Control of distributed energy resources for reactive power support
Robbins, B. A.; Domínguez-Garcia, A. D.; Hadjicostis, Christoforos N. (2011)This paper proposes a method to utilize distributed energy resources (DERs) to provide reactive power support for voltage control in electric power systems. Rather than controlling each of these resources directly, a ...

Convergence rate of a distributed algorithm for matrix scaling to doubly stochastic form
Domínguez-Garcia, A. D.; Hadjicostis, Christoforos N. (Institute of Electrical and Electronics Engineers Inc., 2014)Motivated by matrix scaling applications and, more recently, distributed averaging previous work has considered settings where the interconnections between components in a distributed system are captured by a strongly ...

Coordination and control of distributed energy resources for provision of ancillary services
Domínguez-Garcia, A. D.; Hadjicostis, Christoforos N. (2010)This paper discusses the utilization of distributed energy resources on the distribution side of the power grid to provide a number of ancillary services. While the individual capability of these resources to provide grid ...

Decentralized optimal dispatch of distributed energy resources
Domínguez-Garcia, A. D.; Cady, S. T.; Hadjicostis, Christoforos N. (2012)In this paper, we address the problem of optimally dispatching a set of distributed energy resources (DERs) without relying on a centralized decision maker. We consider a scenario where each DER can provide a certain ...

Distributed algorithms for control of demand response and distributed energy resources
Domínguez-Garcia, A. D.; Hadjicostis, Christoforos N. (2011)This paper proposes distributed algorithms for control and coordination of loads and distributed energy resources (DERs) in distribution networks. These algorithms are relevant for load curtailment control in demand response ...

Distributed balancing in digraphs under interval constraints
Hadjicostis, Christoforos N.; Domínguez-Garcia, A. D. (Institute of Electrical and Electronics Engineers Inc., 2016)We consider networks the nodes of which are interconnected via directed edges, each able to admit a flow within a certain interval, with nonnegative end points that correspond to lower and upper flow limits. The paper ...

Distributed Balancing of Commodity Networks Under Flow Interval Constraints
Hadjicostis, Christoforos N.; Domínguez-Garcia, A. D. (2018)We consider networks the nodes of which are interconnected via directed edges, each able to admit a flow (or weight) within a certain interval, with nonnegative end points that correspond to lower and upper flow limits. ...

Distributed balancing under interval flow constraints in directed communication topologies
Hadjicostis, Christoforos N.; Domínguez-Garcia, A. D. (Institute of Electrical and Electronics Engineers Inc., 2018)In this paper, we propose a distributed algorithm that relies on a strongly connected (but possibly directed) communication topology to achieve admissible and balanced flows in a given network. More specifically, we consider ...

Distributed frequency control of inertia-less AC microgrids
Cady, S. T.; Hadjicostis, Christoforos N.; Domínguez-Garcia, A. D. (Institute of Electrical and Electronics Engineers Inc., 2015)In this paper, we introduce a generation control architecture for microgrids that ensures stable and synchronized operation at a specific frequency. We also propose a distributed implementation of this architecture that ...

A Distributed Frequency Regulation Architecture for Islanded Inertialess AC Microgrids
Cady, S. T.; Zholbaryssov, M.; Domínguez-Garcia, A. D.; Hadjicostis, Christoforos N. (2017)We address the problem of frequency regulation in islanded ac microgrids with no inertia, i.e., those consisting entirely of generators interfaced through power electronics. The control architecture we propose to achieve ...

A distributed generation control architecture for islanded ac microgrids
Cady, S. T.; Domínguez-Garcia, A. D.; Hadjicostis, Christoforos N. (2015)In this paper, we propose a distributed architecture for generation control in islanded ac microgrids with both synchronous generators and inverter-interfaced power supplies. Although they are smaller and have lower ratings, ...

Distributed matrix scaling and application to average consensus in directed graphs
Domínguez-Garcia, A. D.; Hadjicostis, Christoforos N. (2013)We propose a class of distributed iterative algorithms that enable the asymptotic scaling of a primitive column stochastic matrix, with a given sparsity structure, to a doubly stochastic form. We also demonstrate the ...

Distributed resource coordination in networked systems described by digraphs
Domínguez-Garcia, A. D.; Hadjicostis, Christoforos N. (2015)We consider a multicomponent system in which each component can receive/transmit information from/to components in its immediate neighborhood. Communication links between components are not required to be bidirectional, ...

Distributed strategies for average consensus in directed graphs
Domínguez-Garcia, A. D.; Hadjicostis, Christoforos N. (2011)We address the average consensus problem for a distributed system whose components (nodes) can exchange information via interconnections (links) that form an arbitrary, strongly connected but possibly directed, topology ...

Finite-time approximate consensus and its application to distributed frequency regulation in islanded AC microgrids
Cady, S. T.; Domínguez-Garcia, A. D.; Hadjicostis, Christoforos N. (IEEE Computer Society, 2015)In this paper, we propose an iterative algorithm that allows a set of interconnected nodes to reach approximate consensus in a finite number of steps, i.e., Allows the nodes to reach agreement to within a pre-specified ...
