  • 구조개편 이후 전력수급계획 수립여건이 한전의 독점적 계책에서 사업자 건설의향으로 전환됨에 따라 신규설비 건설계획은 수익성 위주로 전환되었다. 이에 따라 본 논문에서는 기저선비(원자력, 석탄화력) 운전효율성 항상 차원에서 건설되던 양수설비의 적정 설비규모를 계통 공급신뢰도 측면, 에너지 이응 효율성 향상 측면, 전력시장에서의 경제성 측면에서 검토하여 최적전원구성(Best Fuel Mix) 유도론 위한 정책적 방향을 제시하였다.

  • Including the rolling black out in 2011, Korea has suffered from rapid increase of electricity consumption and demand forecasting failure for last five years. In addition, because of the Fukushima disaster, high fuel prices, and introduction of new generation sources such as renewables, the uncertainty on a power supply strategy increases. Consequently, a stable power supply becomes the new agenda and a revisino of strategy for new power generation sources is needed. In the light of this, we appraises the sixth basic plan for long term electricity demand and supply considering the changes of foreign and domestic conditions. We also simulate a strategy for the new power generation sources using a portfolio analysis method. As results, a diversity of power generation sources will increase and the share of renewable power generation will be surged on the assumptions of a cost reduction of renewable power sources and an increase of fuel costs. Particularly, on the range of a risk level(standard deviation) from 0.06 and 0.09, the efficient frontier has the most various power sources. Besides, the existing power plan is not efficient so that an improvement is needed. Lastly, the development of an electricity storage system and energy management system is necessary to make a stable and efficient power supply condition.
