The voltage/var problems associated with serving urban areas that import large shares of power during peak load hours have slowly been gaining recognition by the international electric power community ...

A new report released in early March by the North American Electric Reliability Corp. (NERC) found that loss of reactive power was the most likely outcome from a severe solar storm that was centered ...

VARs (volt-amps reactive) are a measure of reactive power, the amount of power that an inductive generator, such as a wind turbine, consumes from the grid. When too much reactive power is consumed it ...

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 ...

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 ...

The networks that transmit and distribute electrical energy are continually facing new demands due to changes in power generation and load structure. For example, in many regions power grids are ...

Toshiba Electronics Europe has unveiled the ST2000JXH35A, a 6500V, 2000A press‑pack injection enhanced gate transistor (IEGT) designed for high‑voltage DC power transmission, industrial motor‑drive ...
