摘要:

针对地源热泵冬夏运行时长不均导致的土壤热失衡问题,提出考虑土壤排取热量平衡的区域综合能源系统优化调度方法。首先,根据地源热泵冬、夏季节运行特性,计算土壤年度排取热量不平衡率;其次,通过提高供冷季地源热泵使用时长以增加土壤排热量,确保地源热泵全年取排热量平衡;最后,构建了双层优化模型,上层模型以冬季系统运行成本最优,安排地源热泵出力,下层模型以系统夏季效益最优,考虑土壤取-排热量平衡等约束优化地源热泵出力。仿真算例表明所提方法有效解决了土壤热失衡问题,系统能效得到提高。

Abstract:

In order to solve the problem of soil heat imbalance caused by the uneven operation time of ground source heat pump in winter and summer, an optimal scheduling method of regional integrated energy system considering the balance of heat discharged from soil was proposed.First, according to the operating characteristics of ground source heat pump in winter and summer, the annual heat imbalance rate of soil is calculated.Secondly, increase the use time of ground source heat pump in the cooling season to increase the heat output from the soil, so as to ensure the heat balance of ground source heat pump throughout the year.Finally, a double-layer optimization model is constructed.The upper model optimally arranges the output of ground source heat pump based on the system operating cost in winter.The lower model optimizes the output of ground source heat pump based on the system’s optimal benefit in summer, taking into account constraints such as the soil heat extraction and emission balance.Simulation examples show that the proposed method effectively solves the problem of soil thermal imbalance and improves system energy efficiency.

Key words: soil thermal imbalance, ground source heat pump (GSHP), regional integrated energy system (RIES), optimal dispatch
