Outline
In view of the fact that the reservoirs of medium and small hydropower stations usually operate at a lower level during the flood season because of the smaller regulating reservoir capacity, short decision time for flood regulation, maximum head of the unit and inundation limitation of the upstream reservoir area, etc., the flood resource utilization benefit is not fully utilized during the flood season regardless of the magnitude of the flood. The multi-objective risk analysis model for flood operation and scheduling of medium and small hydropower reservoirs is established with the objective of maximizing the power generation benefit and minimizing the flood risk, and the solution method for the optimal flood level is given when the forecasted incoming flood flow is in different ranges. The results show that when the reservoir faces different levels of floods, the optimal operation level can be obtained by coordinating the benefits and risks to increase the power generation benefits during small floods and reduce the flood losses during large floods, which provides a reference for the flood operation and scheduling of medium and small hydropower reservoirs under changing environment.
