A Novel Method to Improve Power Quality in Electric Vehicle Charging Station Integrated Distribution System

The growing adoption of electric vehicles (EVs) has introduced notable challenges in maintaining power quality within electrical grids, primarily due to the fluctuating charging demands. These fluctuations can lead to issues such as voltage instability, harmonic distortions on distribution networks. This paper proposes the development of a Distribution Static Synchronous Compensator (D-STATCOM) using a voltage source converter with a DC link, designed to inject reactive power and voltage into the distribution line to address power quality concerns related to EV charging. As a dynamic reactive power compensator, the D-STATCOM helps to stabilize voltage, reduce harmonic distortions, and enhance the overall power factor in distribution systems. This paper demonstrates the implementation of D-STATCOM utilizing a Sinusoidal Pulse Width Modulation (SPWM) control technique is carried out in MATLAB/Simulink.
