摘要
传统能源系统互相独立、欠缺联动,容易导致能量的浪费,并且能源结构也难以优化。区域综合能源系统具备多能互补、高效利用的优点,是提高能源利用效率和环保性的重要改进技术。为了利用垃圾蕴含的能量和电动汽车负载端的能源消纳,文中建立一个考虑垃圾焚烧和电动汽车负载的区域综合能源系统模型,利用模型进行系统的优化调度研究。论文分析了系统内的多能源能量流通关系,而后对系统内的各种能源转换设备及电动汽车进行分析,引入垃圾能源化处理,将热能转化为电能,并利用电动汽车进行电能消纳的模式,得出区域综合能源系统的能源效益最大化的模型。通过python进行算例分析,结果表明,含垃圾处理和电动汽车参与的区域综合能源系统既能提高能源的利用效率,又能带来更优的经济效益。
Traditional energy systems are independent of each other and lack of linkage,which easily leads to energy waste,and it is difficult to optimize the energy structure.Regional integrated energy system has the advantages of multienergy complementation and efficient utilization,which is an important improvement technology to improve energy utilization efficiency and environmental protection.In order to take advantage of the energy contained in garbage and the energy consumption at the load end of electric vehicles,a regional comprehensive energy system model considering garbage incineration and electric vehicle load is established in this paper.The model is used to study the optimal scheduling of the system.The energy circulation relationship of multiple energy sources in the system is analyzed,and then,various energy conversion equipments and electric vehicles in the system are analyzed.Waste energy treatment is introduced to convert heat energy into electric energy,and electric vehicles are used to consume electric energy,so as to obtain a model for maximizing the energy efficiency of the regional integrated energy system.An example is analyzed by python,and the results show that the regional integrated energy system involving waste treatment and electric vehicles can not only improve the energy utilization efficiency,but also bring better economic benefits.
