Power flow solution by a complex admittance matrix method

The paper describes a newly developed algorithm for power flow solution based on a complex admittance matrix. The conciseness and close‐to‐reality iterative procedure make the method extremely attractive for self‐made software implementation. The complex algorithm approach enables network connections, loads, generators, controlled bus voltages, including slack bus, to be considered in a single complex matrix. The power flow solution is achieved with iterations in complex form without the need of real/imaginary decomposition. The method has shown to have advantages over other traditional and available methods in terms of accuracy and convergence also in highly ill‐conditioned cases. The cpu‐time is comparable and sometimes competitive with those derived from Newton‐Raphson methods.
