Featured Speaker: Christian Frank Flytkjær, Senior Manager, Grid Analysis, Energinet

Webinar Abstract: To harvest wind energy efficiently, Denmark is constructing two energy islands. The energy islands will serve as offshore hubs, collecting and transmitting wind energy to Denmark and other European countries by several interconnectors installed on the hub. At a later stage, PtX-plants will be installed reducing transmission capacity needs. The ambition is to construct one 3 GW island in the North Sea expandable to 10 GW and one in the Baltic Sea as well. Both can be considered 100% inverter-based power systems designed from a blank sheet of paper. This presentation will cover the power system design considerations and technologies enabling the hubs.


Transforming the Grid: Personal Experiences

October 20, 2021 – 3:00 p.m. – 4:30 p.m. GMT – Virtual via WebEx Events

What happens when a country commits to a nationally determined contribution (NDC), but the country’s grid system operator is not confident it can meet those goals while maintaining grid system reliability? In this session, attendees will meet system operators who have said “yes” to this challenge and are now bending the limits of what was previously thought possible with high penetration and renewable energy grid operation.

In addition to system operators, engineers on the cutting-edge of making progress in this area will share stories and insights of how they have achieved record breaking instantaneous renewable penetration in large grids and conceptualized their outlook on what the next steps are to achieve grids that are reliably stable under 100% renewable energy conditions. Further, system operators from countries at earlier stages of renewable energy integration will join to share their plans regarding what interventions they are taking now to avoid locking in emissions from additional fossil fuel-based generators, and instead put them in a position to create high penetration renewable energy grids in the future.

This session is targeted at policy makers and accessible to individuals of all levels of technical background. By bringing in experts from system operators in conversation with a top policy expert, the session will elicit precise technical discussions coupled with clear explanations. Further, by using the lens of individual stories, the session will humanize technical topics and share the triumphs, setbacks, and excitement of one of the greatest technical endeavors of our times.

Pillar 5 Webinar: Building an Open-Source Strategy at Power Grid Operators

October 27, 2021 – 11:00 AM EDT – Virtual via Zoom

This is the first event of a joint webinar series from the G-PST Consortium and LF Energy, where the emerging role of open source software at system operators will be examined. This event will focus on the reasons that power system operators may want to adopt an open source strategy and migrate their activities to open source tools. Industry leading panelists will share their experiences regarding adopting an open source strategy.

Panelists include:

  • Lucian Balea, RTE
  • Shuli Goodman, LF Energy
  • Antonio Monti, ETH Zurich
  • Jesper Nielsen, Energinet
  • Arjan Stam, Alliander


November 10, 2021 – 4:00 PM EST – Virtual via WebEx Events

Featured Speaker: Sebastian Achilles, Managing Director Power Systems Operation and Planning, GE Energy Consulting

Webinar Abstract: Operation of Inverter Based Resources (IBR) in weak grid conditions is a relatively old subject that does not seem to go away. The webinar will begin with a short introduction on the types of performance issues associated with weak grid and related mitigations used in the industry. We will then elaborate on how the weak grid operation challenges have changed in recent years due to the large deployment of IBR, and aspects of grid code requirements that affect the risk of weak grid related issues in the lifetime of IBR plants. The speaker will also share observations on study, modeling and short circuit ratio (SCR) screening aspects based on recent experiences, with a focus on what seems to be changing from prior practices. The discussion will elaborate on grid following (GFL) and grid forming (GFM) IBR resources in the context of weak grids, and why GFM may help, but not necessarily solve, all weak grid risks. The talk will be presented from an OEM perspective.


Accelerating Power System Transformation through Technical Innovation and Global Partnership
8th November 2021 – 12:00 – 13:30 GMT – Hybrid event hosted in partnership with Accenture

Deep decarbonisation of the power sector is one of the most important levers for tackling climate change and setting a credible path to reaching net-zero. However, there are many technical and operational challenges associated with operating a zero-carbon electricity grid, much of which will be powered by variable renewable energy. Overcoming these barriers and building new capabilities, both in developed and developing countries, will be critical in accelerating the transformation to a low emission, low cost, secure, and reliable power system. Join us at COP26, in person or virtually, as we outline the role of technology, innovation and ecosystem partnerships in overcoming these barriers

2021: U.S. Secretary of Energy and U.K. Secretary of State of Business, Energy, and Industrial Strategy (BEIS) Join CEOs and Energy Leaders to Launch the Global Power System Transformation (G-PST) Consortium during U.S. Climate Action Week

The G-PST Consortium hosted its formal launch event on April 21st at 8 a.m. US EDT, convened in association with US Climate Action Week. U.S. Secretary of Energy Jennifer Granholm and U.K. BEIS Secretary of State Kwasi Kwarteng, together with several executives of power system operators and institutions from around the world, officially launched the G-PST Consortium. The event also showcased the G-PST Consortium’s inaugural research and teaching agendas.

2020: World’s Leading Power System Operators Announce Global Consortium

Earlier today during the BloombergNEF Summit, Audrey Zibelman, CEO of the Australia Energy Market Operator (AEMO) announced the launch of the Global Power System Transformation Consortium (G-PST). Speaking during the European Energy Infrastructure in Transition Session, Zibelman highlighted the need for a major global collaborative effort in overcoming technical barriers related to the integration of clean energy into power systems at an unprecedented scope and scale.
