摘要：
In order to solve the problem of multiple energy flow coupling relationship modeling in complex energy hub, a multiple energy flow coupling matrix modeling method based on graph theory was proposed. The equipment and energy flow in the energy hub was generalized as a node-branch binary relationship, the common virtual node and generalized loss energy flow branch were introduced, and the multiple energy flow balance network model of complex energy hub was built. Based on the path matrix theorem, a support tree construction method based on star network was proposed. By means of the sub-matrix of node branch association matrix and the equipment efficiency parameters, the multiple energy flow coupling matrix equation was established, and the non-singularity of the correlation matrix in Gaussian elimination process was proved. Compared with the existing matrix modeling methods, the proposed method can write the multiple energy flow coupling linear matrix equation with the least energy flow variables. The standardized data structure based on graph theory of the proposed method can be helpful to realize the automatic generation of multiple energy flow coupling matrix. The effectiveness of the proposed model and method can be verified by an example of optimal operation of multiple energy flow system connected by multiple energy hubs. © 2022 Chinese Society for Electrical Engineering.
