在建立的分布式供能系统优化配置混合整数线性规划模型基础上增加了修正函数,用以考虑环境温度对燃气轮机性能的影响。在不同能源价格体系下考虑环境温度的影响,对某燃气轮机分布式供能系统进行优化配置研究。计算结果表明:环境温度对系统的经济性和能源消耗影响显著,考虑环境温度影响后,系统年运行能耗费用和年总费用分别增加2.4%和1.8%,天然气年耗量增加10.3%,年购电总量减少8.4%;在不同能源价格体系下,环境温度对系统优化配置的影响程度不同,在一定的能源价格体系下影响比较显著;采用典型日各自的环境温度平均值与逐时考虑环境温度的优化配置结果基本一致。
A modified function was added based on the mixed-integer linear programming model of distributed energy system to optimize the gas turbine performance. Considering the influence of ambient temperature under different energy price system, the distributive energy distribution system of a gas turbine is optimally studied. The calculation results show that the ambient temperature has a significant impact on the economy and energy consumption of the system. Taking into account the impact of ambient temperature, annual energy consumption and annual total cost of the system increase by 2.4% and 1.8% respectively, and annual natural gas consumption by 10.3%. The total purchase of electricity decreased by 8.4%; under different energy price system, the impact of ambient temperature on the system optimal allocation is different, and under a certain energy price system, the impact is significant; using the typical ambient temperature average and the hourly consideration Optimized ambient temperature configuration results are basically the same.
