Title:
OPERATING A WIND POWER PLANT INCLUDING ENERGY STORAGE DURING GRID FAULTS
Document Type and Number:
WIPO Patent Application WO/2012/000517
Kind Code:
A3
Abstract:
Methods, systems, and articles for operating a wind power plant during a grid fault. An energy storage system may be configured to transfer reactive power from the energy storage system to a power grid in response to detecting the grid fault. While providing reactive power to support the grid, the energy storage system may be charged with active power generated by at least one wind turbine generator during the grid fault. Furthermore, the energy storage system supports grid recovery by providing active power after a grid fault is removed.
