PBC approach applied on a DC-DC step-down converter for providing service to CPLs
(Institute of Electrical and Electronics Engineers Inc., 2019)
This paper addresses the problem of output voltage regulation for step-down converters (buck converters) for constant power load (CPL) applications. The model of the CPL corresponds to a hyperbolic constraint that introduces ...
PBC Approach for SMES Devices in Electric Distribution Networks
(Institute of Electrical and Electronics Engineers Inc., 2018)
This express brief presents a nonlinear active and reactive power control for a superconducting magnetic energy storage (SMES) system connected in three-phase distribution networks using pulse-width modulated current-source ...
Output Voltage Regulation for DC-DC Buck Converters: A Passivity-Based PI Design
(Institute of Electrical and Electronics Engineers Inc., 2019)
This paper presents a global tracking passivity-based proportional-integral (PI) control for output voltage regulation of a DC-DC Buck converter. The proposed controller is based on passivity formulation since DC-DC Buck ...
Passivity-Based Control for Hydro-Turbine Governing Systems
(Institute of Electrical and Electronics Engineers Inc., 2018)
In this paper an interconnection and damping assignment passivity-based control (IDA-PBC) applied to the hydro-Turbine governing systems (HTGS) is proposed to regulate the relative deviation of turbine speed in single ...
SCES Integration in Power Grids: A PBC Approach under abc, αβ0 and dq0 Reference Frames
(Institute of Electrical and Electronics Engineers Inc., 2018)
This paper presents an integration of three-phase supercapacitor energy storage (SCES) in power grids via passivity-based control (PBC) theory under different reference frames. The SCES systems have the possibility to ...
VSC with direct PI power control for frequency compensation in a microgrid: A PBC approach
