This paper describes about the rarely Newton Raphson formulation for solving the power flowproblem, consist of the injetion 2n current equation written on rectangular coordinate. The Jacobianmatrix has same structure such as admittance matrix knot (Zn x Zn), where each network branchrepresented by block (2 x 2). Execptable for PV bus. Diagonal-of block (2 x 2) from jacobian equationwas proposed as some in admittance matrix knot. The result indicate that the proposed methods forsolving the power flow is faster, its than the conventionally Newton Raphson formulation, expressed inimbalanced power condition which written in polar coordinate.
