Abstract This paper presents a linear mixed-integer formulation to solve the short-term hydropower unit commitment problem. It uses the pair of maximum efficiency points of water discharge and the power produced at the maximum storage for all possible combinations of turbines. The goal is to maximize total energy production for all periods. The objective function is calculated using the correction between the power produced at the current volume and the maximum storage and penalizes unit start-ups. Constraints on the maximum number of turbine changes are imposed to find a viable solution. Computational results are reported for 65 instances with two powerhouses of five turbines each located in the Saguenay-Lac-St-Jean region of the province of Quebec in Canada.

使用效率点在短期水电机组承诺中最大化发电量的优化模型

摘要 本文提出了一种线性混合整数公式来解决短期水电机组承诺问题。它为所有可能的涡轮机组合使用一对最大的排水效率点和在最大存储处产生的功率。目标是最大限度地提高所有时期的总能源产量。目标函数是使用当前体积产生的功率与最大存储量之间的校正来计算的，并惩罚单元启动。为了找到可行的解决方案，对最大涡轮机更改次数施加了限制。报告了 65 个实例的计算结果，其中两个发电站有五个涡轮机，每个发电站位于加拿大魁北克省的 Saguenay-Lac-St-Jean 地区。
