Abstract

Custom Power is the application of power electronics to improve the quality of power distribution for sensitive industrial plants. Industries reporting production stops due to voltage disturbances, like short interruptions and voltage dips. Power electronics converters connected in series or shunt with the grid and equipped with energy storage can provide protection against voltage disturbances. This work focuses on the voltage source converter (VSC) connected in series with the grid for mitigation of voltage dips as well as swell. The core of this work is the dual vector current controller provide the error voltage. By using the pulse width modulation (PWM) we will generate the switching pulses to the voltage source converter which provide the mitigation for sag and swell. The controller consists of two loops as name as voltage control and vector current control loop. In this work PWM is used. Controllable series compensation is used for power quality improvement under sag and swell.
