摘要

In this work, a novel method to plan and optimize pathways mix of urban regional energy system is proposed. A general model with vertices, paths and network balance as the elements is established, the digraph is used to describe the energy conversion and management process visually. Then, the matrices describing the characteristics of the energy network are developed. Basing on it, the objective function corresponding to the energy conversion paths is assigned as the weight, in order to make a comparison of system performance of different pathways mix. Furthermore, a case study of cogeneration system is evaluated by using the developed mathematical model. The results reveal the energy saving characteristics in different scenarios, further illustrating the applicable conditions and optimal strategies of distributed energy system. It is indicated that the proposed methodology have the ability to ameliorate energy network at the process of new-built planning and built areas reconstruction.
