IEEE 13 case power flow

[rhythm232]

Hi
How to use pandapower to perform power flow calculation on IEEE 13 case?

define unsymmetric line as standard type (component library)

line_601 = {"r_ohm_per_km": 0.4060, "x_ohm_per_km": 0.3895, "c_nf_per_km": 0.012029, "r0_ohm_per_km": 0.4060,"x0_ohm_per_km": 1.2036,"c0_nf_per_km": 0.0054415,"max_i_ka": 0.5}
pp.create_std_type(My_13case,line_601, name="line_601",element = "line")

create lines

line_r650_632 = pp.create_line(My_13case,from_bus=b650, to_bus=b632, length_km=0.6096, name="Line_r650_632",std_type="line_601",type="ol",index="r650632")

create trafos

t1 = pp.create_transformer(My_13case, hv_bus=b633, lv_bus=b634, std_type="unsymmetric_trafo", name="Trafo")

create network feeder

r650 = pp.create_ext_grid(My_13case, bus=b650, vm_pu=1.05, p_mw=0.8, min_p_mw=0.05, max_p_mw=0.8,
q_mw=0.5, min_q_mw=0, max_q_mw=0.5,name="Grid Connection", s_sc_max_mva=1000, rx_max=1, x0x_max=1, r0x0_max=1)

but it seems doesn t work

could someone help me?
Thank you

Hi, @rhythm232. As I mentioned in #836, the less-than-3-phase line hasn't been implemented in pandapower. Maybe one of the maintainers can confirm again.

You can use OpenDSS for unbalanced ACPF with less-than-3-phase lines.

Hi Edward Xu Thank you for your reply. I used Opendss for unbalanced ACPF. However it seems cant use for OPF. Do you know any method could get the result of 3-phase OPF like IEEE 13? rhythm232 At 2023-04-30 21:29:36, "Edward Xu" ***@***.***> wrote: Hi, @rhythm232.

You're welcome. You can see if https://github.com/lanl-ansi/PowerModelsDistribution.jl works for you.

It's also possible to model unbalanced networks with a positive-sequence (O)PF tool, by modeling each phase explicitly and handling the per unit conversion correctly.

it is correct, at the moment it is not supported in pandapower.
