A Study on the Generating Capacity Expansion Characteristics in Jeju Island

제주지역 전력공급 대안과 특성분석

Although Jeju island Is connected with main network system by HVDC cable line, it's network assumes the form of independent system in an operating point of view. Therefore Jeju needs it's own independent capacity expansion planning. Continuos growth of demand and increase of antiquated plants in Jeju requires additional generating capacity. This paper analyzes characteristics of two alternatives which include it's own expansion of facilities and capacity expansion of network system for Jeju island. Furthermore this paper evaluates economic efficiency of those alternatives and analyzes long-term program of demand-supply of electricity.
