Microgrids can allow facilities to maintain continuity of electric power service for critical loads during long duration outages. Most microgrids use a variety of power sources and energy storage to provide on-site generation, including conventional generators, renewables, and energy storage. Traditional batteries typically complement diesel generation operation but are rarely used to replace generators, primarily because of the high cost and limited energy duration of commercially available battery technologies. Flow battery technology offers a potential alternative to traditional chemistries to reduce dependence on conventional generators while still ensuring system reliability. Vanadium redox flow batteries offer unique differentiators to lead acid and lithium-ion battery technologies such as increased safety, longer rated duration, and longer life. However, the nascency of this technology and limited understanding of reliability and operational performance, coupled with high equipment cost, typically limit the opportunities for field deployment. This talk covers the fundamentals of microgrids and discusses the results from laboratory tests of a vanadium flow battery that evaluated the potential for such a battery to replace existing diesel generators.
