Comparative Analysis between DVR and D - STATCOM for DFIG Based WECS Integrated to Grid

Abstract

The instabilities in the power supply, such as voltage spikes, transients, and distorted waves, can cause consumer electronics to malfunction or even fail altogether. It is one of the biggest worries for gridconnected WECS in the present and future.In a variety of ways, specialized power electrical devices can improve power quality. These days, power applications make use of a broad variety of flexible controllers that take use of advanced power electronic components.In order to effectively minimize various forms of power quality concerns in a grid-connected wind energy conversion system, this article evaluates the reliability of two distinctive electrical devices, the Distribution Static Compensator (DSTATCOM) and the Dynamic Voltage Restorer (DVR). MATLAB/SIMULINK is used to examine the devices’ performance.
