In power system, voltage stability is considered as performance measurement parameter. Hence to achieve voltage stability, Static Compensator (STATCOM) is used. In last few years, STATCOM has been used to enhance the performance of the power system. It can regulate a system’s voltage by providing fast and efficient power support. However, previously there are many different STATCOM control systems that have been studied which includes fundamental Proportional Integral (PI) controller. The experimentation approach to obtain the PI gains or studies with trade off of relevance and execution. Hence, the performance at an operating point for some control parameters may vary for same control parameter at different operating point. To improve performance of control system at different operating conditions, this study proposes the control model which can self-adjust the control gains such that always give desired response during disturbances. The simulations results of the adaptive PI control for different operating conditions such as transmission network, load level, control gain, severe and consecutive disturbances shows excellent consistence. The conventional STATCOM perform well for same operating condition, but when it comes for system condition change proposed control method shows upper hand over previous conventional method.
