The distribution system, a key subset of the overall electric grid, provides power to residential, commercial and industrial customers. Voltage and reactive power management and control have been done ...

Robust control of reactive power and voltage is crucial for the stable and efficient operation of wind farms, particularly as renewable penetration increases worldwide. Contemporary strategies ...

Ameren Transmission Co. LLC has energized the first two of four innovative upgrades to ensure its grid remains stable during the utility’s transition to clean energy sources. Known as static ...

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 ...

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 ...

Significant advances in high-voltage direct current (HVDC) transmission are in step with rapid changes to energy systems worldwide. Shortly after POWER magazine began publication in 1882, the ...

German TSO 50Hertz on Tuesday became the country’s first grid operator to tender for market-based reactive power – electricity that flows back and forth in an alternating-current grid to maintain a ...

Your utility Power Factor is the ratio of the system’s Real Power and the Apparent Power (Eq. 1, Fig. 1). This unitless factor ranges from −1 to 1. The Power Factor ratio aptly describes the type of ...
