This paper describes retail cost through scenario in the ratio of CG(Centralized Generation) and DG(Decentralized Generation) that constructs new generation capacity in the future. it is not calculated for the supply, but for demand considering an advantage of DG. In the Korea Power System, retail cost that composed of construction, T&D, fuel, maintenance and environment shows macro-trend that power system planning through penetration for DG will be more significant.

With the advent of electric power systems moving to a deregulated retail electricity market environment, calculating distribution service tariffs has become a challenging theme for distribution industries and tariff regulators. As distribution business remains as a monopoly, it is necessary to be regulated. And as multiple distribution companies compete with each other, it would be efficient to adopt competition to the determination of distribution service tariffs. This paper proposes a method to calculate distribution service tariffs using yardstick regulation, which can lead to competition among multiple distribution companies. The proposed method takes into account not only recovering revenue requirements but also the advantages of the yardstick regulation based on long-term marginal costs of distribution network expansion algorithms. A computer simulation is carried out to illustrate effectiveness of the proposed method and it is estimated that the algorithm can be applied to compute the distribution service tariffs under retail electricity markets.

At present the electric power industry in Korea is going through a major restructuring process. The restructuring is motivated by a desire to reduce electricity supply costs, to attract new in-vestment in modern generation, transmission and distribution facilities, and to stimulate innovation in the wholesale production and the retail supply of electricity. The experience to date shows that restructuring of electric power industry in the US, however, is marred with a number of problematic market performances including unreasonably high prices at wholesale. This paper investigates the important role of Power Exchange for stabilizing electric power industry in transition by offering various financial products. These financial products are used for risk hedging by the market participants. The paper focuses on the risk hedging by an individual supplier and derives an explicit decision rule that incorporates the attitude towards the risks. In addition to providing the financial products for risk hedging by market participants, the Power Exchange plays another very important role of financial safeguard system. Because of its unique characteristics, the Power Exchange is well suited for financial surveillance where it performs the early detection of unsound financial (and to a large extent operational) practices on the part of any system users and protect the system integrity and the market participants from the consequences of a default in the clearing structure.

본 논문에서는 WADE Economic Model을 이용하여 분산형전원 구축 시나리오에 따른 우리나라 전력계통의 영향을 정량적으로 평가하였다. WADE Economic Mode 미래의 증가하는 전력수요량[kWh]을 충족시키기 위하여 고려대상기간 동안의 매 년도에 대한 판매전력량 부족분[kWh]을 산정하고 판매전력량 부족분[kWh] 만족시키기 위한 신설발전설비를 시나리오에 따라 CG(Centralized Generation)전원과 DE(Decentralized Energy)전원인 두 가지 그룹으로 조합하여 담당하게 된다. 이와 같이 산정된 미래의 신설설비계획[kW]및 발전량[kWh]을 근거로 발전설비 및 송배전설비 건설비[원], 설비운전유지비[원], 연료비[원], 환경비[원]를 계산하여 전력소매요금을 산정한다. 본 연구에서는 WADE Economic Mode의 적용을 위한 우리나라 실 데이터를 구축하고 이를 WADE Economic Model에 적용하여 우리나라 전력계통에 분산형전원을 투입 시 미치는 영향을 분석함으로서 향후 우리나라 전력수급기본계획의 수립에 필요한 유용한 정보를 도출하도록 하였다.
