【摘要】：采用線性混合整數(shù)規(guī)劃(MILP)方法研究水電系統(tǒng)短期優(yōu)化調(diào)度問題成為國際學(xué)術(shù)界的新潮流,其研究難點在于調(diào)度模型中非線性因素的線性化方法設(shè)計。在模型分析的基礎(chǔ)上,針對含抽水蓄能機(jī)組的梯級水電系統(tǒng)中存在的主要復(fù)雜約束,如非線性水電轉(zhuǎn)換關(guān)系、最小開關(guān)機(jī)時間、抽蓄機(jī)組特性、水流延時等約束,提出相應(yīng)的線性化方法及約束轉(zhuǎn)換方案,解決了模型轉(zhuǎn)化的研究難題。測試結(jié)果表明,文中提出的系統(tǒng)化方法具有普適性,適應(yīng)于各種模型中類似的非線性因素線性化及相應(yīng)的約束處理,方法有效實用,可靈活地拓展到其他調(diào)度領(lǐng)域。
[Abstract]:Using linear mixed integer programming (MILP) to study short-term optimal scheduling of hydropower systems has become a new trend in international academic circles. The difficulty of the research is the linearization design of nonlinear factors in scheduling model. On the basis of model analysis, the main complex constraints in cascade hydropower system with pumped storage unit, such as nonlinear hydropower conversion relationship, minimum switching time, characteristics of pumped storage unit, flow delay and so on, are analyzed. The corresponding linearization method and constraint conversion scheme are proposed to solve the problem of model transformation. The test results show that the proposed systematic method is universal and suitable for linearization of similar nonlinear factors and corresponding constraints in various models. The method is effective and practical and can be flexibly extended to other scheduling fields.
