Accelerated Newton-Raphson power flow

This paper introduces the Newton-like method of modifying the right-hand-side vector into the power flow solution. Based on this method, the accelerated Newton-Raphson (ANR) power flow algorithm is proposed. In the proposed algorithm, a constant Jacobian matrix in the correction equations is employed to reduce the computation burden, while the power mismatch vector is multiplied by a factor to guarantee the convergence. Case studies on different test systems under different loading levels are presented to show the accuracy and efficiency of the proposed power flow algorithm.
