Static Compensators (STATCOMs) with voltage control are known for their fast reaction time to stabilize the grid voltage. For optimal dynamic performance it is essential to adjust the gain settings for the voltage controller, for different states of operation. This paper presents a new gain adaption algorithm to passively adapt to changes in the grid stiffness as well as to other dynamic voltage controlling devices, in order to provide stable STATCOM behavior in all system conditions. The proposed control will not need communication between the FACTS units. Which consequently simplifies and enhances the control systems even under severe grid changes.
