided of a control for the compensation degree (PSC). A linear model of the single ...
