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 ...

Today's emphasis on implementing energy-efficiency programs and limiting peak demand growth is driving renewed interest in an effective method of implementing volt/var control on distribution systems: ...

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 ...

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 ...

Making the power grid more flexible, resilient, and efficient is the single most important objective for electric utilities today. A number of voltage-adjustment and reactive power correction ...

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 ...
