As a power network isolated from neighboring countries, the electricity infrastructure in South Korea (also called the Republic of Korea) requires a high level of preparation for adopting future grid technologies. System plans must provide a practical solution for power system expansion that complies with strict reliability performance criteria, including contingencies (faults) on the 765-kV transmission system. System improvements must also provide a practical solution for exchanging power between the mainland and Jeju Island, which is viewed as a carbon-free area because of the expected development of wind generation.
