Static Synchronous Compensating Voltage Control in Power System Using Flat Adaptive Control

Static Synchronous Compensator (STATCOM) is a FACTS device whose structure is based on a voltage source converter and is installed in parallel to control the voltage of the transmission line in the power system. In this paper, a flat adaptive control system for STATCOM output voltage control is simulated. By linearizing the nonlinear dynamics and changing the system state variables, the controller designs the rules of control input stability, and an adaptive rule is obtained for designing the controller coefficients with the least system error. In the simulation results, the adaptive controller is compared with the traditional PI controller.
