A New Power Flow Method Solving DG Integrated Distribution System

With the fast developing on distributed generations (DGs) integrating into distribution system, it changes power flow direction in tree-topology, as a result of which traditional power flow method is not effective for this new scene. It is necessary to make improvement on traditional method in order to accelerate the speed of power flow calculation. Since fast decoupled method is not suitable for system with a high R/X ratio, its need to make compensation for the branches to increase R/X ratio. DGs are integrated into power gird normally by inverter interfaced mode or direct grid-connected mode. In this paper, a new fast decoupled power flow method is proposed which could solve various DGs integrated into distribution network, as well as loop topology of distribution system. The utility of proposed method is tested by simulations of IEEE 69-bus system.
