基于图论的城市能源规划方法 Urban Energy Planning Method Based on Graph Theory
2017
本文基于图论思想,提出了一种可较好地解决多源多汇多路径的城市能源系统的规划问题的方法。此方法的主要内容是通过建立能流网络通用模型,定义目标函数(碳排放指标)并将能量的转化路径对应的碳排放当量系数作为权重赋值,对能源系统供需路径进行组合优化。此方法有利于促进构建以绿色低碳、可再生能源为代表的现代能源体系,为特大城市或城市群的能源系统规划和优化提供思路。 Based on the idea of graph theory, this paper proposes a method to solve the planning problem of urban energy system with multi-source and multi-path. The main content of this method is to optimize the supply and demand path of the energy system by establishing a general model of the energy flow network, defining the objective function (carbon emission indicator) and assigning the carbon emission equivalent coefficient corresponding to the energy conversion path as the weight to optimize the supply and demand path of the energy system. This method is conducive to promoting the construction of a modern energy system represented by green, low-carbon and renewable energy, and provides ideas for the planning and optimization of energy systems in mega-cities or urban agglomerations.
