摘 要：In Jeju Island, which is the largest island in South Korea, main portion of the required electric power is provided from the mainland through two HVDC lines. Since Jeju HVDC is operated on frequency control mode and it covers entire power variations in Jeju Island, it has a most significant impact on the power system in Jeju Island. The large-scale wind generation also could have significant impacts on the power system in Jeju Island. This is because the total capacity of wind power is considerable large compared to the load in Jeju Island and it can threaten the stable operation of the power system. In this paper, dynamic modeling of wind farms and Jeju HVDC is developed using PSS/E. Wind farms are composed of doubly fed induction generators （DFIGs）. Model writing technique is used to develop user-defined models for controlling HVDC frequency and imposing maximum penetration limit. The simulation results indicate the effectiveness of the dynamic modeling for stability studies of the power system in Jeju Island.
