Flexibility Enhancement of Hybrid Microgrids Using Optimal H∞ Filtering-based Fuzzy Control of UIPC

The current study focuses on flexibility enhancement of hybrid or ac/dc microgrids (HMGs), which uses an improved Unified Interphase Power Controller (UIPC). The UIPC is adopted as an effective tool for interconnecting the HMG. A novel control system is suggested for UIPC line power converter (LPC). The proposed control scheme is an optimal H∞ filtering-based fuzzy inference system which is able to effectively provide a flexible control for the LPCs during system different conditions, as shown by simulations.
