A Comparative Study on the Performance of TCIM Full Newton versus Backward-Forward Power Flow Methods for Large Distribution Systems

Abstract

This panel discussion summarizes performance comparisons between the well-known backward-forward sweep and a Newton load-flow algorithm when applied to large scale three-phase distribution systems. The three-phase current injection method-TCIM, applies the full Newton method to solve the nonlinear current injection equations which are derived using phase coordinates, and the complex variables are written in rectangular form. This summary intends to discuss simulation results obtained using some practical large scale distribution systems
