D-STATCOM is an important component to compensate for the required reactive power in the distribution lines. Generally, a cascaded PI control structure is used to control a D-STATCOM. However, the performance of this conventional PI-based loop control deteriorates under the output filter and severe load variations. To mitigate the negative effects of such variations on the D-STATCOM performance, this paper proposes a novel approach not need the accurate model of the system. This new method exploits an adaptive controller in the current loop and a conventional PI controller in the voltage loop. The simulation and hardware experimental results indicate this new controller provides low total harmonic distortion (THD), robustness against parameter and load variations, and fast transient response.
Keywords: D-STATCOM, Adaptive Lyapunov control, parameter variations, compensation, cascade loop control
