Unbalanced three-phase distribution system load-flow studies including induction machines

This panel discussion summarizes some steady-state distribution systems studies based on the four-conductor current injection method - FCIM - power flow. This method 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. The method can include neutral currents and voltages. This summary intends to discuss simulation results obtained with some IEEE distribution test feeders
