Toward 100% Renewable Energy Pathways: Key Research Needs (PDF)

On May 14 and 15, 2019, the ESIG held a workshop bringing together 56 experts from around the globe to identify the technological and economic integration challenges of transforming the electricity system toward 100% renewable. This report summarizes the outcome of the meeting. The workshop summarized in the report is seen as the first step of many to address the issue of going toward 100%, with the ultimate aim of producing a research roadmap for use by researchers, research organizations, and funders to help focus and prioritize their efforts and investments.

Tools & Data

RE Data Explorer

In collaboration with the G-PST Consortium, USAID and NREL have developed an open data platform, called RE Data Explorer, that provides publicly available high temporal and spatial resolution renewable energy data for many countries around the world. As an exciting development, a data upgrade is underway for Southeast Asia that will allow visitors to visualize and download solar resource data at 10-minute intervals across a 2-km grid covering the entire region. These and other datasets within the RE Data Explorer can support system operators and other decision-makers in planning for power system transformation and deploying higher shares of renewables onto the grid.


G-PST/ESIG Webinar Series: Survey of Grid-Forming Inverter Applications

9 June 2021 | Online via WebEx

Featured Speaker: Julia Matevosyan, Lead Planning Engineer, ERCOT

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.

Pillar 5 Webinar: Open Source Tools for System Operators – Focus on Power Flow Tools

27 May 2021 | Online via WebEx

The rise of data science and scientific programming languages, such as Python and Julia, presents numerous opportunities for power system modernization and advanced analytics. In recent years, the quality and availability of open-source power systems analysis tools in these languages has dramatically increased. However, despite widespread usage of open languages for data analysis, industrial usage of open power systems analysis tools remains rare. The G-PST Consortium’s Pillar 5 lead organization, VTT Technical Research Centre of Finland, present a webinar series that will showcase some of the most capable power systems analysis and modeling tools that exist within common data science languages to highlight opportunities to enable advanced analytic workflows. This first installment focuses on workflows in Python, using the popular data analysis package, Pandas, and the power systems analysis package, PandaPower. Contributors to the event include:

  • Hannele Holttinen – Pillar 5 Lead, VTT Technical Research Centre of Finland
  • Juha Kiviluoma – Pillar 5 Lead, VTT Technical Research Centre of Finland
  • Dheepak Krishnamurthy – Distribution Systems Researcher, NREL
  • Clayton Barrows – Senior Engineer, NREL
  • Roman Bolgaryn – Researcher, Fraunhofer IEE
  • Friederike Wenderoth – Researcher, Fraunhofer IEE

G-PST/ESIG Webinar Series: Is “Grid Forming” Enough: What Do Electricity Grids Need From IBR?

12 May 2021 | Online via WebEx

Featured Speaker: Tim Green, Professor, Co-Director of the Energy Futures Laboratory (EFL), Imperial College London

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.

Pillar 4 Webinar: Impact of Inverter Based Generation on Bulk Power System Dynamics and Short-Circuit Performance

27 April 2021 | Online via WebEx

Featured Speakers: Gary Kobet, Tennessee Valley Authority and Pouyan Pourbeik, PEACE®.

Electric power systems around the world are undergoing a historic change in their generation mix, from synchronous ac rotating machines to inverter-based resources, which are power-electronic based technologies. Conventional planning and operating practices are adapting to the benefits and challenges these resources bring to reliability of the bulk power system (BPS). One issue that is increasingly becoming apparent under higher penetrations of inverter-based resources such as wind and solar photovoltaic (PV) generation, is a reduction in fault currents and short circuit strength.

This webinar explores some of the technical challenges and opportunities presented by this transformation of the grid, as has been presented in the IEEE Technical Report PES-TR68, Impact of Inverter Based Generation on Bulk Power System Dynamics and Short-Circuit Performance, July 2018, and goes a little beyond by briefly also touching on the latest developments in the industry and how some of the issues and gaps identified in the IEEE PES-TR68 are being addressed by industry efforts that have started since that time.
