In order to make the power flow calculation with small impedance branches converge smoothly, on the basis of analyzing the influence of the small impedance branches on solar Newton power flow calculation, combining with the characteristics of power network, a method based on compensation method was proposed to solve the power flow of systems with small impedance branches. Before the power flow calculation, this method compensates the small impedance branches which affected the convergence of power flow calculation, and the small impedance branches were equivalent to two normal impedance branches, so that the influence of small impedance branches was eliminated, and the power flow calculation could converge reliably. Theoretical analysis and numerical examples show that the proposed method can solve the convergence problem of power flow calculation when Newton method is used to calculate the system with small impedance branches.
