This paper describes the neural controller as analogous to PI controller for voltage regulation, performance of the DVR under different voltage disturbances. PI controller is difficult to tune for non linear systems; neural will be best choice for non linear systems. Dynamic Voltage Restorer (DVR) is series controller which has capability to mitigate the voltage disturbance by injecting missing voltage in series to the load. DVR comprises of inverter, DC energy storage and series transformer.

Back-propagation concept is used for tuning an Artificial Neural Network controller as analogous to the PID controller to optimize the voltage regulation and load current disturbance. The performance of the neural based DVR is analyzed through different case studies. The circuit is simulated in matlab/simulink and results are presented to validate the proposed controller.
