Research on the Water Storage Operation Model of Reservoirs Considering the Impact of Water Delay Time
Aiming at the problem of water delay time in the optimal scheduling of reservoirs， which leads to unbalanced water volume in the long-term scheduling and lagging of reservoir storage， based on the difference in the impact of water delay time on the optimization of water storage and the optimization of power generation. For analysis， the adjustment calculation method only considers the impact of the water delay time caused by the outflow of the adjacent upper reservoir， and proposes a reservoir group storage optimization scheduling model considering the water delay time. Combined with the stepwise optimization method， the model is solved in blocks， and the reservoir with beneficial conditions in the Anzhao New River Basin are selected as examples to verify the effectiveness of the model. The results show that this model meets the water storage demand of the reservoir， reflects the water storage benefit affected by the water delay time， and exerts the water storage potential of the reservoir group under the premise of ensuring the safety of operation.
