Abstract

The invention discloses a hydropower two-dimensional dispatching map constructing method based on coupling of runoff prediction information, relating to the technical field of reservoir dispatching. The method comprises a step of carrying out hydropower station two-dimensional dispatching map basic form generalization, a step of establishing a hydropower station two-dimensional dispatching map optimization model, a step of using a multi-objective genetic algorithm to carry out optimized composition on the generalization form of a hydropower station two-dimensional dispatching map based on the hydropower station two-dimensional dispatching map optimization model, and obtaining an optimized two-dimensional dispatching map, and a step of putting a runoff level probability into storage based on a prediction, and using a posterior probability weighted average method to calculate hydropower station decision-making output. According to the method, the short-term and long-term benefits of the reservoir can be effectively coordinated, the improvement of a hydropower station panoramic generating capacity is facilitated, at the same time, the decision-making output of the hydropower station is obtained based on the posterior probability weighted average method, the full consideration of the randomness of runoff is facilitated, the probability of a decision-making error is reduced, and the method is suitable for reservoir long-term power generation plan making and reservoir real-time scheduling.

Description

technical field [0001] The invention relates to the technical field of reservoir dispatching, in particular to a method for drawing and using a two-dimensional dispatching diagram of a hydropower station coupled with runoff forecast information. Background technique [0002] Reservoirs are an important engineering measure for humans to redistribute water resources in time and space, and reservoir scheduling technology is one of the necessary means to achieve normal and efficient operation of reservoirs. Using the storage capacity of the reservoir to optimize the distribution of water resources in time and space can improve the management and operation level of the reservoir, achieve the purpose of benefiting and eliminating harm, and can improve the utilization rate of water resources and water energy resources. Due to its simple and convenient operation, the hydropower station dispatching chart is an important tool in the existing reservoir dispatching technology to guide t...
