Abstract Aiming at the power generation risk problem caused by the uncertainty of predicted runoff in reservoir forecast operation, a dispatch rule considering the inflow forecast information is proposed. Taking the Three Gorges Reservoir as the research object, a RiverWare model based on the operation rule is constructed by using RiverWare software. In order to verify the effectiveness of the proposed rules, the actual(perfect forecast)inflow is taken as the input, and the regular operation results are compared with the optimized operation results. In addition, to explore the power generation benefit risk caused by the forecast uncertainty, based on the forecast deviation coefficient and the Monte Carlo method, multiple groups of forecast deviation coefficients are drawn to carry out regular rule dispatching, and the results of the rule dispatch under the perfect forecast are compared and analyzed. The result show that compared with the optimization, the generation loss of regular operation is small, and it can effectively meet the requirements of stable discharge of the reservoir.When the forecast deviation coefficients under the three typical inflow scenarios are within 0.05,0.20,and 0.05 respectively, it is basically consistent with the power generation under the perfect forecast, and the relative deviation can be controlled within 0.2%. The regulation rules proposed in this paper can reduce the difference in power generation caused by the uncertainty of forecast runoff to a certain extent. The research results can provide references for forecast dispatch rule in the actual production and operation of the reservoirs.
