Controlling of DSTATCOM for Pulsed Load by using ANN

In power system, power quality problems mainly arise due to the pulsed loads, which cause the degradation of the entire system performance during very short period of time which cause the degradation of the entire system performance. This paper presents the application of DSTATCOM to reduce the impact of pulsed load on a bus voltage and thus keep it at desired level improve the power quality in a power system during and after pulsed loads Distribution Static Compensator (DSTATCOM) is a Voltage-source Inverter (VSI) based shunt compensation device which is generally used to solve power quality problems in distribution systems. The control strategy of the DSTATCOM plays an important role in maintaining the voltage at the point of common coupling, A novel adaptive control for the DSTATCOM based on artificial Neural Network (ANN) for pulsed load is proposed in this paper. To evaluate the performance of the DSTATCOM and the ANN adaptive controller, a power system is developed in the MATLAB/SIMULINK environment. The effectiveness of the DSTATCOM and the ANN controller is examined for pulsed loads of different magnitudes and durations.
