基于能耗和效益最优的发电权节能降耗分析

发电权交易对实施节能调度具有重要意义。为了从能耗角度对发电权交易进行分析，提出了煤耗率这一新的交易变量。文中以效益最优的发电权交易模型为基础，引入煤耗率这一参数，提出了基于能耗最优的发电权交易模型。结合效益最优模型和能耗最优模型，提出了二者的加权最优模型。该模型以上海电网为例，探讨了不同加权因子对节能降耗的影响。计算结果表明，发电权交易能减少煤耗，增加社会效益。

Analysis of Generation Rights Trade Based on Optimization of Energy-saving and Efficiency

The generation rights trade has important significance to implement energy-saving dispatching.In order to analyze the generation rights trade from the prospective of coal consumption,a variable called coal consumption rate is defined.With this variable,based on the optimal efficiency of trade model,a trade model for the optimization of energy consumption is proposed.Combined with the optimal model of efficiency and coal consumption,a weighted-optimal-model is proposed as well.For the objective of energy-saving,the influences of the models with different weighted factors are discussed in the Shanghai Power Grid.The results of case study show that the generation rights trade can reduce coal consumption and increase social efficiency as well.
