Abstract

Many efforts will have to be made on securing the stable supply of the energy due to the worldwide trend of controlling the utilization fossil fuels inducing global climate change. Renewable portfolio standard enforced to power companies over 500 MW capacity from 2012. Tidal current energy is one of the most interesting renewable and clean energy resources that have been less exploited. Especially, Korea has worldwide outstanding tidal current energy resources and it is highly required to develop a tidal current energy conversion system(TECS) in coastal region. So, we examine a tidal in-stream energy using a numerical model and estimate a tidal current potential for commercialization of tidal current power plant in the sea of the Bunamgun-do. Available tidal energy resources is also analytically estimated using a tidal farm method and the annual energy production of an optimal TECS arrays will be calculated with taking into account interference of lateral and longitudinal spacing.

최근 기후변화를 초래하는 화석연료의 사용을 감축하는 세계적 추세와 함께 에너지의 안정적 공급을 위해 많은 노력이 요구되고 있다. 또한 2012년부터는 500 MW 이상의 전기를 생산하는 에너지사업자는 신재생에너지 의무할당제의 적용을 받는다. 조류자원은 최근 각광을 받고 있는 신재생에너지이며, 이러한 조류자원은 매우 크지만 제한된 지역에 분포하고 있으므로 조류에너지를 효과적으로 이용하기 위해서는 반드시 기술적, 경제적인 측면의 평가가 요구된다. 그러므로 본 연구에서는 부남군도 해역에 부존하는 조류자원 실용화 기술개발을 위하여 조류에너지원에 대한 자료수집 등의 현황분석과 수치모델을 이용한 시뮬레이션 등을 통하여 조류에너지 분포도를 조사하고 이용 가능한 연간 에너지 생산량을 산정, 조류발전기를 모듈화 하여 최적의 조류발전단지 구성기술을 개발하고자 한다.
