ABSTRACT:
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.

CONCLUSION:
The
HMGs are the most prevalent configurations for smart microgrids.
Conventionally, in an HMG, the ac and dc groups of microgrids have been
interconnected by the parallel - connected BILPCs. This connection brings many
problems into the control and operation of an HMG. The UIPC has been presented
in this paper, as a new and effective solution for this problem, instead of
using the parallel-connected BILPCs. Also, a new optimal H∞ filtering-based
fuzzy control scheme has been proposed for the LPCs in the UIPC to increase the
flexibility. The simulation results have confirmed the flexible power
transferring performance of the HMGs during various conditions using UIPC.
