What Is a Phasor Measurement Unit and How Does it Make the Grid More Reliable?
A Phasor Measurement Unit, also called a PMU or a synchrophasor, is a key tool used on electric systems to improve operators’ visibility into what is happening throughout the vast grid network.
The Electric Load Curve – Once Predictable, Now Fickle
Variables such as DER penetrations, growth of EVs, electrification of heating loads, and willingness of consumers to use energy flexibly in response to price signals are drastically impacting load curves and thus the future of electric grid operations.
How Electric Operators Maintain Acceptable Voltage
Utility professionals must have a basic understanding of the principles of voltage regulation as the utility grid becomes increasing distributed. System operators and designers must learn new techniques for managing voltage, and customers installing DERs will need to understand why interconnection rules include requirements associated with voltage support.
Is Artificial Intelligence the Next Step for Smart Grids?
Utility companies must think of themselves as technology companies, not just energy companies. The importance of this distinction will continue to grow as artificial intelligence (AI) is required to manage the smart grid.
New NERC Standards Extend Cybersecurity Protection for Energy Companies
NERC recently adopted a new mandatory Critical Infrastructure Protection standard to address cybersecurity supply chain risk management, marking another important milestone in efforts to better secure the nation’s bulk electric system. 
Ancillary Services Keep Electric Grids Running
Ancillary services are the services (other than energy) required by system operators to ensure reliable operation of the electric grid. They are used to keep the system running or to restore the system when contingencies occur.
The Third Network – Communications Integrated into Gas and Electric Networks
As gas and electric utilities move forward with implementing advanced grids, they are finding that they must develop and manage a new “third grid” – the communications system that is integrated into the energy network.
