ANN Application of the APF Improved for DG Unit System Reliability

Abstract

Generally, Power Quality is the chiefworry in the present power system. It mainly effects due to sudden changes in load, other environmental conditions. Power Quality main effects on system voltage and current. To compensate the problems in system voltage a series active filter is proposed and also for mitigating system currents a active shunt filter is implemented. The gate signals required for series and shunt filters is designed with help of system parameters and dc-link voltage of filter. To get better quality and harmonic distortion, an artificial neural network is executed to control the dclink voltage of both filters. This system is verified using Matlab/Simulink and evaluated the results with conventional controller.
