Active Distribution Networks, Interconnected Microgrids, and Energy Hubs
As microgrids continue to grow as an important topic in the power and energy industry, it becomes more and more imperative for all engineers and researchers in the field to be familiar with the many aspects of microgrids. In particular, Microgrid interconnectivity, active distribution networks, energy hubs, and the ways that all of these technologies support microgrids proves to be a necessity for anyone in the power and energy industry to understand.
To help our members keep up with the latest and best thinking in this topic, IEEE Power & Energy Society has created a number of resources on this subject. This email is intended to highlight a few of those resources, as well as upcoming events and content focused on this subject:

PES-TR-66: Microgrid Stability Definitions, Analysis, and Modeling
This document defines concepts and identifies relevant issues related to stability in microgrids. It proposes a definition and a classification of microgrid stability, taking into account pertinent microgrid features such as voltage-frequency dependency, unbalancing, low inertia, and generation intermittency. The modeling of microgrid components such as generators, converters, distribution lines, loads, and distributed energy resources for stability analysis is discussed in detail. Analysis techniques and tools relevant to microgrid stability are also reviewed, as well as various examples highlighting some of the stability classes defined in this report.
Microgrid Stability Definitions, Analysis, and Examples
This document is a summary of a report prepared by the IEEE PES Task Force (TF) on Microgrid Stability Definitions, Analysis, and Modeling, IEEE Power and Energy Society, Piscataway, NJ, USA, Tech. Rep. PES-TR66, Apr. 2018, which defines concepts and identifies relevant issues related to stability in microgrids. In this paper, definitions and classification of microgrid stability are presented and discussed, considering pertinent microgrid features such as voltage-frequency dependence, unbalancing, low inertia, and generation intermittency. A few examples are also presented, highlighting some of the stability classes defined in this paper. Further examples, along with discussions on microgrid components modeling and stability analysis tools can be found in the TF report.
PES-TR22: Contribution to Bulk System Control and Stability by Distributed Energy Resources Connected at Distribution Network
The penetration of Distributed Energy Resources (DER) within the Distribution Network DN increases worldwide. This report outlines how DER can contribute to the bulk system control and the overall stability of a power system when connected to the distribution network.
Trends in Microgrid Control
The increasing interest in integrating intermittent renewable energy sources into microgrids presents major challenges from the viewpoints of reliable operation and control. In this paper, the major issues and challenges in microgrid control are discussed, and a review of state-of-the-art control strategies and trends is presented; a general overview of the main control principles (e.g., droop control, model predictive control, multi-agent systems) is also included. The paper classifies microgrid control strategies into three levels: primary, secondary, and tertiary, where primary and secondary levels are associated with the operation of the microgrid itself, and tertiary level pertains to the coordinated operation of the microgrid and the host grid. Each control level is discussed in detail in view of the relevant existing technical literature.
