Domestic flywheel energy storage unit breaks through 1MW for the first time
CTOnews.com November 14 news, recently, led by China Nuclear Power Huineng Inner Mongolia Autonomous region science and technology project "MW (megawatt) class advanced flywheel energy storage key technology research" project flywheel energy storage power reached 1MW for the first time, this is the domestic single flywheel for the first time to achieve the maximum grid-connected power, completed the core components of flywheel, motor, magnetic bearing and stand-alone integrated control test.
Through the long-term operation of the hybrid energy storage system in the Erlianhot wind farm, CNNC Huineng's demonstration project will explore the operation mode in which flywheels, batteries and wind farms work together to meet the requirements of primary frequency modulation. to find the most economical solution for primary frequency regulation of wind farm.
CTOnews.com learned that according to the plan, the three 1MW flywheels will continue to carry out array coordinated control tests and then be merged into the China Nuclear Energy Exchange Erlianhot 99MW Wind Farm to form a hybrid energy storage system with 3MW / 3MWh battery energy storage to provide primary frequency modulation service for Erlianhot Wind Farm.
This project will provide important experimental data and practical experience for exploring the practical application of flywheel energy storage array system in primary frequency modulation of wind farm. In July 2020, the flywheel and battery hybrid energy storage system participated in the scientific experiment of primary frequency regulation of power grid, which proved that the characteristic of fast high frequency response of flywheel is the most suitable for primary frequency regulation application, which can effectively improve the operating condition of battery energy storage system and prolong battery life.
