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 ...

Power systems are undergoing a rapid transition toward operation with high penetration of renewable energy and power electronic interfaced devices—often ...

Discover how researchers are tackling the challenges of integrating renewable energy into power grids. A new study in Engineering presents a groundbreaking framework to manage uncertainties in power ...

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 ...

The interconnected power systems serving two-thirds of the United States and Canada are projected to maintain system frequency for at least the next five years, despite a changing resource mix that ...

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 ...
