Pandapower OPF does not converge with pp version > 2.2.0
Hello, I have some problems with pandapower after updating to a version higher 2.2.0. Same code, works fine on pandapower 2.2.0 but on version 2.3.0 or even 2.5.0 the "Optimal Power Flow did not converge!"
################################## example code ################################################# net = sb.get_simbench_net("1-MV-semiurb--0-sw") pp.create_sgen(net, bus=25,p_mw = 0,name = 'KWK', controllable = True,min_p_mw=0, max_p_mw=100, max_q_mvar = 0, min_q_mvar = 0, index = 1000) pp.create_poly_cost(net, 1000, 'gen', cp1_eur_per_mw=-1)
pp.runopp(net) ##############################################################################################
It would be great if you could help me. Thanks in advance!
Hello, I run into the same problem. The above-mentioned code works with pp 2.2.0. But I had to change the 'gen' to 'sgen' in the cost function. With pp >2.2.0 it does not converge like other simbench grids or the provided kerber grids. That is strange because the OPF tutorials work fine even with pp >2.2.0. It would be great if you could take a look. Best!
As far as I remember, case5 was never converging. This must be a different issue. In Matpower/Pypower, case5 is converging, as it is already initiliazed in the optimal state.
I am also trying to solve the acopf for case5() and it is not converging either. Do you have any idea about why this is happening? Thanks a lot!
Hello, the problem with the non-converging OPF in pandapower>=2.3.0 seems to be that the default for calculate_voltage_angles was changed from False to True (see https://pandapower.readthedocs.io/en/v2.3.0/about/changelog.html).
When you set calculate_voltage_angles=False, the OPF should work again. Why the OPF is failing when you want to compute voltage angles, I don't understand either. However, this is a quick solution to have a working OPF again.
