Abstract

Hydropower dams in Korea were built for power generation at the time of construction, but they have been operated with the additional purposes of supplying water, controlling floods, and environmental improvement through an agreement with the Han River Flood Control Office. However, these operations will result in losses of power generation, and may adversely affect the energy utilization. Therefore, it is the time to re-evaluate diversification of the dam operation method. In this study, the concept of resilience is introduced to evaluate the multi-function of hydropower dams. The resilience of the hydropower dams was defined as the recovery capacity of the dam water level, and framework was proposed to evaluate water supply and flood control performance. The applicability of resilience in hydropower dam was reviewed as a simulation result using historical data. In the future, if the economic feasibility of the dam performance such as power generation, water supply, flood control, and environmental improvement is evaluated, it can be utilized in establishing the operation standards for hydropower dams in line with the policy.

국내 발전용댐은 건설 당시 발전을 목적으로 지어졌으나, 최근 한강홍수통제소와 협약을 통해 일부 용수공급, 홍수조절, 환경개선 등을 부가목적으로 운영되고 있다. 그러나 이러한 운영은 주목적인 발전량에 손실을 가져올 것으로 예상되므로, 에너지 활용 측면에서도 부정적 영향을 끼칠 수 있다. 따라서 현시점이 운영방식에 대한 다각적인 측면의 재평가가 필요한 시점이며, 본 연구에서는 회복탄력성 개념을 도입하여 발전용댐의 다양한 성능을 평가하고자 한다. 댐의 수위 회복력을 발전용댐의 회복탄력성으로 정의하였고 이·치수 성능을 평가하기 위한 회복탄력성 프레임워크를 제시하였다. 과거 유입량 자료를 활용한 댐 모의운영 결과로 적용가능성을 검토하였다. 향후 발전, 환경개선, 홍수조절 등 수자원 활용에 대한 경제성 평가가 병행된다면 변화된 정책에서의 발전용댐 운영 기준을 수립하는데 활용 가능할 것으로 판단된다.
