Abstract:According to NewtonRaphson(NR) method, a new power flow method based on reliable power flow technique is proposed.By introducing a pair of variables to each branch, the power equations of radial distribution networks become linear. By adding equations that reflect the relation of state variables, the power flow technique that is suitable for meshed distribution systems is formed and the practicability of the technique is enhanced greatly. The proposed method has been applied to several meshed distribution networks and the results show that our method is superior to conventional NR method both in terms of speed of convergence and computation times.
