It will be included in the next MATPOWER release (planned to be 8.0). But, if you want to use the updated version now, you can either … 1) clone/download and install the current MATPOWER master branch<https://github.com/MATPOWER/matpower> (to download, click the green “Code” button, then select “Download ZIP”), or 2) download the latest radial_pf.m<https://github.com/MATPOWER/matpower/blob/master/lib/radial_pf.m> (and t/t_pf_radial.m<https://github.com/MATPOWER/matpower/blob/master/lib/t/t_pf_radial.m>) and replace the corresponding files in your current MATPOWER 7.1 distribution.

Will it be integrated into MATPOWER 7.1, or do we need to download the updated radial.pf<http://radial.pf/> separately?

As long is the method converges with success = 1, the result should be valid. Also, if the Newton power flow converges, its result should also be fine. Sometimes the Newton power flow has more difficulty on distribution systems, but it depends on the case.

Sir, when we use this data for the generator matrix, it gets solved using Newton's Power Flow but gives this error: MATPOWER Version 7.1, 08-Oct-2020 -- AC Power Flow (Power Summation) Warning: Matrix is singular to working precision. > In calc_v_pq_sum (line 53) In radial_pf (line 63) In runpf (line 283) In Code (line 118) Power summation did not converge in 20 iterations when using the Forward-Backward Sweep method. I have considered the case33bw distribution network. Shouldn't the Forward-Backward Sweep method be better able to solve this network, considering it is a distribution network? Or is Newton's Power Flow modified to accurately solve radial networks as well? <image.png>
