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 ...

Electricity transmission network operators are being tasked with adding more renewable energy resources to the power grid. The use of static VAR compensators (SVCs) is growing as a means to control ...

The Solution As part of the U.S. Department of Energy and EPRI “Turbine Verification Program,” Enron Wind has developed a closed-loop power plant voltage control called “dynamic VAR (DVAR).” The DVAR ...

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 ...

Spain’s grid operator Red Eléctrica and regulator CNMC have launched real-time voltage control services, allowing renewable energy installations to provide dynamic grid support under a new regulatory ...

The European Network of Transmission System Operators for Electricity (Entso-E) has published its final root cause report on the April 28, 2025, blackout in Spain and Portugal, finding failures across ...

The traditional grid has been reliable because it is centralized. When a customer flips a switch, the lights turn on. Originally, the grid was designed with large generators accounting for much of the ...

Nearly a year after the Iberian blackout, an expert panel has released its final report regarding the causes that resulted in ...

Hoymiles is unveiling its 4-in-1 microinverter, the HM-1200, which is the first designed with reactive power control for 4 solar panels. It still offers the same features as Hoymiles former released ...

Editor's note: I thought this might be a thought-provoking white paper for Power Engineers in our audience. It's quite in-depth but will surely lead to some excellent insights into controlability and ...
