초록
본 연구에서는 마이크로그리드 기술을 활용한 에너지자립섬 모형설계와 새로운 평가체계를 구축하고자 한 다. 대상지역은 가사도를 선정하여 ESS(Energy Storage System)가 연계된 신재생 발전시스템의 시뮬레이션 분석, 경 제성 평가, 이산화탄소 배출저감에 따른외부비용 평가를 실시하였다. 분석결과, 가사도의 기후조건 및 부하패턴을 고려하였을때, 태양광-풍력-디젤발전과 ESS가 연계된 발전시스템이 가장 적합한 것으로 나타났다. 새로운모형을 통해 도출된 발전단가는 $0.462/kWh로 디젤발전 중심의 운영시스템 보다 $0.134/kWh 낮게 산정되었고, 외부비용은 디젤 중심의 발전시스템 대비 연간 $7,511를 비용절감효과를 나타내는 것으로 분석되었다.
Abstract
The purpose of this study was to design and evaluate an optimal energy supply system for the isolated island, Gasado, with microgrid technology. Simulation of a renewable energy power system, including energy storage (an energy storage system - ESS),economic analysis, and evaluation of external CO2 costs, was conducted for Gasado. The results showed that a renewable power system, supplied with ESS, was the best option, considering climatic conditions, and the load pattern for the target area. The cost of electricity was estimated at $0.462 /kWh, which was lower than that for an equivalent diesel powered system, by $0.134 /kWh. The proposed system can reduce CO2emissions by 70%, and can thus save $7,511 annually in external costs.
