AEG Power Solutions, a global provider of power electronic systems and solutions for industrial power supplies and renewable energy applications, has been chosen by UniEnergy Technologies (UET) to supply Protect SC.600 storage converters for their Uni.System™. The Uni.System provides unlimited cycles, 20 year life, and use of the battery’s full state-of-charge.
UET delivers MW-scale energy storage solutions for both power and energy simultaneously. Projects to date include for utilities, commercial and industrial, and micro‐grids. The systems are able to help overcome challenges in adding renewable energy sources to the public grid, including grid stabilization and grid leveling. The core patented technology is an advanced vanadium flow battery, with breakthrough electrolyte developed at PNNL, with funding from the US DOE.
The AEG Power Solutions (AEG PS) storage converters are installed at two sites. Firstly, at UET’s headquarters in Mukilteo, Washington, USA on the Harbour Pointe distribution circuit, they are being used by UET for production and acceptance testing in a 2MW/4hrs (8 MWh) installation. Secondly, the storage converters are included in UET’s 1 MW/4hrs (4 MWh) deployment on the Turner distribution circuit at a manufacturing facility in Pullman, Washington, USA.
Protect SC.600 is a bi-directional power converter based on IGBT technology. In battery energy storage systems, it transforms the battery’s chemically stored energy into a useful grid service by supply the right electric component, at the right time, with the right amount and form of electrical power.
“With the increasing shift to renewables, there is a growing need to manage how electrical power is provided to the grid,” says Stefan Kempen, Product Manager at AEG Power Solutions. “UET’s energy storage systems are an innovative solution that will help utilities add more renewables, and simplify how they are integrated with other sources.”
