Abstract: A microgrid is defined as a group of Distributed Energy Resources (DERs) and loads that act locally as a single controllable entity and can operate in both grid-connected and islanded modes. Microgrids are considered a critical link in the evolution from vertically integrated bulk power systems to smart decentralized networks, by facilitating the integration of DERs. Entities, such as government agencies, utilities, military bases, and universities around the world are deploying microgrids, and an increasing number of these systems are expected to be developed in the next decade. In general, stability in microgrids has been treated from the perspective of conventional bulk power systems. However, the nature of the stability problem and dynamic performance of a microgrid are considerably different than those of a conventional power system due to intrinsic differences between microgrids and bulk power systems, such as size, feeder types, high share of Renewable Energy Sources (RES), converter-interfaced components, low inertia, measurement devices such as Phase-Locked Loop (PLL), unbalanced operation, etc.

This seminar discusses the findings of the award-winning IEEE PES Task Force on Microgrid Stability Definitions, Analysis, and Modeling, which defines concepts and identifies relevant issues related to stability in microgrids. The seminar presents definitions and classification of microgrid stability, considering pertinent microgrid features such as voltage-frequency dependence, unbalancing, low inertia, and generation intermittency. A few examples will be also presented, highlighting some of the stability classes discussed during the seminar.
