通过离子群优化算法(PSO)求解水电站优化调度模型,以主汛期运行水位和后汛期运行水位为协调变量,分析主汛期与后汛期运行水位变化对水库水量利用率、多年平均发电量及水库蓄满率的影响。表明主汛期和后汛期运行水位越高越好,而且,提高主汛期运行水位比提高后汛期运行水位对增加多年平均发电量更显著,主汛期运行水位比后汛期运行水位对水量利用率的影响也更明显。结果对研究水电站的效益与风险问题具有现实意义。
The optimal scheduling model of hydropower station was solved by ion swarm optimization (PSO) algorithm. Based on the operation water level in the main flood season and post-flood season as the coordinating variable, the influence of the change of operating water level in the main flood season and the later flood season on the reservoir water utilization efficiency, Full rate of impact. Which indicates that the higher the operating water level in the main flood season and the later flood season, the better. Moreover, increasing the operating water level in the main flood season is more significant than increasing the flood season operating water level to increase the multi-year average power generation. The impact of the main flood season operating water level over the late flood season operating water level on the water utilization rate Also more obvious. The results have practical significance for studying the benefit and risk of hydropower station.
