Abstract :

Reservoir operation is one of the key issues among various water resources issues. In evaluating water resources planning projects, aspects of water supply for consumption needs and its environmental effects are usually considered, and among these, the effects of these projects on energy production in power plants are not considered. In this research, the effects of changing the control curve of Mahabad dam in the form of two scenarios of reservoir performance from the angle of hydropower generation in the dam (Mahabad) and meeting downstream needs are investigated. Planning scenarios include Scenario I (maintaining the reservoir volume of Mahabad Dam in drought and wet conditions in normal cultivar) and Scenario II (meeting the maximum needs of agriculture and hydropower generation) which was entered into the Hec-ResSim model for simulation. In this model, based on the information received from the Water Resources Management Company, the geometrical characteristics of the Mahabad Dam reservoir and the downstream consumer reforms of the Mahabad Dam and the environmental needs of the Mahabad River, the river system was drawn and entered as the Hec-ResSim simulator model. The model was implemented for a period of 29 years from 1991 to 1399 and the results showed the superiority of Scenario II over Scenario I, so that in the conditions of implementation of Scenario II, the supply of agricultural sector had increased from 30.7% to 63.3%. Scenario II Hydropower generation has increased from 38.1 MWh to 43.3 MWh.
