A New Adaptive Phase-locked Loop for Synchronization of a Grid-Connected Voltage Source Converter: Simulation and Experimental Results
Wei He, Jiachen Yan, Romeo Ortega +1
In [1] a new adaptive phase-locked loop scheme for synchronization of a grid connected voltage source converter with guaranteed (almost) global stability properties was reported. T…
An Observer-Based Composite Identifier for Online Estimation of the Thevenin Equivalent Parameters of a Power System
Daniele Zonetti, Romeo Ortega, Rafael Cisneros +3
We consider a Thévenin equivalent circuit capturing the dynamics of a power grid as seen from the point of common coupling with a power electronic converter, and provide a solution…
An Almost Globally Stable Adaptive Phase-Locked Loop for Synchronization of a Grid-Connected Voltage Source Converter
Daniele Zonetti, Alexey Bobtsov, Romeo Ortega +2
In this paper we are interested in the problem of adaptive synchronization of a voltage source converter with a possibly weak grid with unknown angle and frequency, but knowledge o…
Passivity-based design and analysis of phase-locked loops
Daniele Zonetti, Oriol Gomis-Bellmunt, Eduardo Prieto-Araujo +1
We consider a grid-connected voltage source converter (VSC) and address the problem of estimating the grid angle and frequency, information that is essential for an appropriate ope…
PID passivity-based droop control of power converters: Large-signal stability, robustness and performance
Daniele Zonetti, Gilbert Bergna-Diaz, Romeo Ortega +1
We present a full review of PID passivity-based controllers (PBC) applied to power electronic converters, discussing limitations, unprecedented merits and potential improvements in…
A tool for stability and power sharing analysis of a generalized class of droop controllers for high-voltage direct-current transmission systems
Daniele Zonetti, Romeo Ortega, Johannes Schiffer
The problem of primary control of high-voltage direct current transmission systems is addressed in this paper, which contains four main contributions. First, to propose a new nonli…
A survey on modeling of microgrids - from fundamental physics to phasors and voltage sources
Johannes Schiffer, Daniele Zonetti, Romeo Ortega +3
Microgrids have been identified as key components of modern electrical systems to facilitate the integration of renewable distributed generation units. Their analysis and controlle…
Modeling and Control of High-Voltage Direct-Current Transmission Systems: From Theory to Practice and Back
Daniele Zonetti, Romeo Ortega, Abdelkrim Benchaib
The problem of modeling and control of multi-terminal high-voltage direct-current transmission systems is addressed in this paper, which contains five main contributions. First, to…
