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 ...

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 ...

In the last decade, volt/volt-ampere-reactive (VAR) optimization became one of the most desirable applications implemented on the distribution system. Primary objectives of volt/VAR control include ...

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 ...

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 ...
