Abstract
This paper deals with the mathematical modelling of the steady-state effects of the automatic secondary voltage control (voltage control by means of co-ordinated injected reactive power from remote generation buses). In this paper, an extended load flow model is proposed, in which these effects are encompassed by application of the automatic adjustment approach. To include the effects of remote voltage control correctly in the load flow calculation, the generalization of the standard PV type bus is done by introducing new types of buses. The practical importance of this mathematical model lies in its easy utilization in professional software packages for steady-state security assessment. The proposed methodology was verified on a test example of the Yugoslav high voltage power system.
