Wind power hybrid energy storage device

Hybrid energy storage, with its high power density, energy density, and long lifespan, has become a crucial support for grid-connected wind power systems. 5 Energy-based storage (e.g., batteries and hydrogen) is effective for smoothing long-term power fluctuations, while power-based storage (e.g., supercapacitors and flywheels) responds quickly to transient fluctuations.
