水电站经济运行的优化模型及其分解协调求解方法研究

考虑水电机组的出力约束、出力曲线及水库的水量平衡约束、库容约束、水头变化等因素,给出了水电站经济运行的约束条件。基于大系统原理,以水电站发电出力的耗水量最小为目标函数,建立了多机组、多时段水电站经济运行的优化模型。利用大系统分解协调算法,给出了优化模型的求解算法。

A Study on Optimization Model and Large Scale System Decomposition Coordination Method for Hydropower Station Economic Operation

The restrictions of hydropower station economic operation are given by taking several factors into account,such as the load restrictions,load curves of units and the water balance,capacity restricts,water head change and flow restrictions of pool.Then,aiming at minimizing water consumption of the hydropower station,the optimization model of hydropower station economic operation is set up based on the larger scale system theory,which describes operations of many units at varied period of times.At last,the computing algorithm of this model is showed in detail through combining large scale system decomposition-coordination method with dynamic programming method.
