Messages for api QVENGINE4 Invalid study bus 20002 [5ROB275A275.00]: (003286) Its voltage is controlled by generation at bus 20333 [5ROB_SC115.000] (003306)

Does anybody know what 'invalid bus study' means here? And why, when I follow the same sequence/approach for another case with exactly the same buses but with just a different dispatch, it runs smoothly without any trouble! Your help is greatly appreciated.

As the error message says: The generation at bus 20333 is controlling the voltage at bus 20002. Hence, it is not possible to perform QV-analyses at a controlled bus.

Either remove bus 20002 from the list of buses of interest or remove the remote control of plant at bus 20333.
