Design of Grid Current Compensator for Grid-Connected Distributed Generation under Nonlinear Loads

Abstract

This paper deals with the current control method for grid related operations of distributed generations below non-linear loads using dq-srf technique. The proposed approach has contemporary controller which is designed in DQ-synchronous reference body (dq-srf) and composed of PI controller. More over the proposed technique does now not need any sensors for dimension harmonic evaluation of grid voltage and in addition to harmonics are eliminated to the maximum extent. Hence this may be effortlessly followed at any disbursed era which adds as an advantage. The operation precept of proposed current controller is validated thru MATLAB SIMULINK.
