Energy router based on power electronic technology is the core equipment of Energy Internet. Based on the structure of energy router in power grid

a steady-state calculation model for energy router is proposed

which is in account of multiple control modes and suitable for multiple operating environments. Then the AC-DC hybrid power flow calculation model with energy router is established

and the feasible solution of power flow is obtained by using the regulation of the energy router. The result verifies the correctness and effectiveness of power flow calculation model of energy router and method of obtaining feasible solution based on the improved IEEE 30 nodes system

which are suitable for the requirements of different control modes of energy router and the AC-DC active or passive network.
