The rapid interconnection of bulk power system (BPS)-connected inverter-based resources (IBR) is fundamentally transforming the electric grid both in Texas and throughout North America. The transformation of the power system from one dominated by large spinning masses to variable resources operated by power electronics, along with the increased use and importance of natural gas resources for system balancing and the participation of distributed energy resources (DER), is occurring rapidly. Although inverter technology and distributed resources each promise significant benefits, the speed of this change continues to challenge regulators, grid planners, operators, cybersecurity professionals, engineers, and inverter manufacturers, among others. These challenges are evidenced by several events, both in Texas and elsewhere, that make plain the reliability challenges posed by this foundational and swift transformation.
In light of these changes, Texas RE held a special Grid Transformation Workshop on July 20, 2023, to explore the multifaceted aspects of navigating this transition and realize the benefits of an ever-increasing inverter-based grid topology. The workshop brought together a broad set of energy industry experts to discuss the issues in planning for, modeling, and reliably implementing our evolving grid. The workshop focused particularly on the challenges in commissioning IBRs and DERs, effectively modeling their behavior, ensuring they are adequately secured, and that they perform as needed to maintain reliability.

Characterizing renewables and IBRs has proven challenging for traditional planning methods as advanced models and tools are needed to study their dynamic behavior. The variability of renewable generation and the potential of energy storage, aggregated distributed energy resources, and large flexible demand response must also be factored into grid studies, along with continued use of conventional generation. This panel will explore how planning for the transitioning grid is itself part of the changes.
As DER technologies continue to evolve and become increasingly interconnected locally and to the power grid, it is critical to ensure strong cybersecurity controls are considered when designing and implementing associated devices, systems, and infrastructure. It has become vital that all levels of the energy sector industry collaborate to address cybersecurity challenges to mitigate emerging cyber risks.
Industry-leading cybersecurity experts will share their knowledge, opinions, and experiences on implementing cybersecurity standards and best practices for associated information technology (IT) and operations technology (OT) systems. This panel will cover themes such as security by design, system hardening, industrial internet of things, cloud services, virtualization, data and communication protection, and supply chain.
Jimmy Glotfelty – Public Utility Commission of Texas (PUCT)
Detailed reports about disturbances in Texas and California involving a widespread reduction of solar photovoltaic (PV) resource power have strong recommendations based on the conditions experienced during the events. With the recent and expected increases of utility-scale IBRs, the causes of a sudden reduction in power output from these resources needs to be widely communicated and addressed by the industry. One key point in the Texas and California reports identified that inverter-based resources (with emphasis on solar PV plants) lack sufficient ride-through capability to support the BPS for normal BPS fault events. This reliability concern is persistent and growing in the number of resources prone to this issue, while mitigation appears to be lagging or varied and warrants understanding. This panel of experts will discuss various complex aspects of IBR performance in the industry today.
Considering the resource mix that is being built within the Texas Interconnection, the panel will discuss bottlenecks for new entities in the ERCOT process as well as challenges faced in obtaining the necessary schedules, models, and commissioning. Developers will provide insight on difficulties with supply chain and procurement. The conversation will also touch on commissioning and interconnection activity outside the ERCOT Region to see what best practices are in place as well as cover changes contemplated within ERCOT and state rules.
