Optimization of gas-fired combined cooling heating and power coupled with ground-source heat pump system
摘要：
该系统是传统冷热电三联供与地源热泵并联系统的一种改进与发展。以常规空调系统为基准，利用全寿命周期成本节约率与一次能源节约率组成综合评价指标，基于遗传算法对该系统进行了优化配置。针对遗传算法在实际应用中的局限性，引入多种群遗传算法，就设备容量、临界启停值进行了分析论证，发现多种群遗传算法在解决多变量优化配置时较标准遗传算法更合理。分析了各项指标随优化变量变化的规律。
Abstract：
This is an improved and developed system of the traditional combined cooling, heating and power system (CCHP) coupled with ground-source heat pump. Based on the conventional air conditioning system, using a comprehensive evaluation indicator consisted of life cycle cost saving rate and primary energy saving ratio, optimizes the system based on the genetic algorithm. Aiming at the limitations of genetic algorithm in practical application, adopts a variety of genetic algorithm to analyse the device capacity and start-stop threshold. Finds that multi-group genetic algorithm is more reasonable than standard genetic algorithm in solving multi-variable optimization configuration. Analyses the variation law of each index with the optimal variables.
