This paper explores the control and operational aspects of integrating a short‐ and long‐term storage mix, known as smart energy storage system (SESS), into a cage induction generator based wind power system. Embedding such an SESS with wind power system not only provides the solution for intermittency but also makes the system dispatchable. The fuel cell/electrolyzer subsystem of SESS is employed to provide long‐term energy balance by utilizing H 2 as medium, whereas an ultracapacitor is employed as a buffer storage for transient compensation. The control scheme enables the integrated system to operate seamlessly in islanded and grid‐connected modes, fulfilling the operational requirements. The system configuration is proposed, control scheme designed, and the detailed dynamic modeling developed for each component of the system. Expected behaviors during the sudden load change and wind speed variations are observed by mathematical simulation. Finally, the results of the analysis are summarized with their applicability to real system, and the limitation/further scope are indicated. © 2011 Institute of Electrical Engineers of Japan.
