New Technology Combines SVC Light with Energy Storage

ABB has launched SVC Light (Static Var Compensator) with Energy Storage as its latest development within the FACTS (Flexible Alternating Current Transmission Systems) family.

The new technology combines SVC Light with a highly scalable battery storage technology.The present rated power and capacity of storage is typically in the 20 MW range for periods of approximately 15 to 45 minutes, but this technology can be scaled up to 50 MW of power for 60 minutes and more.

ABB’s SVC Light with Energy Storage enables dynamic control of active as well as reactive power in a power system, 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. This technology also facilitates load support and ancillary grid services such as area frequency regulation.

SVC Light is a system connected to the grid at transmission as well as sub-transmission and distribution levels, using state-of-the-art power semiconductors. The energy storage system is based on Li-ion batteries combined with SVC Light.
