摘要
对水电站多目标优化数学模型进行了深入的分析,在考虑水力发电多个约束的基础上,针对电站实际运行的特征,建立了发电量最大和用水量最小两个优化模型,分析了模型的目标函数和约束条件,用matlab求解了该多目标模型。并与采用其他方法的仿真结果进行比较,结果验明了该方法的有效性和实用性。
The multiple objective optimal mathematical model to hydropower plant is analyzed. On the basis of consider- ing several constrains, the characteristic operated actually to the hydroelectric power plants, sets up two optimal models, maximum generated electrical energy model and minimum water-consumption model, it analyses the goal function and the restraining terms to model, and using maflab to solve the multi-objective model. The experimental results show that this new method proposed is able to obtain higher quality solutions efficiently than the conventional approaches.
