1 主要内容
该程序复现《A Modified Binary PSO to solve the Thermal Unit Commitment Problem》第五章内容，主要做的是一个考虑需求响应的机组组合问题，首先构建了机组组合问题的基本模型，在此基础上，进一步考虑负荷侧管理，也就是需求响应，在调控过程中通过补偿引导负荷侧积极进行需求响应，在模型的求解上，采用了一种基于改进二进制粒子群算法的求解方法，相较于传统的粒子群算法，更加创新，而且求解的效果更好，代码出图效果非常好。该程序函数比较多，主函数为Swarm_generator，运行结果已经保存在Graphs文件夹内部，可以通过运行Graphs.m直接得到出图结果。程序采用matlab编程，注释为英文，适合具有编程经验的同学下载学习！
