Study on development of Grid code and operation scheme of Jeju Island with high wind penetration

Lots of large-scale wind generation are currently being commissioned, with more planned for the near future in Jeju Island of Korea. The large-scale wind generation, however, could have adverse impacts on stable operation of power system. Accordingly for the stable operation of Jeju power system, the necessity to limit the wind installation is brought up recently and new wind power projects are restricted for now. To increase the wind penetration in Jeju Island, solutions in two respects is presented in this paper; Establishment of grid code for wind generation and development of coordinated operation schemes of Jeju power system.
