摘要
综合能源系统能够实现能源的优化利用,有效提高能源使用效率,缓解环境污染问题。以往对于综合能源系统能源站规划的研究主要集中在设备容量的优化配置方面,较少对能源站位置及管网路径的优化规划进行分析。研究了考虑电、热供应的区域综合能源系统能源站选址及能源传输管网路径优化布局问题。首先,根据p-中位模型建立了能源站选址及管网路径布局的优化规划模型。其次,考虑能源站、管网设备初始投资及施工费用,建立了区域综合能源系统投资费用模型。最后,基于枚举法提出了一种改进求解方法对规划模型进行求解,并以某园区为实例进行仿真分析,验证了所提模型及方法的有效性。
The development of integrated energy systems(IES)can achieve the optimal use of energy,effectively improve the energy efficiency and mitigate the environmental pollution problems.The existing research on the energy station planning of IES mainly focused on the optimal configuration of equipment capacity,and less analysis of the optimal planning of energy station location and pipeline network path is performed.This paper aims at the problem of energy station location selection and optimization layout of energy transmission pipe network considering electricity and heat supply.Firstly,based on the p-median model,an optimal planning model for energy station location and pipe network path layout is established.Secondly,considering the initial investment and construction costs of energy stations and pipe network equipment,an investment cost model of regional integrated energy system is proposed.Finally,the planning model is solved by an algorithm based on the enumeration method.The validity of the model and the algorithm is verified through the simulation of an area.
