As more and more new energy devices are connected to the power grid, the energy Internet with energy routers as nodes is an effective way to accept new energy access, which can realize the two-way flow of energy and effective control of power. In this paper, considering the influence of line resistance when multiple energy routers need mutual power to improve the stability of system operation, it analyzes the coordinated control strategy of the designed multi-energy routers running in an ideal case and the influence of line resistance on the effect of coordinated control strategy. Then improves the control strategy in order to eliminate the influence of the line resistance, and finally achieves the maximum utilization rate of new energy and the highest reliability of load power supply when multi-energy routers operate cooperatively. Aiming at the coordinated control strategy designed in this paper, the simulation verification is given at the end.
