本文针对当前科技水平不足以有效存储电力的情况下产生的发电机机组组合的问题，考虑负荷平衡、输电线传输容量限制等实际情况产生的约束条件，建立机组组合优化模型，追求发电成本最小。同时采用矩阵实数编码遗传算法（MRCGA）和穷举搜索算法，利用MATLAB 7.0.1和C++编程，分别对模型进行求解，并对所得结果进行分析比较，以此来帮助电力部门制定机组启停计划(This article in view of the current level of science and technology would not effective storage power generator unit combination problem, considering the load balance, such as transmission line transmission capacity, the actual situation of constraint conditions, unit combination optimization model is set up, the pursuit of power generation cost minimum. At the same time using matrix real-coded genetic algorithm (MRCGA) and exhaustive search algorithm, using MATLAB 7.0.1 and c++ programming, the model is solved respectively, and analyzes and compares the results to help power unit start-stop planning department)
