Abstract

The application of conventional method for optimizing firm water supply and hydro-electric power generation has some limitation during abnormal or extreme drought periods. Hashimoto et al. (1982) suggested there risk evaluation criteria such as reliability, resilience, and vulnerability. These three criteria have been incorporated into a mixed-integer programming model for evaluating the possible performance of water- supply reservoir (Moy et al., 1986; Srinivasan et al., 1999). However, till now, these kind of researches have been conducted only for water-supply reservoir. Therefore there have been no other study for multi-purpose dam including hydro-electric power generation. This study presents an improved formulation of the previous model for evaluating a multi-purpose reservoir system operation considering water supply and hydro-electric power generation. The modified model was applied to the Daechung multi-purpose reservoir system in the Keum river basin to demonstrate the efficiency of the improved formulation.

이수목적 수량관리를 위한 보장수량과 수력발전 등을 고려한 최적화 기법은 이상가뭄 또는 특이 수문년을 포함하는 경우에는 적용에 한계가 있다. 이러한 관점에서 Hashimoto 등(1982)에 의해 제안된 물부족에 관련된 3가지 평가기준을 혼합정수계획법을 통해 최적화모형에 반영하기 위한 Moy 등(1986)과 Srinivasan 등(1999)에 의해 제시된 바 있다. 그러나 이들 연구는 용수공급용 단일 저수지에 대해 한정되어 발전을 포함하는 다목적댐에 적용할 수 있는 정식화 연구는 부진한 실정이다. 본 연구에서는 다목적댐의 용수공급 및 수력발전 최적화 문제에 위험도 평가기준을 도입하여 운영평가를 위한 정식화 형태를 개선하였으며, 개선된 모형을 금강수계 대청다목적댐에 적용하여 그 실효성을 평가하였다.
