This webinar will discuss the problem of frequency regulation in islanded ac microgrids with no inertia, i.e., those consisting entirely of generators interfaced through power electronics. The control architecture we propose to achieve this is designed to drive the average frequency error to zero while ensuring that the frequency at every bus is equal and that the operating point that results is stable.
We also introduce a distributed implementation of the proposed control architecture that relies on a combination of several distributed algorithms. Two of the algorithms, which are well-established consensus-type algorithms, allow the generators and loads to acquire global information needed for making control decisions; the third algorithm, which we propose herein, enables the generators to obtain output values that balance the total demand for load without violating line flow constraints.
Collectively, these algorithms eliminate the need for a centralized entity with complete knowledge of the network, its topology, or the capabilities or properties of the generators and loads therein. Moreover, the distributed implementation we propose relies on minimal measurements, requiring only that the power injection at each bus be measured.

The webinar begins with a discussion of key industry/societal trends. The “smarter grid” highlights the intelligence that has already been implemented, and the new intelligence being added to the grid today. The Smart Grid technology roadmap provides examples of six Smart Grid solutions being deployed today. The importance of integration of technology components is emphasized, and its impact on grid resiliency.
The 16 Smart Grid foundational industry standards are critical for effective integration of technology components and successful interoperability. Interoperability requires communications between technology components (i.e., utilizing communications protocols) and effective exchange of information between technology components. Emerging technologies in microgrids and distributed generation include voltage regulation equipment, grid edge controllers and smart inverters. One impact of high penetration of rooftop solar PV on the distribution system is three new applications of power electronics.
Lessons learned in microgrids and distributed generation are discussed, which include impediments to be addressed and enablers for success. The IEEE Power & Energy Society (PES) input to the DOE for the Quadrennial Energy Review (QER) on the vision for microgrids and distribution generation is summarized, including technology, standards, policy and the business case.

Numerous drivers are causing the amount of distributed generation being deployed on distribution systems to increase dramatically in many parts of the world.
This webinar will present a range of issues that must be considered on the distribution system when high penetrations of distributed energy resources (DER) are already present or expected. Methodologies for prioritizing which substations and feeders are candidates for new investment to support high penetration DER are presented.
Some existing technologies for volt/var management such as mechanically switched capacitors and load tap changers are challenged in a highly variable generation environment – alternatives will be discussed.
References to key documents and guidelines on supporting this challenge from DOE, EPRI, the SGIP and others will be provided.
