Variable-speed operation of wind turbines (WTs) achieved through electronic converters can decouple wind generator dynamics from power systems. Besides, the wide rotor operation range makes it possible for the WT to tap the potential of kinetic energy (KE) in the rotating mass. This study provides an overview of utilising KE from WTs for grid connections. The availability of KE in WTs is acquired by the rotor speed alternation, both in static and dynamic processes. For the static state, the rotors of WTs operate at a pre-defined power curve which leaves the generation margin for KE release; while for the dynamic process, the KE is passively changed by the imbalance between mechanical and electrical power. Some emerging technologies in frequency regulation and low-voltage ride through capability with the participation of KE stored in WTs are investigated. The applications of KE in terms of wind smoothing are summarised as well. Finally, this literature review also discusses some potential future applications of KE management.
