Hi Sir, I hope you are doing well. 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: image.png]
