Abstract: This paper deals with the automatic generation control (AGC) of three area interconnected thermal power systems with combination of the automatic voltage control using automatic voltage regulator (AVR). The interconnected thermal unit is considered with three area concept. The primary object of the AGC is to balance the total system generation against system load and losses, so that the desired frequency and power interchange with neighboring systems are maintained in order to minimize the transient deviations and to provide zero steady state error in appropriate short time. Further the role of automatic voltage regulator is to maintain the terminal voltage of synchronous generator in order to maintain the bus bar voltage. Otherwise bus bar voltage goes beyond permitted limit. The interaction between active and reactive power demand is also analyzed in this paper. In this paper Load scheduling strategy is also considered in combination with AGC and AVR, in which utility takes steps to control the peak demand of plant by shifting peak load of different consumers towards valley with the aim of system stability, minimize the generation cost, postpone/ delay construction of new plant. Literature survey also shows, almost no attempt is made to combine the AGC with load scheduling strategy.
