Model Reduction for Inverters with Current Limiting and Dispatchable Virtual Oscillator Control
Olaoluwapo Ajala, Minghui Lu, Brian Johnson +2
This paper outlines reduced-order models for grid-forming virtual-oscillator-controlled inverters with nested current- and voltage-control loops, and current-limiting action for ov…
Data-Driven Secondary Control of Distributed Energy Resources
Madi Zholbaryssov, Alejandro D. Dominguez-Garcia
In this paper, we present a data-driven secondary controller for regulating to some desired values several variables of interest in a power system, namely, electrical frequency, vo…
Robust synchronization of electric power generators
Olaoluwapo Ajala, Alejandro Dominguez-Garcia, Daniel Liberzon
We consider the problem of synchronizing two electric power generators, one of which (the leader) is serving a time-varying electrical load, so that they can ultimately be connecte…
Fast Distributed Coordination of Distributed Energy Resources Over Time-Varying Communication Networks
Madi Zholbaryssov, Christoforos N. Hadjicostis, Alejandro D. Dominguez-Garcia
In this paper, we consider the problem of optimally coordinating the response of a group of distributed energy resources (DERs) so they collectively meet the electric power demande…
Data-driven Voltage Regulation in Radial Power Distribution Systems
Hanchen Xu, Alejandro D. Domínguez-García, Venugopal V. Veeravalli +1
In this paper, we develop a data-driven voltage regulation framework for distributed energy resources (DERs) in a balanced radial power distribution system. The objective is to det…
Optimal Tap Setting of Voltage Regulation Transformers Using Batch Reinforcement Learning
Hanchen Xu, Alejandro D. Domínguez-García, Peter W. Sauer
In this paper, we address the problem of setting the tap positions of load tap changers (LTCs) for voltage regulation in radial power distribution systems under uncertain load dyna…
