초록

늘어나는 전력 수요와 탄소배출을 줄이기 위하여 정부는 신재생에너지 및 에너지저장장치 도입을 장려하고 있다. 정부 는 2020년까지 ESS 누적용량을 2GW로 확대할 예정이다. ESS 도입을 통하여 전력 피크를 줄일 수 있으며, 시간대별 차등요금제를 활용하여 남는 전력을 판매할 수 있다. 본 논문에서는 ESS 보급 확대에 따른 비용을 분석을 위한 모형을 제안하였으며, 2035년까지의 ESS 발전량과 발전단가를 분석하였다. 또한 ESS와 신재생에너지 연계에 따른 경제성 분석을 위하여 태양광발전 및 풍력발전 연계에 따른 사례연구를 진행하였고, ESS 보급 촉진을 위하여 정부의 추가적인 보급지원 정책이 필요함을 시사하고 있다.

Currently, the government is encouraging the introduction of energy storage system to reduce carbon emissions and peak power demand. The government is planning the cumulative capacity of ESS of 2GW in 2020. By utilizing charge and discharge of the ESS, it is possible to sell the surplus power to utility and electricity market. This paper suggests the model that economic feasibility of energy storage system for planning the construction of power generation facilities in 2035. Our results of simulation indicate the energy storage plan of utility for constructing renewable energy facilities is need to incentives from the government to encourage power utilities and expansion of ESS.
