Distributed energy resources (DERs) with advanced controls can provide services to the grid such as frequency response. However, to do so, unlike conventional generators, DERs typically have to ...

Researchers in the United States have created a droop control strategy for grid-forming inverters that purportedly improves power system frequency stability. By using an exponential active ...

PJM Interconnection has received the first frequency regulation services from small-scale demand resources under new rules allowing smaller projects to participate in PJM's Regulation Market. The two ...

For decades, electricity regulators have treated tight control of grid frequency as a basic sign of power system security. If the frequency stayed close to the nominal value, the system was considered ...

The electricity sector is at an inflection point. The historical model of centralized, monopoly-provided electric service is under pressure from technological change, shifting market forces, evolving ...

How to measure harmonics in a power system. Methodologies for reducing power system harmonics. A look at "triplen" harmonics. The IEEE standard 3002.8-2018, “Recommended Practice for Conducting ...
