Integrated System Models for Networks with Generators & Inverters
D. Venkatramanan, Manish K. Singh, Olaolu Ajala +2
Synchronous generators and inverter-based resources are complex systems with dynamics that cut across multiple intertwined physical domains and control loops. Modeling individual g…
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…
Distributed Optimal Power Flow Algorithms Over Time-Varying Communication Networks
Madi Zholbaryssov, Alejandro D. Dominguez-Garcia
In this paper, we consider the problem of optimally coordinating the response of a group of distributed energy resources (DERs) in distribution systems by solving the so-called opt…
Utilization of Water Supply Networks for Harvesting Renewable Energy
Dariush Fooladivanda, Alejandro D. Domínguez-García, Peter W. Sauer
Renewable surplus power is increasing due to the increasing penetration of these intermittent resources. In practice, electric grid operators either curtail the surplus energy resu…
A library of second-order models for synchronous machines
Olaoluwapo Ajala, Alejandro Dominguez-garcia, Peter Sauer +1
This paper presents a library of second-order models for synchronous machines that can be utilized in power system dynamic performance analysis and control design tasks. The models…
Distributed Algorithms for Consensus and Coordination in the Presence of Packet-Dropping Communication Links - Part II: Coefficients of Ergodicity Analysis Approach
Nitin H. Vaidya, Christoforos N. Hadjicostis, Alejandro D. Dominguez-Garcia
In this two-part paper, we consider multicomponent systems in which each component can iteratively exchange information with other components in its neighborhood in order to comput…
Distributed Algorithms for Consensus and Coordination in the Presence of Packet-Dropping Communication Links - Part I: Statistical Moments Analysis Approach
Alejandro D. Dominguez-Garcia, Christoforos N. Hadjicostis, Nitin H. Vaidya
This two-part paper discusses robustification methodologies for linear-iterative distributed algorithms for consensus and coordination problems in multicomponent systems, in which…
