Abstract

This paper discusses the dynamic voltage restorer (DVR) supported wind power generator connected to the grid to improve the low voltage ride through (LVRT) capability of the grid. The wind power generators are connected to the grid through a feeder to the distribution system and the DVR is connected to the point of common coupling (PCC), where loads are connected. The main aim of the DVR is to regulate the voltage at the load terminal irrespective of sag/swell, distortion, or unbalance in the grid voltage. The proposed DVR structure is operated in such a fashion that it does not supply or absorb any active power during the steady-state operation. Dead beat control algorithm is used for the control of DVR. The DVR supported wind power system operation is verified through extensive simulation study and a prototype experimental setup is built for experimental verification.
