Optimal Daily Operation of Cascade Hydropower Stations

Journal of Water Resources Research, 2014
采用以水定电和以电定水两种运行方式，分别以发电量最大和总耗水量最小为目标函数，建立了梯级水电站群日优化调度模型，并采用动态规划方法进行求解。使用梯级水电站群日发电资料和径流资料(2013年7月~12月)的应用检验结果表明，优化调度较实际调度提高发电量约0.67亿kW·h(增加11.54%)和减少耗水量0.26亿m3(减少−0.89%)，发电保证率由92%提高到100%，显著提高了水电站群的发电效益。Daily operation models for cascade hydropower stations were proposed and developed in this paper.
