Advanced Transmission Technologies
Advanced Transmission Technologies December 2020 United States Department of Energy Washington, DC 20585 Executive Summary The high-voltage transmission electric grid is a complex, interconnected, and interdependent system that is responsible for providing safe, reliable, and cost-effective electricity to customers. In the United States, the transmission system is comprised of three distinct power grids, or “interconnections”: the Eastern Interconnection, the Western Interconnection, and a smaller grid containing most of Texas. The three systems have weak ties between them to act as power transfers, but they largely rely on independent systems to remain stable and reliable. Along with aged assets, primarily from the 1960s and 1970s, the electric power system is evolving, from consisting of predominantly reliable, dependable, and variable-output generation sources (e.g., coal, natural gas, and hydroelectric) to increasing percentages of climate- and weather- dependent intermittent power generation sources (e.g., wind and solar). All of these generation sources rely heavily on high-voltage transmission lines, substations, and the distribution grid to bring electric power to the customers. The original vertically-integrated system design was simple, following the path of generation to transmission to distribution to customer. The centralized control paradigm in which generation is dispatched to serve variable customer demands is being challenged with greater deployment of distributed energy resources (at both the transmission and distribution level), which may not follow the traditional path mentioned above. This means an electricity customer today could be a generation source tomorrow if wind or solar assets were on their privately-owned property. The fact that customers can now be power sources means that they do not have to wholly rely on their utility to serve their needs and they could sell power back to the utility. -

Small Vulnerable Sets Determine Large Network Cascades in Power Grids
Article Summary — followed by the full article on p. 4 Small vulnerable sets determine large network cascades in power grids Yang Yang,1 Takashi Nishikawa,1;2;∗ Adilson E. Motter1;2 Science 358, eaan3184 (2017), DOI: 10.1126/science.aan3184 Animated summary: http://youtu.be/c9n0vQuS2O4 1Department of Physics and Astronomy, Northwestern University, Evanston, IL 60208, USA 2Northwestern Institute on Complex Systems, Northwestern University, Evanston, IL 60208, USA ∗Corresponding author. E-mail: [email protected] Cascading failures in power grids are inherently network processes, inwhich an initially small perturbation leads to a sequence of failures that spread through the connections between sys- tem components. An unresolved problem in preventing major blackouts has been to distinguish disturbances that cause large cascades from seemingly identical ones that have only mild ef- fects. Modeling and analyzing such processes are challenging when the system is large and its operating condition varies widely across different years, seasons, and power demand levels. Multicondition analysis of cascade vulnerability is needed to answer several key questions: Un- der what conditions would an initial disturbance remain localized rather than cascade through the network? Which network components are most vulnerable to failures across various con- ditions? What is the role of the network structure in determining component vulnerability and cascade sizes? To address these questions and differentiate cascading-causing disturbances, we formulated an electrical-circuit network representation of the U.S.-South Canada power grid—a large-scale network with more than 100,000 transmission lines—for a wide range of operating conditions. We simulated cascades in this system by means of a dynamical model that accounts arXiv:1804.06432v1 [physics.soc-ph] 17 Apr 2018 for transmission line failures due to overloads and the resulting power flow reconfigurations. -

Eastern Interconnection
1/31/2020 Eastern Interconnection - Wikipedia Eastern Interconnection The Eastern Interconnection is one of the two major alternating-current (AC) electrical grids in the continental U.S. power transmission grid. The other major interconnection is the Western Interconnection. The three minor interconnections are the Quebec, Alaska, and Texas interconnections. All of the electric utilities in the Eastern Interconnection are electrically tied together during normal system conditions and operate at a synchronized frequency at an average of 60 Hz. The Eastern Interconnection reaches from Central Canada The two major and three minor NERC eastward to the Atlantic coast (excluding Quebec), interconnections, and the nine NERC Regional south to Florida, and back west to the foot of the Reliability Councils. Rockies (excluding most of Texas). Interconnections can be tied to each other via high-voltage direct current power transmission lines (DC ties), or with variable-frequency transformers (VFTs), which permit a controlled flow of energy while also functionally isolating the independent AC frequencies of each side. The Eastern Interconnection is tied to the Western Interconnection with six DC ties, to the Texas Interconnection with two DC ties, and to the Quebec Interconnection with four DC ties and a VFT. The electric power transmission grid of the contiguous United States consists of In 2016, National Renewable Energy Laboratory simulated a 120,000 miles (190,000 km) of lines year with 30% renewable energy (wind and solar power) in 5- operated -

We expanded our footprint and doubled the number of registered entities in our region, increased staff such that more than 50 percent have been with the company two years or less, and made several governance changes, including reworking our organizational group structure and increasing the size of our board (notably 14 of 23 directors joined in 2019 or 2020). On top of all of these changes, we (like many others in the industry) transitioned to fully remote work for much longer than anyone would have predicted as a result of the COVID-19 pandemic. All of these changes have happened in my short tenure as President and CEO. Late June marked my two year anniversary serving in this role, and as I reflect back on all that has happened during this time, I find myself wondering, “What does it mean to be a fearless leader?” In considering this question, I happened upon the website www.leadfearlessly.com, which describes fearless leaders as those that embrace change, influence and motivate others to become more fearless, to be open to change, and to grow and adapt. -
