1Resilient Networked Control of Distributed Energy Resources

This paper considers networked systems and develops a class of distributed algorithms that are resilient against potential packet drops in the communication links between system components. We apply this class of algorithms to the problem of coordinating distributed energy resources (DERs) for service provision to the grid they are connected to, e.g., reactive power support for voltage control. In this problem, each system component can contribute a certain amount of active and/or reactive power, bounded from above and (possibly) below by capacity constraints, and the objective is to coordinate the components so as to collectively provide a predetermined total amount of active and/or reactive power. In the class of algorithms proposed to address this problem, each DER maintains a set of variables and updates them through information exchange with neighboring DERs. We show that, as long as the underlying graph that describes the information exchange between components is strongly connected, and the predetermined total amount of active and/or reactive power does not violate (upper or lower) total capacity constraints, DERs can use this approach to calculate, in a distributed fashion, their fair contribution (subject to their capacity constraints). We show that algorithms reach almost surel
