Unwanted error in the OPF AC when trying to combine controllable out of service and non controllable in service

[Crueda96]

As mentioned in issue#926 , an unwanted error is also generated in the OPF AC when trying to combine controllable out of service and non controllable in service

Minimal Example:

import pandapower as pp
net = pp.create_empty_network()
bus = pp.create_bus(net, vn_kv=110., name="Bus 2")
pp.create_ext_grid(net, bus=bus, vm_pu=1.00, name="Grid Connection")
pp.create_gen(net, bus=bus, p_mw=5, min_p_mw = 5, max_p_mw = 20, name='gen 1')
pp.create_gen(net, bus=bus, p_mw=5, min_p_mw = 5, max_p_mw = 20, name='gen 3')

net.gen[['in_service', 'controllable']] = [[False, True],
                                           [True, False]]

pp.runopp(net,verbose = True)

Output:

---------------------------------------------------------------------------

Hi @Crueda96 ,

thank you for the minimal example, we will have a look.

Hi, I agree that this is an unwanted behaviour. I won't have the time to fix this myself, but a pull request on this would highly be appreciated!

This is related to #926 where the same bug is reported.
