ABB, the power and automation technology group, 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.
"This technology can play an important role when it comes to integrating renewables, especially in weak electrical networks" said Claes Rytoft, head of technology for ABB's Power Systems division. "It can be a key enabler in the development of more reliable and smarter grids."
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.
ABB is a global leader in FACTS technologies that help enhance the security, capacity and flexibility of power transmission systems. They enable an increase in the existing transmission capacity of a power network while maintaining or improving the operating margins necessary for grid stability.
SVC Light is a system that provides fast-acting reactive power compensation in high-voltage electricity networks. They compensate for fluctuations in the voltage and current of an electric grid, thereby allowing more power to flow through the network while maintaining safety margins and increasing stability.
