A digital substation is a modernized electrical substation that replaces traditional analog equipment and copper wiring with digital signaling, intelligent electronic devices (IEDs), and fiber-optic communication. It enables real-time data exchange, advanced automation, and greater efficiency in managing grid operations and infrastructure health.
For decades, the idea of the digital substation hovered just beyond reach—a theoretical construct wrapped in futuristic language and layered with uncertainty. It was described as an “intelligent substation,” capable of processing...
Distributed generation resources takes a giant step forward BY KEN GEISLER, Siemens For the majority of its existence, the electrical grid has been powered with large, remote “centralized” generation. Centralized power plants often need to reach substations serving load centers that...
IESO stays ahead of Ontario’s rapidly changing marketplace BY PHILL FELTHAM, Editor-in-Chief Electricity Today Magazine Grid modernization is a buzz term used by regulators, utilities, and other participants within North America’s power sector. Modernizing the power grid is the proposed answer...
Addressing the impacts and the drawbacks BY ELIZAVETA MALASHENKO, CHRIS VILLARREAL, & J. DAVID ERICKSON, California Public Utilities Commission With grid modernization or “Smart Grid” efforts underway, cyber security is being recognized as an increasingly important factor in ensuring...
How to improve reliability by hardening the power grid BY BO ZENG, WEI YUAN & LONG ZHAO, University of South Florida North America relies heavily on its interconnected power grid. Throughout its history, the grid has provided years of reliable electricity to 300 million people to power home...
A coalition of large energy consumers and ratepayer advocates has filed a complaint with the Federal Energy Regulatory Commission (FERC), urging the agency to prohibit transmission owners from independently planning "local" transmission projects exceeding 100 kilovolts (kV). The coalition argues...
In a significant move that underscores the growing demand for reliable and sustainable energy to power the expanding digital infrastructure, the Federal Energy Regulatory Commission (FERC) has approved an interconnection agreement between Talen Energy, Amazon Web Services (AWS), and Exelon. This...
The evolving demands of modern power grids necessitate the adoption of advanced technologies that can provide enhanced efficiency, reliability, and flexibility. Smart transformers are at the forefront of this technological revolution, offering a range of capabilities that significantly improve the...
The electric power industry is increasingly having to evaluate the growing penetration of distributed energy resources (DER). New sets of challenges exist for planning and operating the grid, especially with the distribution systems in which these new resources must be integrated. Now electric...
Increasing the hosting capacity of distributed generation in power distribution systems is identified as key low-carbon solution to help meet the aggressive greenhouse gas emission reduction targets in the energy sector. The deployment of distributed generation technologies is creating a paradigm...
NEURAL GRID TAKES SMART GRID INTO THE CLOUD The Neural Grid represents more than Smart Grid v2.0—much more. Today, the smart grid implies the legacy mechanical power transmission and distribution (T&D) networks enhanced by pockets of automation, connectivity, and centralized IT systems. The...
