Abstract-

Ensuring stability and reliability in power converters within modern power systems is of paramount importance. This paper introduces an innovative grid-forming control approach employing an Inertial Phase Locked Loop (IPLL) method. This novel technique combines phase-locked loop principles with inertial response features to bolster the stability and synchronization of power converters with the grid. The IPLL method delivers precise and resilient phase and frequency synchronization, essential for maintaining grid stability under dynamic conditions. By harnessing the unique attributes of the IPLL, the proposed control strategy enhances power converter performance, ensuring they can effectively support grid stability and facilitate grid-forming operations. The effectiveness of the IPLL-based grid forming control is validated through both simulations and experimental results, showcasing its potential to improve the robustness and reliability of power converter systems across various operating conditions.
