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.

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

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.

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.
