摘要
探索优化运行策略和激励机制对分布式供能系统的影响是加快其应用推广,保障其充分发挥效能的重要内容之一。该文首先针对北方某地区办公型建筑和宾馆型建筑夏季负荷需求,构建了一套冷热电三联供(combining cooling,heating and power,CCHP)分布式能源系统三维和二维模型,考虑系统碳排放并引进碳税和电力回购(电力反向卖回电网),构建了以运行费用为目标的分布式能源系统和常规系统分析模型,分析了三维模型和二维模型的差异;并讨论了蓄能系统对分布式能源系统经济性的影响,得出该系统为宾馆型建筑和办公型建筑供能的最优策略;最后对影响分布式能源系统经济性的相关政策和激励进行分析,得出了分别针对办公型建筑和宾馆型建筑的分布式能源系统经济性的气价和碳税激励控制域。
Exploring the influence of the incentive mechanism on the distributed system is one of the important contents. This paper established a distributed energy system combining cooling,heating and power（CCHP） based on the summer load demand of an office building and a hotel building in northern area. It is modelled with the three-dimensional and two-dimensional of distributed system. The operating cost was selected as objective function,the model considered the carbon emissions,carbon tax and the electricity buy-back from on-site（the surplus electricity out of the CCHP system can be sold back to the grid when the generated power exceeds local demands）,and analyzed the difference of three-dimensional and two-dimensional model. Then,the influences of the energy storage on operating cost was discussed,the optimal energy supply strategy of distributed system for the office building and hotel building was reached respectively. Finally compared with the conventional power system,the economic influence of policy incentives for the distributed system was analyzed,and the incentive control domain of gas prices and carbon tax were reached. The results showed that the economy of distributed system is better for the office building and hotel building than that of separate system.
