Abstract

In this study, the formulation of the developed mixed-integer programming model for a multi-reservoir system including hydro-electric power generation (park et al., 2001) has been improved for multiple reservoir system operation using risk evaluation criteria. Sequential linear programming(SLP) was applied for the linearization of the hydro-electric energy term in the model. In order to allocate monthly reservoir release reasonably the value of weight for hydro-electric energy was assigned by level of power generation hour. The improved model was applied to the five reservoirs system in the Han river. And could be confirmed the availibility of new formulation appling risk evaluation criteria.

위험도 평가기준을 발전함수를 고려하여 단일저수지에 적용한 박명기 등(2001)의 혼합정수계획법 모형을 다중저수지군 운영에 적합하도록 개선하였다. 본 모형중의 축차선형계획기법(SLP)은 목적함수중 수력발전함수의 선형화를 위하여 적용되었으며, 저수지 방류량의 합리적인 월별 방류배분을 위하여 수력발전량에 대한 가중치를 발전시간 수준별로 적용하도록 정식화요소에 반영하였다. 개선된 모형은 한강수계 5개 저수지군에 시험적용 하였으며, 수계내 연계운영을 위한 복합저수지군의 최적연계에 본 위험도 평가기준을 적용할수 있음을 확인할 수 있었다.
