摘要：

As the penetration of combined heat and power (CHP) units and renewable sources increases, the interaction between electrical and heating networks becomes tighter and modeling electrical and district heating networks as a whole becomes increasingly important. A linear programming-based optimal power flow model of combine heating and electrical system was proposed in this paper, which was not only applicable for radial network but for meshed network as well. The model of electrical and heating network as well as their linking components was established respectively by analyzing the topology of combined system. The basic matrix formulation of network equations was pursued for the linear optimal power flow model and the coefficient matrices can be modified rapidly according to different types of topology, which proved strong applicability. By transforming the nonlinear, non-convex problem to the linear programming problem, computational efficiency was improved greatly and potential convergence problem was avoided. One actual case was studied to show the accuracy and robustness of the proposed algorithm. © 2019 Chin. Soc. for Elec. Eng.
