This paper presents two different methods for remote generator control in power flow calculation. The first consists in extending the PQV nodes and P node types in the currently available Newton-Raphson and PQ methods by adding the voltage of the controlling generator to the relative equations， and the reactive power of the generator can be obtained. The second is， based on the traditional power flow method， to modify the reactive power of the remote generator step by step in terms of negative feedback to maintain the bus voltage of the controlled bus. The results of actual examples show that the two methods proposed are feasible and the former can effectively restrain the oscillation during iteration.
