Abstract

Autonomous microgrids with a cluster of conventional rotating synchronous machines, electronically interfaced distributed resources, and energy storage systems can have complex dynamic characteristics. An eigenanalysis-based small signal stability evaluation technique is developed in this paper to study the dynamic stability of such microgrids. To this end, the small signal models of each subsystem of a microgrid is developed and then merged together within a common reference frame to determine its stability margins. Then, a sensitivity analysis is performed to identify the trend in the change of the stability margins with respect to the variations in the number and capacities of its inertial and non-inertial distributed energy resources.
