园区型综合能源系统节能效果及优化运行分析

Analysis of energy saving effect and optimal operation of park integrated energy system

随着综合能源系统在国内的快速发展,对综合能源系统际运行后的节能效果评价日趋重要。分析了园区型综合能源系统节能效果及其优化运行手段,该园区型综合能源系统包括光伏发电系统、地源热泵系统、太阳能空调系统、蓄热式电锅炉系统及太阳能热水系统等。建立了各子系统的节能效益计算模型,根据各子系统的运行历史数据,对各子系统的计算结果进行了分析。结果表明:太阳能光伏发电系统节能收益主要来自第二、第三季度,应在此期间注意光伏组件的维护保养,保证节能效益最大化;地源热泵系统夏季节能效果并不显著,在夏季可与传统机组协同供冷;园区冬季供热是由地源热泵系统、蓄热式电锅炉系统和太阳能空调系统综合提供,节能效果显著,是园区节能收益的主要来源。

With the rapid development of integrated energy system in China,the evaluation of energy saving effect of integrated energy system after actual operation is becoming more and more important.The energy saving effect and optimal operation of the integrated park type energy system are analyzed.The park integrated energy system includes photovoltaic power generation system,ground source heat pump system,solar air conditioning system,regenerative electric boiler system and solar hot water system and so on.The energy saving benefit calculation model of each subsystem is established,and according to the operation history data of each subsystem,the calculation results of each subsystem are analyzed.The result shows that the main revenue comes from the second and third quarters,during which it should pay attention to the maintenance of photovoltaic modules to ensure the maximum energy saving benefit.The energy saving effect is not significant.It can cooperate with traditional units for cooling in summer.The heating in winter in the park is provided by ground source heat pump system,regenerative electric boiler system and solar energy air conditioning system.Its energy saving benefit is the main source of energy saving income in the park,with remarkable energy saving effect.
