In this paper, in order to configure a hybrid microgrid system (HMS), a topological representation for nine-switch converters (NSCs) has been introduced to interface multiple renewable power generation systems. Here, a 22 kW self-excited induction generator is interfaced with a 7.5 kW doubly fed induction generator using an NSC. The active power flow in the system has been managed by a battery energy storage system connected at the Direct current (DC) link of the NSC. The grid-side converter of the Doubly-fed Induction Generator (DFIG)-based wind energy conversion system (WECS) manages the reactive power flow of the system. Moreover, the NSC helps in managing both the stator-side and the rotor-side power flow of the DFIG-based WECS. This proposed system is subjected to different time-varying loads, and the execution of the structure has been examined. This proposed system is simulated and modeled utilizing MATLAB/Simulink and verified using OPAL-RT 4510.
