can you elaborate?
I tried creating the shunt element with positive and negative q_mvar and the results of the power flow calculation are different.
import pandapower as pp
import pandapower.networks as nw
net = nw.example_simple()
s_id = pp.create_shunt(net, 4, q_mvar=10)
pp.runpp(net)
net.res_bus.loc[[4]]
vm_pu va_degree p_mw q_mvar
4 1.019452 1.800451 0.0 10.392832
net.shunt.at[s_id, 'q_mvar'] = -10
pp.runpp(net)
net.res_bus.loc[[4]]
vm_pu va_degree p_mw q_mvar
4 1.029751 1.77725 0.0 -10.603874
It looks like the function _pandapower.createshunt() creates only a shunt capacitor, not a reactor. I tried changing the sign of the value of the q_mvar parameter, but it fails to model the component as a shunt reactor.
