  • 현재 우리는 화석연료의 고갈 및 에너지 수입 해외의존도의 심화, 최근의 고유가 등으로 신재생에너지원의 개발 및 이용, 보급 확대가 국가적 관심사항이 되고 있으며, 신재생에너지를 전원을 보급하기 위해 노력하고 있다. 정부는 2012년부터 RPS(Renewable Portfolio Standard)를 도입하여 신재생에너지전원의 비중을 설비용량의 5%(발전량의 7%)까지 확대하는 것을 목표로 하고 있다. 따라서 본 연구에서는 가격규제가 아닌, 보급목표를 규제하여 시장에서 가격이 결정되는 RPS를 도입하였을 경우의 현 전력수급계획의 수립절차에 대한 상세한 고찰과 문제점 분석을 통해 우리나라의 RPS를 반영한 최적 전원구성비를 도출하기 위한 방안을 GATE-PRO(Generation And Transmission Expansion PROgram) 모형을 이용하여 모색하고자 한다. 또한 이를통해 우리나라의 RPS도입이 전력수급계획에 미치는 영향을 살펴보고자 한다.

  • 기후변화협약 체결 당시 개발도상국으로 분류되어 있던 우리나라는 현재 온실가스 감축의무를 부담하지 않고 있으나, 우리나라의 CO2 배출량 및 배출량 증가율을 고려해 볼 때, 제2차 공약기간(2012년$\sim$2016년) 동안의 온실가스 감축의무 부담이 예견되고 있다. 온실가스 감축의무를 이행하기 위하여 정부는 2012년부터 RPS(Renewable Portfolio Standard) 제도를 도입을 고려하고 있다. 신재생에너지전원의 비중을 설비용량의 5%(발전량의 7%)까지 확대를 예상하여, 본 연구에서는 RPS 제도를 도입을 고려할 때 전원구성의 변화를 GATE -PRO(Generation And Transmission Expansion PROgram)모형을 이용하여 알아본 후, 이로 인하여 전기를 사용하는 용도에 따라 6가지 종별로 구분하는 현행 전기요금체계에 미치는 영향에 대하여 알아보고자 한다.

  • Korea's RPS, which requires that power generation companies obtain a minimum percentage of their generation by using renewable energy, will take effect in 2012. Based on the first-year law enforcement, generation companies have to satisfy 2% of RPS compliance ratio in 2012. Then, the required RPS compliance ratio will increase up to 10% in 2022. Thus generation companies need to construct power plants that utilize various types of renewable energy sources such as PV and wind power. This work is aimed to analyze the cost of such a renewable power source in terms of capital cost, capacity factor, and fuel cost. We provide the analytical expectation on the renewable power generation cost of 2012 focusing on PV, onshore/offshore wind, fuel cell, and IGCC, which are focused by government policy.

  • This paper, focusing on the renewable portfolio standard (RPS), evaluates alternative renewable energy policies. We propose a tractable equilibrium model which provides a structural representation of Korea's electricity market, including its energy settlement system and renewable energy certificate (REC) transactions. Arbitrage conditions are used to define the core value of REC prices to identify relevant competitive equilibrium conditions. The model considers R&D investments and learning effects that may affect the development of renewable energy technologies. The model is parameterized to represent the baseline scenario under the currently scheduled RPS reinforcement for a 20% share of renewable generation, and then simulated for alternative scenarios. The result shows that the reinforcement of the RPS leads to higher welfare compared to weakening it as well as repealing it, though there remains room to enhance welfare. It turns out that subsidies are welfare-inferior to the RPS due to financial burdens and that reducing nuclear power generation from the baseline yields lower welfare by worsening environmental externalities.

  • The rocking pier system (RPS) allows the columns to rock on beam or foundation surfaces during the attacks of a strong earthquake. Literatures have proved that seismic energy dissipated by the RPS through the column impact is limited. To enhance the energy dissipation capacity of a RPS bridge substructure, frictional hinge dampers (FHDs) were installed and evaluated by shaking table tests. The supplemental FHDs consist of two brass plates sandwiched by three steel plates. The strategy of self-centering design is to isolate the seismic energy by RPS at the columns and then dissipate the energy by FHDs at the bridge deck. Component tests of FHD were first conducted to verify the friction coefficient and dynamic characteristic of the FHDs. In total, 32 shaking table tests were conducted to investigate parameters such as wave forms of the earthquake (El Centro 1940 and Kobe 1995) and normal forces applied on the friction dampers. An analytical model was also proposed to compare with the tested damping of the bridge sub-structure with or without FHDs.

  • 2010년 민간 기업의 1,000 MW 규모 석탄 화력 발전소가 전력수급 기본계획에 최초로 반영된 이래로 이들이 해결해야 하는 가장 큰 난제는 RPS 제도 도입과 그에 따른 REC 공급의무이다. 만약 민간 석탄 발전소들이 REC 공급의무를 불이행하게 된다면, 막대한 과징금이 부과되기 때문에 이들의 전력생산 비용함수는 이를 반영하여 수정되어야 한다. 더 나아가 REC 공급의무는 발전량에 따라 결정되기 때문에, 민간 발전사업자가 자신의 REC 공급의무 이행능력이 부족하다고 판단할 경우 자체적으로 발전량을 감축하여 과징금을 낮추는 전략을 선택할 수 있다. 본 논문에서는 RPS 제도 도입에 따른 민간 석탄 발전소의 비용함수 변화와 이윤(수익) 극대화를 위하여 발전량을 감소시키는 메커니즘을 분석하였다.

  • This paper analyzes the environmental impact and economic effect of introducing the Renewable Portfolio Standard (RPS) into Korean electricity market using the DECADES (Database and Methodologies for Comparative Assessment of Different Energy Source for Electricity Generation) model, a comparative assessment tool developed by IAEA. A bottom up approach is adopted for the evaluation of air pollutant emission and its impact of several RPS scenarios. The environmental damage costs of RPS scenarios are evaluated based on the Extern-E results and Thailand externality study carried by EGA T. The results of this study can be applied in determining or analyzing the national electricity policy and energy policy.

  • For the dissemination of new and renewable energy, Korean government introduced a renewable portfolio standard (RPS) scheme in 2012 after terminating feed-in tariff (FIT) scheme that was introduced in 2004. With the RPS scheme, 64.7% of its own goal (95.7% in PV and 63.3% in non-PV) was achieved in 2012 and 67.2% of that (94.9% in PV, 65% in non-PV) was achieved in 2013. The deployment of PV systems met the goal very well and that of non-PV did not. Recently, Korean government revised the target year of supplying 10% electricity from new and renewable energy from 2022 to 2024 and released a couple of measures on PV area. Recent studies showed that the bankability of a project plays a key role for PV dissemination. Therefore, the dissemination should be assessed from the point of bankability under the RPS scheme and a little adjustment is necessary to achieve the goal. Especially, installing a small size PV (<100 kwp) system needs a minimum REC price or a FIT scheme. In non-PV area, permission process is a common bottleneck and the related regulation should be eased. In addition, to achieve the long term goal, an implementing scenario has to be prepared. Currently, the portion of the waste-gas energy originated from fossil fuel is too large among the new and renewable energy sources and the portion should be lowered or eliminated in the 10% of electricity supply goal. Seoul Metropolitan Government (SMG) has its own FIT scheme for PV dissemination from 2014 SMG and revised the PV tariff from 50 to 100 won/kwh in effective of 2015. It is worth to spread the other provinces.

  • Objectives : Retroperitoneal liposarcoma (RPS) is a rare solid tumor and has a high recurrence rate after surgery. New complementary and alternative medicine is required to manage symptoms of RPS and side effects of surgery, chemotherapy and radiation therapy. The purpose of this case report is to report two cases of reduction of side effects of surgery and radiation therapy in RPS treated with Wheel Balanced Therapy (WBT) which is a traditional Korean medicine treatment program for patients with cancer. Methods : Two patients with RPS were treated with WBT. Each of patients received personalized WBT schedule including acupuncture. The changes in clinical and laboratory findings were evaluated. Results : The symptoms of patients were improved after about 2 weeks hospitalization. Conclusions : This case report suggests that WBT has a potential to treat side effects of surgery and radiation therapy in patients with RPS. Further rigorous studies are necessary to investigate the therapeutic effects of WBT on RPS.
