Hi, I am trying to run a PF on a 154 bus system using Matpower and I am unable to get it converged. What I have tried so far is:
1. Increasing all the loads 2. Removing all generators and using only slack bus 3. then changing slack bus 4. trying different algorithms. Only in the algorithm of Newton Raphson I get a warning which says: Warning: Matrix is singular to working precision. > In newtonpf at 89 In runpf at 205 Kindly let me know, what should be my next course of action? Kind Regards, Waqas
