Study on Reservoir Optimal Operation Based on Dynamic Programming Method
The optimization of reservoir operation is affected by many factors,so it is necessary to optimize the reservoir system from a global perspective,after optimizing the dispatching scheme,the following conclusions are drawn:the optimal dispatching scheme has a better effect on the generation capacity in the year of abundant water,and the annual average difference between the conventional dispatching scheme and the optimal dispatching scheme is 288×104kW·h,the effect of the optimal dispatching scheme is the second,the difference between the two schemes is 209×104kW·h per year,and the effect of the optimal dispatching scheme is not significant,the annual average difference between the two is only 23×104kW·h,which shows that the optimal dispatching scheme based on the dynamic programming model is more effective in the high-water year,but less effective in the low-water year,the optimal dispatching scheme has little effect on the generation capacity.When the discharge is large,the increase of head loss is small.In order to improve the efficiency of power generation,the tail water level can be raised to increase the discharge and power generation,and to control the head loss.
