Complex signal mismatch (simulink error)

Hi dears
when i am trying run my simulink file appear this error
Complex signal mismatch. Input port 1 of 'IEEE_9bus_new_o/Wind Farm 60 MW/Wind Farm/Csa' expects a signal of numeric type real. However, it is driven by a signal of numeric type complex
Component:Simulink | Category:Model error
Complex signal mismatch. Output port 1 of 'IEEE_9bus_new_o/Wind Farm 60 MW/Wind Farm/From1' is a signal of numeric type complex. However, it is driving a signal of numeric type real
If someone can help me I'll be thankful to him.

Is the block labeled Csa a Controlled Current Source? https://www.mathworks.com/help/physmod/simscape/ref/controlledcurrentsource.html

In the subsystem Wind Farm, the gain block labeled a^2 turns out to be programmed as exp(-j*2*pi/3) which uses j = sqrt(-1) so the gain is complex not linear and not squared. The output lb is complex. That does not appear to be permitted for use as an input to a Controlled Current Source.

You should also be looking into the cause of,
