摘　　要：为落实国家能源产业政策,电力行业提出了在安全约束下集节能、环保、经济为一体的多目标优化调度。在传统的AGC(自动发电控制)机组组合模型中,建立新的目标函数,在达到降低污染排放指标的前提下使发电成本最低,以达到节能减排调度的目的。通过引入排放成本系数和调度权重因子,利用动态规划法的前向算法建立递推方程解模型。对比分析三种不同优化目标的计算结果,表明所建模型能较好的实现经济指标和节能减排指标的相互协调,对火电AGC机组优化调度有一定指导作用。To implement the national energy policies,power industry proposes a multi-objective optimization of integrating energy saving,environmental protection and economic for the scheduling under the security constraints.In the traditional model of AGC(Automatic Generation Control) UC(unit commitment),a new objective function was built,under dropping of pollutant discharge,the function minimized the generating cost with the purpose of saving and pollutant reduction dispatching.Through the introduction of coefficient of emission cost and factor of schedule weight,it establishes recursion equation to solve the model by the use of forward algorithm of dynamic programming.Finally,by analysis the results of the three different optimization objectives,the coordination between economy and pollutant reduction are achieved through the model,it can be used to guide the thermal AGC UC optimization.
