Currently, the RPS(Renewable Portfolio Standard) is the policy which supplies new and renewable energy. Power generation companies with large capacity should produce renewable energy or secure through the purchase of REC (Renewable Energy Certificates) as mandatory. The government has revised the REC weight several times, which weights each energy source by evaluating the economic and social value of renewable energy sources, and revised the mandatory supply ratio to gradually increase. This study helps to find the impact of policies on related industries. In this study, time-series analysis and regression analysis on the capacity of PV(Photovoltaics) facilities as a dependent variable were performed to analyze the effect of the revision of the REC weight for photovoltaic power generation and the amount of mandatory supply for renewable energy. As a result, it was statistically assessed that the revision of the REC weight and the increase in the mandatory supply has a significant effect on the increase in the amount of PV facilities.

The primary purpose of Renewable Portfolio Standard (RPS) is to facilitate investment in renewable energy technology. Since emission trading program has similar purpose, it is conceivable to attempt to link RPS and emission trading program through interlinked markets. RPS in Korea with single REC and emission allowance markets has particular advantages for constructing linkages between two markets. This paper provides a real option model to examine investment effects of linkage of RPS to the trading program. Emission permit price and REC price are assumed to follow stochastic processes and renewable investment is irreversible. The result shows that linked market provides further incentive for renewable investment by raising managerial flexibility for power companies.

대표적인 신$\cdot$재생에너지의 시장확대 정책으로 RPS와 기준가격의무구매제가 주요 선진국에서 실시되고 있으며 자국의 자원부존과 경제사회여건에 맞춰 적합한 정책수단을 선택하고 있음. RPS 실시국가에서 RPS는 특별법으로 제정되어 실시효과를 극대화하고 있으며, 신$\cdot$재생에너지발전 인중서의 거래를 포함시켜 시너지효과를 거두고 있음. RPS의 단일의 최적모델은 존재하지 않으며 기본설계와 세부사항은 각 국의 고유의 자원부존 여건 및 경제사회적 특징에 따라 달라짐. RPS의 국내도입이 전력시장과 국민경제에 미치는 영향은 그리 크지 않으며 외부효과를 감하면 편익을 초래함. 또한 수요조사결과 RPS에 대한 선호도가 비교적 높게 나타나며 산$\cdot$ 재생에너지발전의 시장확대 수단으로 높은 점수를 매기고 있음 그러나 RPS의 기본설계를 신중히 가져가야 할 것이며, 법제도 정비에 임해서는 기존에 실시되고 있는 기준가격우선구매제도(발전차액보전)의 고려해야 함.

Recently, the government is actively promoting the RFS(Renewable Fuel Standards) and RPS(Renewable Portfolio Standards). Therefore, the importance of renewable energy fuel is being highlighted more than ever. Now is the time required active research in Korea. Since power bio-fuel oil demonstration project is underway dissemination to meet RPS quota. In this study, we investigated emission performance to make the performance standard draft of bio-fuel oil. In addition, the quality properties of the fuel oil and bio-oil, and after combustion in industrial boilers and compared the amount of exhaust gas. It was reduced emissions of bio-oil in industrial boilers due to bio-fuel properties as compare with fuel oil.

Generally, there are two types of regulation strategies for encouraging renewable energies ; regulation by quantity and price. With examples of quantity regulation, there RPS (Renewable portfolio standard) system in United States America, Renewable obligation in England, and MRET system in Australia. Countries that chose the price regulation are Germany, Spain, France, Portugal. This Paper overviews the current trends of regulation system on policies for renewable energies in foreign countries on these days.

At the moment, in Korea, over 90% of energy resources depend on imports, and nearly 60% of electric energy is produced using fossil fuel. Therefore, the government adopted the Climatic Change Convention and has implemented the RPS system since 2012 to actively cope with the dependence on imported energy, and to grow and expand the new renewable energy industry. This study examined the performance results of mandatory supply of solar photovoltaic energy and non-solar photovoltaic energy assigned to providers and the present state after implementation of the RPS system. As a result, the achievement rate in 2012 was 64.7%. Especially, solar photovoltaic energy showed a high achievement rate of 95.7%, whereas non-solar photovoltaic energy showed a low achievement rate of 63.3% due to several problems and was highly dependent on the government. In 2013, the burden of each provider has increased due to more mandatory supply and addition of unfulfilled supply of 2012, and the separate mandatory supply of solar photovoltaic energy established for protection of the solar photovoltaic market is restricting investment. Therefore, there is a need to assign mandatory supply in consideration of the available amount of each new renewable energy.

As Korean government has activated the renewable portfolio standard (RPS) since 2012, producers have been seeking and using the various renewable resources to meet the RPS quota. One of these efforts, Power Bio-Fuel oil demonstration project is being conducted to check the operability and compatibility with fossil fuel, Fuel oil (B-C) from 2014. The oil is a mixture of vegetable oil and animal fat or fatty acid ester of them and should satisfy some specification to use the power generation. The oil's quality and combustion characteristics are different from conventional oil, Fuel oil (B-C) in current power plant facility. In this study, it was investigated the storage stability and malodor intensity of Bio-Fuel oil.

Since the Renewable Portfolio Standard (RPS) would be started in 2012, the use of renewable energy should be 11% of total energy use including bio-fuel in 2030. The economic efficiency for renewable energy in B power plant was considered with the bio-diesel, wind power and solar power. The Net Present Value (NPV) and Benefit/Cost Ratio(BC) were used for the economic efficiency with the cost and benefit analysis. In case of bio-diesel, the cost resulted from the fuel conversion and the benefit would be created with trade and environmental improvement. With regard to wind power and solar power, the construction cost would be required and benefit factors would be same as the bio-diesel. The wind power was the best of economic efficiency of renewable energy as the results of NPV and BC ratio. Whereas, the market of wind power was very popular and the techniques of wind power has been developing rapidly.

While the policy intervention of each country for the promotion of renewable energy is strengthened, Korea introduced Feed-in Tariff (FIT) in 2002 to directly support the development of renewable energy. But in 2012, the shift of policy instrument that from FIT to Renewable Portfolio Standard (RPS) is occurred. This is a unique background that is currently found only in Korea, and new answers that focus on the outcomes of the shift of policy instruments are needed in addition to the existing discussion of comparison of FIT and RPS. Therefore, this study analyzed the change of policy efficiency after the shift to RPS using Data Envelopment Analysis(DEA) and Malmquist Index. In the result of analysis, a difference in the improvement of policy efficiency after in shift to RPS is found among each renewable energy source. This result is because renewable energy companies voluntarily entered the market only for energy sources that have secured technology or price competitiveness, and this indicates that the performance of renewable energy after the RPS shift has been concentrated on specific energy sources. As a result of this study, considering that the goal of renewable energy policy is to expand distribution and to drive growth engines, multi-faceted analysis is required in consideration of technology and market in selecting policy instruments.

In these days, many countries carry out many renewable energy policies to increase the renewable energy portion and to reduce the GHG(Green House Gas). In Korea, RPS(Renewable Portfolio Standards) focused on over 500MW power producers is conducting. And they are using the bio-fuel oil to meet their RPS quota. The oil is a mixture of animal and vegetable fat or fatty acid ester of them and should satisfy some specifications to use the power generation such as viscosity, pour point, acid number. Depends on the raw materials, quality characteristics of power bio-fuel oil are changed. By adding the power bio-fuel oil, pour point, density, sulfur content and viscosity are decreased and acid number, iodine number, oxygen content are increased. In this study, we test the quality characteristic of power bio-fuel oil and the property changes by the blending ratio of power bio-fuel oil & conventional fuel oil.
