To Maintain Voltage Regulation A STATCOM Provides The Fast And Efficient Reactive Power. In order to
understand various STATCOM control methods are discussed in the literature. But in those methods they use the trial
and error approach methods so the performance is trade off. so at different operating points the control parameters
may not be effective for the optimal performance. In order to overcome this problem an adaptive control technique came
in to picture, in which the control gains automatically self adjusted as per our desired response even with the
change of operating condition that’s why we named as autonomous adjustment. In the simulation test, the adaptive PI
control shows consistent excellence under various operating conditions, such as different initial control gains,
different load levels, change of transmission network, consecutive disturbances, and a severe disturbance. when there is
a change of system conditions the conventional STATCOM control with tuned, fixed PI gains usually perform fine in
the original system, but may not perform as efficient as the proposed control method.
