摘要
冷热电三联供系统(combined cooling heating and power,CCHP)的经济性受多种因素影响,需要在设计阶段进行系统的配置优化和运行优化。以年总费用(ATC)最低为目标构建了CCHP系统配置优化模型,同时构建了运行优化模型以确定最佳的运行方案。这两个模型均包含大量的逐时线性规划(linear programming,LP)模型,而常规循环求解方法求解耗时较长。通过对逐时LP模型分段消元,并引入图解法求解,将常规方法中的迭代循环转换成矩阵代数运算,可大大提高求解效率。计算案例显示:运行优化模型的求解时间从常规方法的78.500s减少到了0.015s,配置优化模型的求解时间从3 338.000s缩短至0.760s。极短的求解时间有利于CCHP系统的多方案对比和敏感性分析。
