MingYang Smart Energy has deployed energy storage technology at its 43MW Huian Quanhui offshore wind farm in Fujian, China's. Quant-Cloud, a subsidiary of MingYang, developed the storage technology to enhance the typhoon resiliance capabilities of MingYang's offshore wind turbines.
An energy storage system is installed in the tower of each turbine to serve as a backup power supply. Backup power supply can ensure the continuous operation of the yaw system in the extreme case of power failure and reduce the load of the turbine. When a power outage is caused by typhoon, normal operation of the wind turbine’s yaw system has to be maintained to prevent excessive load on the grid, caused by yaw failure.
