In this paper we present two new algorithms for solving the power flow equation. The algorithms are modifications of the BX and XB algorithms, obtained by explicitly treating lines with “high” r/x ratios. An analytical justification of the algorithm is given together with test results comparing the performance of the new algorithms with that of the Newton algorithm, the constant Jacobian Quasi-Newton algorithm and the BX and XB algorithms. The test results indicate that the new algorithms have greatly increased robustness properties over the BX and XB algorithms.
