Dynapower Co. LLC, a Vermont-based supplier of power conversion systems, says it commissioned over 50 MW of grid-tied, bi-directional energy storage inverters in December 2012. According to the company, the inverters are the lynchpin of energy storage systems that connect to the electric grid via a variety of storage mediums, including lithium ion and lead acid batteries.
"Our bi-directional inverters, delivered from our Energy Management Systems group, are being used by utilities and integrators in a variety of applications, including renewable energy, frequency regulation and VAR support for grid stability," says Adam Knudsen, president of Dynapower. "December's commissioning covered multiple projects, including a single installation rated for continuous duty of 36 MW with an overload rating of more than 45 MW."
Dynapower says these projects will demonstrate how energy storage and power management technologies can help grid-scale wind and solar PV power systems address intermittency issues by utilizing an energy storage and power management system that optimizes the delivery of energy, in addition to providing regulation service to the utility market.
