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 ...

NGCP welcomes Terra Solar Power Project as a significant addition to the country’s growing renewable energy capacity, ...

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 ...

Designers of dc/dc switching power converters face the challenge of controlling EMI (electromagnetic-interference) emissions produced during normal operation. If large enough, these emissions conduct ...

National Grid Corp. of the Philippines (NGCP) cautioned that a heavy reliance on intermittent power sources may pose ...

Using sophisticated power electronics and communications systems to improve power system efficiency, flexibility and reliability is increasing interharmonic distortion and putting new equipment ...

One concern some observers raise about the growth of inverter-based resources, such as solar, wind, and battery storage, supplying the power grid is that they don’t provide inertia. Inertia has ...

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 ...

WHILE the Terra Solar Power Project would significantly increase the country’s renewable energy mix, the National Grid Corp.

Power-transformer designs minimize weight and cost based on three assumptions: (1) the power source is a sine wave, (2) the frequency is fixed, and (3) the voltage will not exceed a specified maximum.
