基于多目标非线性规划模型计算的电厂负荷分配方案设计

Design of a Scheme for Distribution of Power Load Based on Multi-objective Multivariate Non-linear Planning Model

以某区域火电机组在各个时段的出力为决策变量,将经济支出和CO2排放总量最小作为目标函数,以电力系统平衡和机组出力限制为约束条件,建立多目标非线性优化模型;采用模糊层次分析法结合线性加权法将多目标规划转化为单目标规划;最后,利用LINGO软件求解出负荷分配的最优方案。

The decision variables for the regional thermal power unit are the generation loads in each period, the total economic costs and minimal CO2 emissions as the objective function, power system balance and unit output as restrictions. Set up nonlinear multi-objective optimization model on all above basis;Using a combination of linear weighting and fuzzy analytic hierarchy process （FAHP） method to transform multiobjective programming into a single objective programming;And finally take advantage of LINGO software to compute the optimal load distribution scheme.
