水电站群装机容量选择的双层优化数学模型

Two-stage Optimizing Model for Determining Installed Capacities of Hydropower Plant Groups

本文应用系统分析方法,探讨了电力系统中水电站群装机容量优化选择问题。在分析各类电站投资、运行费特性及其对系统总体经济性影响的基础上,提出了一种双层优化数学模型,即以系统计算费用最小为目标,对所有装机方案进行系统运行方式的优化,在此基础上,优选水电站群装机容量。文中还对模型的求解进行了探讨,并通过实例分析验证了模型的有效性。

In this paper,the determination of the Optimal installed capacity of a hydropower plant group in a power system is investigated using the system analysis method,and a two-stage optimizing model is proposed which com bines the determination of the installed capacity of the hydropower plant group with the optimization of the way of operation of the power system. The problem how to solve the model is dealt with and an example shows the suitability.
