Claim:
1. A method for a three phase power flow analysis of an unbalanced power distribution system based on a current injection mismatch equation of a nodal current mismatch over a nodal voltage change and an nodal admittance matrix, wherein the nodal admittance matrix includes a real part represented by a conductance matrix and an imaginary part represented by a susceptance matrix, comprising: determining, based on the current injection mismatch equation, a first voltage change corresponding to the conductance matrix; determining, based on the current injection mismatch equation, a second voltage change corresponding to the susceptance matrix; determining the nodal voltage change as a combination of the first voltage change and the second voltage change; and updating, using at least one voltage regulation device, voltages on three phases of the power distribution system based on the nodal voltage change to balance the voltages on three phases of at least some buses of the power distribution system, wherein at least some steps of the method are performed by a processor.
