Abstrakt: The paper proposes an instantaneous power theory (IPT) based an improved low voltage ride-through (LVRT) strategy for photovoltaic-proton exchange membrane fuel cell (PV-PEMFC) based grid following hybrid microgrid architecture. The concept of the instantaneous power theory-based proportional-integral control (IPT-PIC) mechanism has been introduced to enhance the dynamic response of the grid-tied power electronic medium. Based on the direct quantities measured, the processed IPT-PIC output has been used to regulate the active and reactive current injection during the grid side contingencies. Besides, the instantaneous power theory-based fuzzy current control (IPT-FCC) mechanism has also been proposed and compared with the conventional instantaneous power theory-based approaches and found to be suitable for real field applications, particularly in the hybrid microgrid architecture. The percentage improvement of the LVRT capability has been found in the detailed simulated platform using MATLAB/Simulink 2021a. Furthermore, the response time, computational burden and real-time applicability have been evaluated in the dSPACE DS1103PPC controller board. [ABSTRACT FROM AUTHOR]
