Can energy storage smooth wind power fluctuations?
Abstract: Energy storage can smooth the power fluctuations of wind power integrated into the grid. Due to the strong adaptability of the empirical mode decomposition (EMD) algorithm to non-stationary signals, it is widely used in wind power smoothing control strategies.
How ESS is used to smooth fluctuating power?
In general, the smoothing of fluctuating power is carried out with an ESS such as a battery energy storage system, fuel cell/electrolyzer, superconducting magnetic energy storage, flywheel energy storage system, energy capacitor system as well as without any energy storage system.
Can energy storage systems be used for wind power smoothing?
Alternatively, energy storage systems (ESSs) can be used for wind power smoothing purposes. These elements are usually connected at the DC–link of wind turbines or even directly to the AC side. Using ESSs, wind power smoothing methods can consider different control approaches and numerous variable inputs to control charging/discharging cycles .
