The aim of COP26 is to unite parties with a role to play in accelerating collective progress towards the goals of the Paris Agreement and the United Nations Framework Convention on Climate Change. The G-PST Consortium is honored to be participating in both in-person and virtual sessions. Learn more about the G-PST Consortium’s events below.

Transforming the Grid: Personal Experiences

20th October 2021 – 3:00 – 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.

Attendees will hear about solutions these leading system operators are using to manage grid frequency and strength, how they 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. System operators from countries at earlier stages of renewable energy integration will join to share their plans regarding what interventions they are taking 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 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.

Accelerating Power System Transformation through Technical Innovation and Global Partnership

8th November 2021 – 12:00 – 1:30 p.m. GMT
Hybrid event – Hosted in partnership with Accenture

Deep decarbonization 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. The G-PST Consortium and Accenture are co-hosting this event which will outline the role of technology, innovation, and ecosystem partnerships in overcoming these barriers. This is a hybrid event where attendees may join in person or online. Registration is hosted through Accenture.

G-PST/ESIG Webinar Series: Connect Faster: Improving Renewable Energy Integration With Modular Power Flow Control

Featured Speaker: Michael Walsh, Chief Commercial Officer, Smart Wires

Modular power flow control provides a uniquely effective approach to help renewable generation developers and asset owners address their most challenging transmission needs. The modern, power-electronics-based version of these devices, built upon decades of grid experience, helps balance network flows by pulling or pushing power through capacitive or inductive voltage injection. When new generation seeks grid interconnection, it routinely requires network upgrades to enable firm export of power. Under business-as-usual transmission planning strategies, these upgrades can be extensive because much of the grid was not designed for distributed, intermittent, renewable generation. Reconductors, substation refurbishments or new lines are all costly, traditional solutions that can take many years to complete due to permitting and other challenges. Yet significant latent capacity exists in most networks around the world, a recent study by the Brattle Group highlights how this technology can dramatically improve the scale of renewable generation integration in the Southwest Power Pool network. Modular power flow control has proven to help utilities plan and operate their grid to leverage this capacity, enabling new generation to be connected must faster and more cost-effectively – supporting regulatory targets while benefiting ratepayers and developers alike. In a recent deployment with National Grid Electric Transmission in the UK, modular power flow control enabled 1.5 GW of renewable generation to access the London metro area by increasing utilization of the existing transmission capacity. Solutions like this one allow rapid deployment scaling, in line with phased generation connection, further reducing upfront capital burden on developers. These standard offerings can generally be installed in 1 year or less, alleviating thermal overload-induced congestion to improve the financial feasibility of previously uneconomic renewable energy projects.

New Focused Research Team Launched

To increase the impact of its activities, the RAG developed several focused research teams with the aim of providing some fundamental underpinnings to the more detailed research questions in the research agenda, which should ensure meaningful research findings and applications in the longer term. These teams are made up of subject matter experts from the FSOs and leading researchers from the Core Team of the G-PST.

The Inverter-based Resources Research Team: This team investigates how the fundamental needs of the power system can be supplied (as a service) by Inverter-Based Resources (IBRs) and where additional research will be needed to access these capabilities. This team also addresses how the tools and models we currently use to study the power system will need to be updated (or superseded) in light of the grid’s changing nature with increasing IBRs. The IBR Research Team is working as part of the ESIG, High Share of Inverter-Based Generation Task Force.

The ESIG Redefining Resource Adequacy Task Force: This task force hosts the G-PST Resource Adequacy Research Team. This research team is investigating how the rise of variable, energy limited resources combined with severe weather events will require changes to planning practices to ensure low-cost reliable power systems of the future.

In addition to these research teams there is also an extensive Research Repository being developed.  It details current and recent research projects from around the world that are well-aligned with the Inaugural Research Agenda. This repository can be used by funding and research institutions to ensure they are up-to-date with the latest research and not duplicating efforts. Well-aligned projects may also receive support from the FSOs in terms of input and demonstration opportunities.
