【摘要】：为提高冷热电联供系统在不同负荷结构下的优化配置水平与综合运行效益,对计及蓄能装置的冷热电三联供系统的优化配置及运行进行了深入研究。基于以热定电、以电定热和多目标综合效益最优的3种运行模式,建立了综合考虑能源、经济和环境效益的多目标优化模型,利用遗传算法对系统设备容量和运行模式进行了优化。然后,分析了能源价格与引入蓄能装置对冷热电联供系统综合效益的影响。最后,基于某建筑负荷不同的冷电比和热电比对上述内容进行仿真分析,并以分供系统作为参照对象,给出了不同负荷结构下冷热电联供系统的最佳配置及最佳运行模式。优化结果表明,在大部分负荷结构下,冷热电联供系统采用多目标综合效益最优运行模式时各方面效益更好。
[Abstract]:In order to improve the optimal configuration level and comprehensive operation benefit of the combined cooling and heat power supply system under different load structures, the optimal configuration and operation of the combined cooling and heat power supply system with energy storage devices are studied in depth. Based on the three optimal operation modes of thermal power, electric heating and multi-objective comprehensive benefit, a multi-objective optimization model considering energy, economic and environmental benefits is established. Genetic algorithm is used to optimize the equipment capacity and operation mode of the system. Then, the influence of energy price and energy storage device on the comprehensive benefit of the combined cooling and heat supply system is analyzed. Finally, based on the cold / power ratio and the thermal power ratio of a certain building load, the above contents are simulated and analyzed, and the optimal configuration and operation mode of the combined cooling and heat supply system under different load structures are given by taking the power sharing system as the reference object. The optimization results show that under most load structures, the optimal operation mode of multi-objective comprehensive benefit is better for the combined cooling and heat supply system.
