Flywheel energy storage is a mechanical Energy storage with high power, fast response, high frequency and long life, which is suitable for transportation (rail transit, automobile), emergency power supply, power grid quality management (frequency modulation) and other fields. Flywheel energy storage is an integrated technology, and its future development direction is high-speed, composite rotor, internal stationary and external rotating structure. Flywheel energy storage has broad application prospects, but it is currently in the early stage of market development.
At present, the domestic and foreign energy storage markets are characterized by large scale, fast speed, multiple policies, and a hot market. China's demand for energy storage is enormous and urgent, and it is in the early stages of demonstration to commercialization. The country has a series of policy support. The guidance issued by the National Energy Administration of China proposes that by the end of the 13th Five Year Plan, energy storage will transition from engineering demonstration to early commercialization; By the end of the 14th Five Year Plan, from the early stage of commercialization to large-scale application. Flywheel energy storage is a kind of mechanical Energy storage with high power, fast response, high frequency and long life, which has broad application prospects.
Operating principle of Flywheel energy storage
Flywheel energy storage is an advanced physical Energy storage derived from . It refers to an energy storage method that uses electric energy to drive the flywheel to rotate at a high speed, converts electrical energy into mechanical energy, drives the motor through the flywheel inertia when needed, and converts the stored mechanical energy into electrical energy output (the so-called flywheel discharge). Unlike other battery technologies, its advantages are reflected in its short-term, high-frequency, and high-power charging and discharging characteristics, mainly applied in fields such as power grid frequency regulation, grid connection of new energy power stations, rail transit, and high-power UPS (Uninterruptible Power Supply).
Technical features of Flywheel energy storage
Flywheel energy storage is a power type Energy storage with minute second level, high power, long life and high efficiency. Compared with other technologies, Flywheel energy storage is characterized by almost no friction loss and small wind resistance; The specific power can reach more than 8 kW/kg, which is far higher than the traditional electrochemical Energy storage; Its lifespan mainly depends on the fatigue life of flywheel materials and the lifespan of electronic components in the system. At present, the service life of Flywheel energy storage can reach more than 20'a, and the service life is not affected by the depth of charging and discharging; No harmful substances are generated during operation; Almost no maintenance is required during operation; Good adaptability to working conditions and environment, able to work normally at -20~50 '℃.
