Abstract:

Nowadays, the environmental pollution and energy shortage are becoming increasingly serious. New energy wind power generation can effectively solve related problems. However, due to the wind speed fluctuations, the power generation system faces the challenges of power fluctuations and frequency instability. Flywheel energy storage control technology can achieve the conversion of kinetic energy and electric energy using high-speed rotating bodies, and has the advantages of high-frequency charge/discharge capability, millisecond-level response and extended service life. Flywheel energy storage control technology can be used to suppress power fluctuations in new energy wind power generation systems and maintain the stability of the power grid. It can also improve the frequency response characteristics of the system, enhance the voltage quality at the grid connection point, and suppress voltage flicker and harmonics, thus providing key technological support for the secure and stable operation of high-proportion new energy power systems.

Key words: flywheel energy storage control technology, new energy, wind power, power system
