Abstract
According to the different characteristics of distributed generation(DG)connected to distribution network,this pa?per divides DG into PV,PQ,PQ(V)three different node types,and constructs an equivalent model for power flow analysis of grid-connected distribution network. The forward and backward substitution algorithm is improved by using the superposition princi?ple,and is applied to solve the power flow analysis problem of the distribution system of weak loop network. Pure radial network can be solved by forward and backward substitution method. The voltage of each node can be calculated by adding the current of each loop and the corresponding branch current according to the superposition theorem. The experimental results of IEEE-33 distribution network show that the improved forward-backward algorithm based on superposition principle can obtain better convergence effect.关键词
