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 Speakers: Julia Matevosyan, Lead Planning Engineer, ERCOT Jason MacDowell, Senior Director – Technology, Strategy & Policy, GE Power Webinar Abstract: Grid-Forming technology is viewed as one of the necessary enablers for high penetration of inverter based resources. While it continues to be an area of active research, grid-forming battery energy storage systems are already commercially available and are being used in an number of applications around the world (e.g. US, Australia, and a number of Island applications). This webinar will provide an overview of existing and ongoing projects, focusing on the drivers behind the choice of technology and project performance. The webinar is based on the whitepaper “The Role of Grid Forming Technology to Enable Energy Systems Integration” on which the ESIG High Share of Inverter-Based Resources Task Force is currently working.

Featured Speakers: Dr. Karl Hausker, Senior Fellow, World Resources Institute Dr. Karen Palmer, Senior Fellow and Director of the Future Power Initiative, Resources for the Future Steve Corneli, Principal and Owner, Strategies for Clean Energy Innovation Webinar Abstract: Policymakers in the U.S. and many other countries are examining whether current electricity market designs are well-suited to support the efficient and rapid decarbonization of the power sector. WRI and RFF are exploring concepts for organized long-term markets designed to operate parallel to today’s short-term energy markets, and intended to identify and support the financing and development of efficient, reliable mixes of clean (i.e., zero- and very low-carbon) resources. Karl Hausker and Karen Palmer will present on why such markets may be needed, and on four potential long-term market designs.

The EERA Joint Program on Energy Systems Integration together with ESIG, is organizing a workshop program on the issue of “System Integration Costs”. In the last decade, a diversity of publications, reports and approaches have been presented on this matter, with sometimes seemingly different interpretations. This webinar is part of a four-step program on this matter (including also an in-person workshop in fall 2021 in Leuven, Belgium, and the writing of a consensus paper). Through this program, we will strive for a common understanding and consensus of this concept. Featured Speakers: The Hirth & Ueckerdt Philosophy of System Value and System Cost Lion Hirth (Neon Energy & Hertie School, Berlin, DE) & Falko Ueckerdt (Potsdam Institute, DE) The Milligan School on Cost Causation Juha Kiviluoma (VTT, FI) The NEA Approach Confronting VRE with Nuclear Marco Cometto (formerly OECD/NEA, now IAEA, Vienna, AT) & Jan Horst Keppler (OECD/NEA & Univ Dauphine, Paris, FR) The System Cost Detailed Simulation Approach Goran Strbac (Imperial College, London, UK) Moderators: William D’haeseleer (KU Leuven, BE) and Erik Delarue (KU Leuven, BE)

Featured Speakers: Farina Farrier, Head of Open Networks, Energy Networks Association; Randolph Brazier, Director, Innovation & Electricity Systems, Energy Networks Association Webinar Abstract: Launched in 2017, ENA’s Open Networks Project is laying the foundations of a smart, flexible energy system in Great Britain. Through the work over the years, the project has introduced real momentum into the transition to Distribution System Operation and is playing a key role in enabling local markets for flexibility. With over 2.9GW of flexibility planned for tender by Distribution networks in 2021 in Great Britain, the Open Networks Project is playing a key role in boosting flexibility markets and enabling DER to participate in them.

Featured Speaker: Tim Green, Professor, Co-Director of the Energy Futures Laboratory (EFL), Imperial College London Webinar Abstract: The replacement of electro-mechanical machines by inverter-based resources (IBR) is fundamentally changing the dynamics and stability properties of grids. A review will be made of the needs a grid system has in order that it is stable and secure. The needs in terms of voltage strength, frequency regulation and synchronisation will be discussed in term of how they are met by synchronous machines, grid-following converters and grid-forming converters. A case will be made that there is advantage in not all resources being obliged to provide all system services and that new services can replace some traditional services. Thus, strictly following a virtual synchronous machine (VSM) approach may not yield the best solution. Approaches to ensuring system-wide dynamic stability will also be explored noting that IBR have overlapping sets of dynamics but with details often hidden in black-box models. A method for identifying root-causes of poorly damped modes in black-box models will be illustrated. This analytical grey-box method avoids exhaustive transient simulation. A toolbox for compiling models of composite grids with IBR and synchronous machines will be introduced. The talk will conclude with some thoughts on modelling and analysis challenges that remain for IBR dominated grids.
