title = "Assessing the Impact of Achieving Optimal Economic Dispatch on Delay Margin of Distributed Secondary Control",
abstract = "The incremental cost (IC) has been equalized through means of distributed control in the literature to achieve optimal generation. Yet, the IC can be linear or nonlinear depending on the cost characteristics of the distributed generators (DG). Unstable microgrids can occur due to communication delays when distributed control is utilized. Prior research has examined the impact of communication delays and has determined the specific delay at which the system experiences instability. This paper analyzes the effect of nonlinear IC on the delay margin. A small-signal model has been created that contains IC equalizing and frequency restoration secondary controllers. Communication delays in the links have been taken into account within the constructed model. It has been concluded the delay margin differs from one loading condition to another, and the reliability is, accordingly, impacted.",
