Smart management of HVDC interface flow for Jeju island system with high penetration of wind energy

The recent concerns over the threat of global climate change and the requirements of national reduction of CO₂ emission have led to the diversification of energy resources and a large scale integration of renewable resources. For island systems, however, the penetration level of renewable energy should be limited to maintain the power system security perspectives to frequency and voltage stability. The main interest of this paper is the operation of Jeju island system with a high penetration level of wind energy. As an option to make a breakthrough against the technical constraints, this paper presents a smart algorithm to set the active power of HVDC (High Voltage Direct Current) interties, which are to supply the power deficit and to regulate the frequency of the system.
