摘要: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.
