Fluctuations in renewable generation motivate a need for real-time coordination of distributed energy resources (DERs) such as demand response resources. Dynamic real-time market mechanisms are a promising approach to facilitate coordination of DERs. However, the implementation of such mechanisms over a large geographic region requires communication across networks which can introduce non-negligible latency, congestion, and packet loss. Such network disruptions raise questions regarding grid resilience, especially, when combined with physical outages. In this paper, we propose a framework for evaluating the resilience of dynamic real-time market mechanisms under a variety of network scenarios that are indicative of real-time implementation challenges. We develop a non-dimensional metric, which takes into account the impact of a physical contingency, and can be used to evaluate the ability of a dynamic market mechanism to adapt to and recover from this contingency. We evaluate the resilience of a recently proposed dynamic real-time market mechanism on the IEEE 118-bus system following a single generator outage in the presence of communication outages.
