Abstract

Most energy generating systems in island areas are diesel energy generation using fossil fuel. The transportation cost of fossil fuel to the island areas makes generation cost three to four times more expensive. To solve this economic loss, the establishment of energy independent island through introduction of renewable energy generation system in the island areas is being considered. Prior research are generally focus on major island areas such as Jejudo, Ulleungdo and Gapado etc. However, to verify about applying renewable energy generation systems on the island areas, considering the all types of characteristic of the island areas such as high economic loss from energy generation or small population of less than 100 people is essential. This study is conducted as case study on Baengnyeongdo which has high economic loss and Oedo which has small population of less than 100 people. To examine the feasibility of applying renewable energy generation system in Baengnyeongdo and Oedo, a combination of existing diesel energy generation system and renewable energy generation system was proposed and economic analysis using NPV(Net Present Value) and LCOE(Levelized Cost of Energy) was proceeded. The experiment was conducted using simulation, HOMER(Hybrid Optimization Model for Electric Renewable) was used as simulation program. Environment and weather data of Baengnyeongdo and Oedo and renewable energy genration system data obtained from KEPCO(Korea Electric Power Corporation), NREL(National Renewable Energy Laboratory) and HOMER were used as simulation dataset. The optimal combination of energy generation system for Baengnyeongdo and Oedo was proposed and it was confirmed that there would be economic benefits if the introduction of the renewable energy generation system continued for more than 9 years.
