Study on the Configuration of Grid Stabilization Resources for Achieving CFI in the Jeju Power System

This study evaluates the impact of power facilities and standards on the stable operation of the Jeju power system, which comprises carbon-free power sources in alignment with the Carbon-Free Island (CFI) 2030 initiative. It analyzes the contributions of grid-forming energy storage systems (GFM-ESS), high-voltage direct current (HVDC) systems, synchronous condensers, primary frequency response, and fast frequency response to system stability. The study also investigates operational strategies for maintaining stability in scenarios without synchronous generators, incorporating grid stabilization resources. Furthermore, it identifies the required capacity of each stabilization resource to ensure the reliable operation of the Jeju power system.
