Energy Systems Integration Group

The Energy Systems Integration Group (ESIG), previously known as the Utility Wind Integration Group (UWIG), was established in 1989 to provide a forum for the critical analysis of wind for utility applications. Initially focused on wind power, UWIG expanded its focus to include solar power and distributed generation and become known as the Utility Variable-Generation Integration Group in 2011. In 2018, driven by the economics and growth of renewable energy and the interdependent nature of the global energy industry, the association expanded its focus beyond the electricity system of today. These expanding perspectives around energy, and the growing need for coordination across the ways that we produce, convert, deliver and use energy, are the reasons we have become the Energy Systems Integration Group (ESIG).

Featured Speaker: Shahil Shah, Senior Engineer, NREL About the Webinar: Dynamic stability is a major concern in operating power systems with high levels of inverter-based resources (IBRs). Dynamic stability problems in IBR grids manifest as oscillations or control interactions that are observed either locally between a few IBRs or span a wider network involving tens to hundreds of IBRs. It is quite challenging to evaluate the stability of IBR grids because of fast, complex, and non-standardized controls of IBRs as well as unavailability of their open-box models from vendors. This webinar will review impedance-based methods for stability analysis of IBR grids. It will also present a PSCAD-based impedance scan software tool and an impedance measurement system developed at NREL for analyzing the stability of IBR grids. Case studies to demonstrate the capabilities of these tools to answer questions such as “which IBRs are causing oscillations?” or “how much grid-forming capacity is needed in a system?” will be presented.

Featured Speakers: Joe Rand, Lawrence Berkeley National Laboratory; Aaron Bloom, NextEra Analytics; Kalyan Chilukuri, Electric Power Engineers; Johannes Pfeifenberger, The Brattle Group; Aaron Vander Vorst, Enel Green Power About the Webinar: ESIG and LBNL are jointly launching a webinar series on reform of generator interconnection processes in the bulk power system. This builds on the Generator Interconnection panel session from ESIG’s Spring Workshop in March and LBNL’s body of research on interconnection queues across the US. Participants will discuss: 1) the proposed creation of a new ESIG/LBNL joint effort on generator interconnection, and 2) study criteria used by U.S. independent system operators in evaluating new generator additions. Attendees will have an opportunity to voice their opinion on topics that this joint effort should explore and learn about differences in interconnection study criteria between the U.S. Independent System Operators. The panel will conclude with a discussion of the implications of interconnection study criteria on network upgrades and system planning.
