This paper aims to propose the small‐signal model of a wind turbine (WT) based on a doubly fed induction generator (DFIG) and a solid oxide fuel cell (SOFC) into the transmission network for dynamic stability analysis of the integrated system. The principal goal is to introduce the novel small‐signal model of the hybrid power system in the presence of the WT and SOFC power plants for analyzing of electromechanical oscillations. Therefore, the modeling of each generation unit of the integrated system in the same framework is illustrated. Besides, a comprehensive mathematical model is demonstrated from WT and SOFC units integrated with a synchronous generator (SG) and the infinite bus system. Based on the proposed model, the linear analysis is illustrated under different conditions for stability studies. Moreover, this study presents the influence of different portions of WT and SOFC units on the small‐signal stability. The simulation results represent the performance of the suggested model.
