Optimal Reservoir Operation with Environmental Flows for Ranganadi Hydroelectric Project in Arunachal Pradesh
Abstract Optimal release policy for hydro power has been developed extensively in the past for several river basins in India and abroad. However, there is a lack of available literature which takes into account the optimal release along with the necessary environmental flow to the downstream side. As a consequence several hydropower projects are facing problem due to the environmental concerns. In Arunachal Pradesh, some of the hydropower projects are under critics basically due to environmental factors. In this study, a formulation has been developed to obtain the optimal release for hydropower for Ranganadi Hydro Electric Project (RHEP) in Arunachal Pradesh, considering the constraints of minimum environmental flow. Traditionally reservoirs used to be operated without considering the environmental flows. Whenever the release to the downstream side (or overflow) is to be considered, the flow exceeds the active storage capacity of the reservoir. In this study two models have been formulated, one considers the optimal release for hydropower without consideration of minimum environmental flow and the other with the consideration of environmental flows and have been solved using Lingo. Thus traditional optimal release policy has been compared with the condition of optimal release when minimum environmental flows are enforced at the downstream side of the reservoir. The minimum environmental flow has been obtained based on the practices being followed in India and the other parts of the world.
