Dong Energy is to integrate a battery system into its Burbo Bank Offshore Wind Farm.
The addition of the 2MW battery system, set to be installed by the end of the year, will enhance the capability of the 90MW wind farm. It will be the first time an offshore wind farm is integrated with a battery system to provide frequency response to help keep the grid frequency stable at 50Hz and maintain the operability of the grid.
The frequency of the grid is a continuously changing variable which must remain close to 50Hz. If the frequency was to deviate from these limits, it would affect everything plugged into the grid, from home appliances to power stations. The ability to inject or reduce bursts of active power allows the grid to rapidly respond to changes in frequency.
The 2MW battery system will be supplied by ABB. Burbo Bank Offshore Wind Farm has been fully operational since 2007 and is capable of supplying up to 80,000 U.K. homes.
