As the penetration ratio of renewable energy known as inverter based resources(IBR) to power system increases worldwide, large amount of IBR causes various problems. Most of the IBR currently used in the Korean power system are Grid Following Inverter(GFLI) and have an output issue due to unstable phase angle when the grid disturbance occurs. In addition, there is a limit of instantaneous inertial output due to basic controller structure and delay of Phase Locked Loop(PLL). Under these circumstances, Grid Forming Inverter(GFMI), which self-controls voltage and phase angle like a synchronous machine, is attracting attention as a alternatives that can contribute to increasing system stability and inertial energy. In this paper, GFMI with various power control was constructed in PSS/e User Defined Model(UDM), and the output characteristics of the GFMI in the test system were verified through System Frequency Response(SFR) and Per Unit(PU) based controller configuration. Then, the GFMI model was integrated into the Jeju system in Korea and the output characteristics in case of disturbances were compared in PSS/e simulation. When compared to existing GFLI, it was confirmed that the GFMI contributed to more initial inertial energy and injected stable reactive power for voltage control. Therefore, the need to increase the robustness and stability of the Jeju system through the GFMI ESS control mode was verified.
