Construction and Optimization of a Thermo-economic Cost Analysis Model for the Complex Energy Network

Abstract

Improving the energy use efficiency of the energy system is of great significance to the development of the national energy economy and the improvement of the national economic competitiveness. The existing domestic research on thermo-economic costs is insufficient. For example, there is no research on the allocation of thermo-economic costs and on the complex energy network with multiple energy outputs. Therefore, this paper reconstructs and optimizes the thermo-economic cost analysis model for the complex energy network. First, the thermo-economic cost model for each sub-network and that for each energy output of the complex energy network were established, and the structure block diagram of the distributed thermo-economic cost allocation model for the complex energy network was given. Then, a local-global decomposition optimization method was proposed for the complex energy network to achieve the thermo-economic optimization of the complex energy network. The experimental results proved the effectiveness of the proposed algorithm.
