Adequate compensation of DSTATCOM-based FGS for mitigating the impact of source disturbances in radial power systems

Electrical power systems are often exposed to disturbances due to various factors (internal and external). One of these disturbances is source voltage disturbance. The source voltage sags and swells, significantly affecting sensitive loads and the rest of the system's equipment, causing them to work less well or even break down. Because of this, the effects of these disturbances on the power system should be lessened. One of the most effective solutions is to employ modern power electronics technologies such as Distribution Static Synchronous Compensator (D-STATCOM) as one of the custom power devices. Conventional PI controllers are commonly used in D-STATCOM but are not adaptive to large disturbances, which can lead to significant performance degradation. Also, the tuning methods of their parameters are tedious and time consumed. In this work, a fuzzy gain scheduled (FGS) controller integrated with PI parameters was used to provide adaptive performance in a wide range of source voltage disturbances for a radial power system. The optimal parameters were found by the response optimizer tool. Simulation of the system operation was carried out using MATLAB/Simulink software. The simulation results showed adaptive performance and superiority in response speed and overshoot value in the fuzzy control unit compared to the traditional PI units.
