Study on Optimal Operation of Inter-Basin Water Transfer Project Considering Uncertainty of Hydrological Forecast based on Multi-Objective Optimization Method

Abstract

The shortage of water resources has become an important factor restricting economic and social development, and optimizing the inter-basin water transfer project is the key to solve the shortage of water resources. The purpose of this paper is to study the optimal operation of inter-basin water transfer project based on multi-objective optimization method considering the uncertainty of hydrological forecast. In this paper, a multiple linear regression algorithm is proposed. Based on this study, the experimental results of optimal operation of interbasin water transfer projects based on the uncertainty of hydrological forecast are analyzed. The experimental results in this paper show that the overall change of the forecast optimal dispatch chart considering the uncertainty of hydrological forecast is similar to the traditional optimal dispatch chart, the difference is that it incorporates hydrological data into the forecast, so that the current available water can be more accurately grasped. Therefore, in the flood season, the division of the guaranteed output area and the increased output area is clearer and more reasonable. Moreover, the forecast optimization dispatching chart considering the uncertainty of hydrological forecast can effectively improve the calculation of guarantee rate, which is of great significance to solve the urban water supply problem.
