Novel STATCOM controller for reactive power compensation in distribution networks with dispersed renewable wind energy

This paper presents a novel multi-loop dynamic error driven controller based on the decoupled (d-q) voltage and current tracking loops for modulating the Static Synchronous Compensator (STATCOM) used in distribution networks with dispersed renewable wind energy generation. The multi loop regulator adjusts the pulse switching pattern of the Voltage-Sourced Converter (VSC) to ensure effective reactive power compensation and harmonic reduction. The effectiveness of the controller is fully validated under different operating conditions, like load switching and wind velocity excursions.
