SVC Light (Static Var Compensator) with Energy Storage

The SVC Light (Static Var Compensator) with Energy Storage is the latest development in the FACTS (flexible alternating current transmission systems) family. The technology combines SVC Light with scalable Li-Ion battery storage technology.

The present rated power and capacity of storage is typically in the 20 MW range for periods of approximately 15-45 min, but this technology can be scaled up to 50 MW of power for 60 min and more.

The system enables dynamic control of active as well as reactive power, independent of each other. Fast reactive power control means that grid voltage and stability can be controlled quickly. Active power control is enabled with dynamic energy storage by levelling out power fluctuations from intermittent generation sources such as wind and solar energy.

The system can be connected to the grid at transmission as well as sub-transmission and distribution levels to compensate for voltage and current fluctuations, thereby allowing more power to flow through the network while maintaining safety margins and increasing stability.
