FERC’s Order 827 changed the rules for wind (and some solar) power providers regarding reactive power. Read this white paper for a brief history of FERC orders related to renewables, and an overview ...

Fundamentally, electrical power is developed, delivered, and consumed as voltage and current. In a simple direct current (DC) device such as a flashlight, the power (the brightness of the bulb) is the ...

We have a number of recognized transmission and distribution experts serving on our board of "Grid Masters." Several times each month we’ll post what we judge to be the toughest questions that also ...

As coal, gas, and nuclear plants are retired, and wind and solar resources are added to the power grid, stability can become a problem. Understanding the solutions that are available to help manage ...

Correctly installing capacitors at the terminals of your motors can lower reactive power requirements and increase system power factor. Induction motors are the primary source of rotary power in the ...

As coal and gas plants are taken offline to be replaced by wind and solar, grid stability and system strength can become serious challenges. This is due to the inherent inertia provided by rotating ...

Editor's Note: This story was originally published in the May 2007 issue of Scientific American and is being reproduced here on the occasion of the fourteenth anniversary of the 2003 blackout in the ...

US researchers have proposed the use of solar inverters in utility-scale solar assets to replace expensive voltage compensators, in order to provide voltage support at night. They said reactive power ...
