Power Quality Improvement in Distribution Network using DSTATCOM

The development of power electronic devices in modern applications has caused a decline in power quality in distribution networks due to an increase in nonlinear loads on the consumer side. Problems include harmonic currents, imbalanced loads, inadequate voltage regulation, and high reactive power demand are symptoms of this deterioration. The distortion of the supply current caused by harmonic currents makes them a major concern. To address this problem, this paper utilizes a Distribution Static Synchronous Compensator (DSTATCOM) setup employing Sinusoidal Pulse Width Modulation (SPWM) and a Synchronous Reference Frame (SRF) extraction approach. MATLAB/Simulink is employed to model and simulate the DSTATCOM system. The PWM generator is calibrated using the DQ theory as a fundamental principle to power the DSTATCOM. A thorough evaluation of the DSTATCOM’s performance enhancements is carried out by a comprehensive analysis of total harmonic distortion (THD). This method improves power quality and reduces harmonic currents in the distribution network.
