In this paper, the authors propose an on-line neural network based Distributed STAtic COMpensator (DSTATCOM) for a three-phase, three-wire grid connected distribution system to mitigate the voltage flicker. The technique is based on instantaneous tracking of the voltage envelope and phase angle using online neural network based estimator. These estimated values are used by neural controllers to compute inputs to Hysteresis Current Controller (HCC), which generate switching signals for DSTATCOM. Online estimation and control makes the system faster, more adaptive and more robust to the changes in system parameters and disturbances.
