Application of Advance Control Logic for Power System Automatic Generation Control

Abstract

The steady state analysis of voltage stability is vital thing for study of power system stability. The voltage collapse is occurred due to different reason of power system. The main reason is frequency unbalance, and changing of reactive power in transmission line due to change of load. If voltage and frequency is fluctuating a long period whole power system may be collapse. This creates ice landing of grid failure and black out of a major area. So the analysis of this problem is very much essential how to overcome from this problem. The reactive power is changing due to change of excitation, and frequency is changing due to changing of load demand. None of them can be tolerated to the power system. So here research about this small topic how to control the load frequency, when the load is continuously changing and maintain the power system voltage stability. This approach has been analyzed in different ways with using different software by different authors. Here we have analyzed the problem by using MATLAB simulink.
