본 연구는 전과정평가(LCA)를 이용하여 세제 기존 판매방식과 리필 스테이션 판매방식에 대한 환경영향을 비교하는 데 목적이 있다. 환경영향범주는 자원발자국, 탄소발자국, 오존층영향, 산성비, 부영양화 및 광화학스모그 등의 6가지 범주로 선정하였다. 기존판매 방식과 리필 스테이션 판매 방식간 환경영향을 비교한 결과는 리필 스테이션 판매방식이 기존 판매 방식에 비해 자원발자국 2.55-03 kg Sb eq., 탄소발자국 1.71E-01 kg CO<sub>2</sub> eq., 오존층영향 1.69E-05 kg CFC11 eq., 산성비 477E-04 SO<sub>2</sub> eq., 부영양화 1.55E-04 kg PO<sub>4</sub><sup>3-</sup> eq., 광화학스모그 1.64-03 C<sub>2</sub>H<sub>2</sub> eq. 정도 환경영향이 저감되는 것으로 나타났다. This study aims at comparing the environmental impact of the previous sales system with the refill station sales system using life cycle assessment. Environmental categories were selected a resource footprint, carbon footprint, an ozone depletion, an acidification, and eutrophication and a photochemical smog. As a result of comparing the previous sales system with the refill station sales system about the environmental impact, the refill station sales system reduced a resource footprint of 2.55E-03 kg Sb eq., a carbon footprint of 1.71E-01 kg CO<sub>2</sub> eq., and an ozone depletion of 1.69E-05 kg CFC11 eq., acidification 4.77E-04 SO<sub>2</sub> eq., eutrophication by 1.55E-04 kg PO<sub>4</sub><sup>3-</sup> eq., and photochemical smog by 1.64E-03 C<sub>2</sub>H<sub>2</sub> eq. compared to the previous sales system.

This paper presents the estimation of minimum BESS capacity for regulating the output of wind farms considering power grid operating condition in Jeju Island. To analyze the characteristics of wind farm outputs with a BESS, the real data of wind farms, Sung-San, Sam-dal and Hang-Won wind farm, located in the eastern part of Jeju island is considered. The wind farms are connected to Sung-san substation to transfer the electric power to Jeju power grid. Consequently, at PCC (Point of Common Coupling), it can see a huge wind farm connected to the substation and thus it can be expected that the smoothing effect is affected by not only the different wind speeds for each area but also the different mechanical inertia of wind turbines. In this paper, two kinds of simulation have been carried out. One is to analyze the real data of wind farm outputs during a winter season, and the other is to connect a virtual BESS to eliminate the unintended generating power changes by the uncontrolled wind farm outputs as shown in the former data. In the conclusion, two kinds of simulation results show that BESS installed in the substation is more efficient than each wind farms with BESS , respectively.
