Hybrid microgrids inertia controls have been dependent on rotating sources as reference for the frequency control for the network in the islanded mode. However, with the increasing share of static sources outnumbering the former type of generation, and the high R/X ratio of the interconnecting lines due to which proportional power sharing is hampered, the control strategy demands an augmentation. This paper proposes an inertial response strategy using the Takagi-Sugeno (T-S) Fuzzy logic based derivative control for the hybrid microgrids where static sources such as Photovoltaic systems (PVs) and the interlinking converters (ICs) lead the stability reference of the network followed by rotating sources, and the latter is also responsible for the proportional load sharing along with the static sources. The simulations performed on the hybrid microgrid demonstrate the efficacy of the proposed T-S Fuzzy logic based derivative controller for inertial response over the conventional proportional-derivative (P-D) controller, where the latter is generally used for obtaining an inertial response.
