Summary: This project will outline and address specific challenges in developing distributed control solutions for islanded lossy microgrids, focusing primarily on the power-sharing problem. Challenges are anticipated given the non-convex three-phase power system models, the need to build distributed secondary controls around fast droop-based local controls, and the constrained and noisy nature of communication channels. Thus, although there is a significant literature on distributed control systems and even their applications to power systems, we expect that new distributed control architectures will be needed for islanded microgrids, which take into account practical considerations regarding distribution-system models (e.g. network losses), legacy controls, and failure-prone communications. We anticipate that these algorithms may draw on recently-developed concepts for input-output dynamic analysis and sparse controller design for linear and nonlinear networks, which were developed in the controls-engineering community.
