Method for drawing up multi-goal reservoir optimization scheduling graph capable of being self-adaptive to climate change

Abstract

The invention discloses a method drawing up a multi-goal reservoir optimization scheduling graph capable of being self-adaptive to climate change. The method for drawing up the multi-goal reservoir optimization scheduling graph comprises the steps of: step 1. establishing a coupling model of a global climate model (GCM) and a variable infiltration capacity (VIC) hydrological model so as to forecast a run-off process under a future climate change scene; step two. establishing a multi-goal reservoir optimization scheduling graph model; and step 3. taking the forecast run-off process data under the future climate change scene as the input of the optimization scheduling graph model, and drawing up the multi-goal optimization scheduling graph model by adapting a self-adaptive genetic algorithm. The method for drawing up the multi-goal reservoir optimization scheduling graph has the advantages of balancing the social economy goal and ecological goal of reservoir scheduling, improving the comprehensive benefits of reservoir scheduling to the maximum degree on the condition of ensuring the flood control safety of a reservoir and being capable of being self-adaptive to future climate change and being widely applied to the production practice of multi-goal reservoir optimization scheduling.

Description

technical field [0001] The invention belongs to the technical field of reservoir optimal dispatching diagrams, in particular to a method for compiling a multi-objective optimal dispatching diagram of reservoirs adaptive to climate change. Background technique [0002] Reservoir scheduling diagrams have the advantages of intuition, convenience in application, and easy reflection of the time continuity of scheduling rules, and are widely used in production practice. According to whether the optimization method is used or not, the reservoir operation diagram can be divided into conventional operation diagram and optimized operation diagram. The existing reservoir optimal operation diagram has the following deficiencies: (1) it only pays attention to the social and economic functions of the reservoir, and strives to maximize economic benefits, ignoring the ecological water requirements of the downstream of the reservoir and the reservoir area; (2) the reservoir optimal operation...
