Analysis and Calculation Method of Steady-state Energy Flow in Multi-energy Network
A universal mathematical description and a unified energy flow calculation method suitable for different energy forms are the theoretical basis for the planning and operation of multi-energy networks. On the basis of constructing the three-dimensional topological diagram for the multi-energy network
this paper proposes a unified description for energy transfer
and constructs the energy transfer equations of branches in the multi-energy network by borrowing the concepts of intensity quantity and extensive quantity in thermodynamics. Taking the most common cylindrical transmission pipeline as an example
this paper derives the energy transfer processes of branches of the AC and DC power transmission
incompressible viscous fluid
compressible gas
heat conduction and fluid heat transfer
and then establishes a network equation describing extensive quantity conservation of nodes. The steady-state energy flows of the independent energy sub-networks and multi-energy network are solved by the Newton-Raphson method
and the calculation examples verify the feasibility of the proposed method and model.
