New method for the analysis of distribution networks

A new method is presented for the solution of load flow in radially operated distribution networks. The method is based on an electric equivalent and on the elimination of the voltage phase angle in the equations to be solved, which makes it possible to obtain the exact solution working only with voltage magnitudes. In this way, a simple and efficient method for the exact load flow solution for this type of network is obtained, allowing the modeling of voltage-dependent loads and the formulation of related problems like the radial load flow with voltage constraints. The method can easily be programmed and has good convergence characteristics, as shown by examples
