权衡供水与发电目标的水库调度建模及优化

以供水水库为研究对象,考虑了水库的供水、发电目标及两目标的权衡,构建了供水计算、发电计算和多目标计算等三个模型,并分别通过二次规划、混合整数线性规划、非线性规划对三个模型进行优化求解。研究涉及高维性、非线性、多目标在内的水库优化调度问题求解难点。以某两水库调度问题为例,应用优化软件LINGO高质高效求解,为以供水与发电作为主要目标的水库调度问题求解分析提供了示范。

Modeling and optimizing reservoir operation for trade2off between water supply and power generation objectives

This paper focuses on the optimal o per at ion o f a wat er supply reserv oir and considers both the wat er supply and pow er generatio n objectives and the tr ade2o ff betw een the tw o objectives. The water supply model, power pr oductio n model, and multi2 objective model are fo rmulat ed and so lved by quadratic pr og ramming , mixed integ er linear pro gr amming, and nonlinear pro gr am2 ming , r espectiv ely . The hig h2dimensional, nonlinear, and multi2o bjective difficulties inherent t o the o ptima l operation o f r eser vo ir sy stem are invo lv ed in this study . A two2reserv oir pr oblem is taken as a case study and r eso lv ed effect ively and efficiently using the o ptimizat ion so ftwar e LINGO. The st udy pr ov ides a demonst ratio n for r eservo ir operat ion w ith water supply and pow er gen2 er ation as the main objectives.
