Voltage Flickering Reduction Using Distribution STATCOM

Abstract

<em><span>Power Quality is becoming intensity concerned from both electric utilities and customers. Voltage Flicker is a major power quality problem as it has a significant impact on both the equipment and production environment. This work describes the voltage control technique of reduction of voltage flicker and clearing fault using Distribution Static Synchronous Compensator (DSTATCOM). The test system used is IEEE 9-bus distribution system clarified the optimal location of DSTATCOM by using Artificial Neural Network. A simulation was done using MATLAB/Simulink software.</span></em>

Mitigating power quality disturbances in smart grid using FACTS

“…On the other hand, if the AC bus voltage becomes lower than the VSC voltage, then STATCOM works as a capacitance connected to the AC bus and injects an amount of reactive power as desired. If the AC bus and the VSC voltages have the same value, the selected reactive power exchange is zero [23].…”
