US utility Dominion Energy will be utilising the first Mobile SVC STATCOM technology provided by Siemens to ensure grid stability during disturbances and faults.
The solution keeps the grid stable providing fast and controlled reactive power. Mobile STATCOM gives the utility an unprecedented level of flexibility to move the device anywhere grid support is needed, especially in cases of unexpected outages from extreme weather or unplanned events. Instead of several years of planning and executing a permanently installed substation project, the Siemens STATCOM technology can be moved within days.
“By using this device, Dominion Energy is meeting today’s need to maintain reliability but also prepare their transmission system for future challenges,” said Mirko Düsel, CEO transmission solutions at Siemens Energy Management.
According to a release, the flexible nature of the substation technology will also help Dominion Energy to manage the growing number of renewable and distributed energy resources on its power grid. Temporary STATCOM installations help keep the grid stable while the utility is able to allow sufficient time to plan for renewables on its system. The substation technology also responds to any faults on the network within milliseconds.
The first mobile STATCOM device is expected in mid-2018.
