基于改进北方苍鹰算法的冷热电联供型微电网优化调度
摘要
为了实现冷热电联供(combined cooling
heat and power,CCHP)型微电网的经济运行,以综合成本最小为目标函数构建了CCHP型微电网优化调度模型。利用佳点集初始化和柯西高斯变异两种方法对北方苍鹰优化算法(northern goshawk optimization,NGO)进行改进,得到了寻优性能更强的改进北方苍鹰优化算法(improved northern goshawk optimization,INGO)。采用INGO算法对CCHP型微电网优化调度模型进行求解,算例分析结果表明,INGO算法求解的最小综合成本为10 835.94元,计算时间为7.75 s,在求解精度和计算时间方面优于其他对比算法。根据INGO算法获得的调度方案,系统内各设备出力合理,既保证了清洁能源的充分利用,也提高了CCHP型微电网运行经济性。
