Application Analysis of Energy Storage System in Wind Turbine Frequency Modulation

In wind turbine applications, the energy storage system (ESS) functions as a stabilizing entity, addressing the discrepancies between wind power output and load demand. The ESS possesses significant advantages: its rapid responsiveness, bidirectional adjustment capabilities, and its operation unaffected by the wind turbine's operational state. This research examines the frequency modulation in wind turbines and assesses the ESS's involvement in this context. We conducted tests to gauge the ESS's efficiency in ensuring consistent power output from wind turbines and thwarting abrupt shifts in system frequency. The findings reveal that integrating the ESS into wind turbine operations effectively minimizes power fluctuations and offers reliable frequency modulation performance.
