Abstract
With a large number of distributed generation (DG) and controllable load connected to the power grid under the background of energy Internet development, the security and stability of the grid are challenged. Power flow control has become a problem of the operation of the power grid. Power flow router (PFR) has become an important element of energy Internet. It is an effective way to realize the power flow control of active distribution network when abundant distributed resources are connected to the grid. In this paper, the steady-state and dynamic operation characteristics of PFR are studied, and the corresponding mathematical model is established. The effect of PFR on optimizing the power flow and improving the dynamic characteristics of distribution network is analysed by the 14-node distribution network case simulating.

Summary
Under the background that energy Internet has become a hot topic in the field of energy research and construction at home and abroad, abundant distributed generations (DGs) and controllable loads are incorporated into the distribution network, which challenges the security and stability of the operation of the distribution network. A multi-port PFR is proposed in [2], which can dynamically control the energy flow. A general model of PFR integrated with power flow controller, various power and load interface devices and communication devices is proposed in [5] and [6]. In [8] and [9], a Y-type PFR based on three port isolated DC / DC converter is proposed, which uses phase-shifting technology to control the power flow in open-loop, but lacks certain generality. The routing and trading center adopts the transaction optimization strategy based on graph theory, and selects the lowest network loss path without blocking through PFR for power transmission to maximize benefits and congestion management. The effect of PFR on optimizing the power flow and improving the dynamic characteristics of distribution network is analysed by the case simulating
