%X This dataset is based on historical flood process data in 2020, 2021, and 2024 to build an optimal dispatching model for the gates of the Three Gorges and Gezhouba cascade reservoirs, taking minimizing the maximum outflow flow and the number of gate adjustments as the objective functions, and considering constraints such as water balance constraints, reservoir water level constraints, outflow flow constraints, discharge constraints of water discharge facilities, discrete gate opening constraints, gate opening and closing sequence constraints. Using the deep reinforcement learning near-end policy optimization algorithm to solve the problem, combining the environmental interaction and the decision-making of the agent in the policy evaluation stage, selecting the decision-making process with the largest cumulative reward as the optimal gate operation plan under the corresponding inflow flow process. By continuously updating the strategy, gradually Optimize the optimal scheduling process and finally determine the outflow process of the Three Gorges and Gezhouba Dam, reservoir water level process, and gate operation plan. The formulated reservoir dispatching plan not only improves flood control capacity but also effectively reduces the number of gate openings and closures. Each excel data set contains 4 sheet files, which are the inflow (m³/s), discharge (m ³/s), water level (m) and opening (m³/s) of the Three Gorges and Gezhouba Reservoir in July and August 2020, September 2021 and July 2024, and the opening (m) of each gate (the left area of the second river, the middle area of the second river, the right area of the second river, the sand flushing of the large river, and the deep hole) data
