Transforming the Grid: Personal Experiences

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 heard from 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 also heard 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 shared 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. By using the lens of individual stories, the session humanizes technical topics and share the triumphs, setbacks, and excitement of one of the greatest technical endeavors of our times.

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.

G-PST Hosts System Operator Leadership Forum

To support the visionary goal of the G-PST Consortium to reduce power sector emissions by 50% globally by 2030, there is a need to build confidence within system operators at the highest level that reaching high variable renewable energy (VRE) penetration, while ensuring system reliability, is possible. To develop this confidence among system operators initiating the energy transition, the G-PST Consortium hosted a virtual joint forum on October 4th, 2021 between the leadership of emerging economy system operators and those from the G-PST’s founding system operators (FSOs). These FSOs represent grid systems that are at the cutting-edge of the energy transition and regularly manage reliability under high VRE penetration.

This forum provided a space for the FSOs to share their journeys, including key challenges, solutions, and good practices, as they have moved to high VRE penetration. It was also facilitated by Rebecca Collyer of the European Climate Fund to encourage open dialogue in a small group setting to encourage honest and frank sharing of challenges, as well as knowledge and solutions, to build confidence at the highest levels within system operators globally, while also setting the stage for future peer learning and technical discussions between staff within the system operators.

Southeast Asia Community of Practice: Tools and Case Studies for Inertia Monitoring and Calculation

System inertia has long been used by system operators to keep the frequency of the system from straying too far from normal. Historically, inertia from traditional sources (i.e., the spinning mass of generators and motor loads) were abundant and it was not necessary to monitor the amount of online inertia at any one time. But as the role of inverter-based resources (i.e., wind, solar, and battery storage) increases, inertia from traditional sources is decreasing. System operators globally have found it to be valuable to estimate and monitor the online inertia to ensure the system will respond adequately to sudden changes in frequency, even though inertia is not the only option to arrest frequency deviations. This webinar explores the diversity of methods used by system operators in Southeast Asia and globally to track inertia, giving more confidence to operators in the control room that a system in transition can operate as securely as systems of the past.

Impact of Inverter Based Generation on Bulk Power System Dynamics and Short-Circuit Performance

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.
