摘要
能源互联网在资源禀赋、运行调度、效益需求、能量管理等多要素驱使下产生多维度的分层现象,在考虑下层园区与上层区域能源互联网需求互动背景下,首先提出典型下层园区与上层区域能源互联网需求互动分层基础结构,阐述了分层能源互联网结构中多能源生产、转换、传输、分配、消费系统的基本流程;然后,针对下层园区能源互联网高能效运行需求、上层区域能源互联网高经济运行需求,分别对应提出下层园区能源互联网火用效率能效动态协同优化运行模型、上层区域能源互联网经济动态协同优化运行模型;其次,将火用效率能效、经济多目标优化问题映射到合作博弈策略中,并分别设置各个单目标为合作博弈的参与方,进而提出基于合作博弈的分层协同优化求解方法;最后,通过算例分析对比验证了下层园区与上层区域能源互联网需求互动的动态协同优化运行分析模型及方法的合理性、有效性。
In view of multi-dimensional stratification phenomenon of energy internet driven by resource endowment, operation scheduling, benefit demand, energy management and other factors, this paper firstly proposes a basic framework of interaction demand between typical lower-level community and upper-level regional energy internet under the background of interaction demand between lower-level community and upper-level regional energy internet. Basic process of multi-energy production, conversion, transmission, distribution and consumption system in the hierarchical energy internet structure was described. Secondly, according to the high energy efficiency operation needs of lower-level community energy internet and the high economic operation needs of upper-level regional energy internet, it proposed the exergy energy efficiency dynamic cooperative optimization and operation model of lower-level community energy internet and the economy dynamic cooperative optimization and operation model of upper-level regional energy internet. Then, exergy energy efficiency and economic multi-objective cooperative optimization dispatch problem were mapped into the cooperative game strategy, and each single objective was set as the participants of cooperative game, and then a solution method of hierarchical cooperative optimization based on cooperative game was proposed. Finally, detailed example analysis and comparison verified the rationality and effectiveness of dynamic cooperative optimization and operation analysis of interaction demand between community energy internet and regional energy internet model and method.
