This material is based upon work supported by the U. Department of Energy's Office of Energy Efficiency and Renewable Energy (EERE) under the Solar Energy Technologies Office Award Number 38637. This report was prepared as an account of work sponsored by an agency of the United States. . These large systems are often difficult to evaluate prior to deployment because of their large size. The fundamental form and feasible functionalities of power systems are rapidly evolving as more inverter-based resou ces (IBRs)1 are integrated into the power system [1]. Each variant comes with unique applications, technical requirements, and regulatory implications. Additionally. . Unlike grid-following inverters, which rely on phase-locked loops (PLLs) for synchronization and require a stable grid connection, GFMIs internally establish and regulate grid voltage and frequency.
