In the case of asymmetric fault, the modern new power grid requires that the doubly-fed
induction generator (DFIG) still has good low voltage ride-through (LVRT) capabilities. To …

The impact of environmental degradation and the energy crisis, countries are vigorously
developing renewable power generation technology. Among renewable energy sources …

Under normal working conditions, the stator flux of doubly-fed induction generators only
includes the forced component; thus, controllers are mainly designed in accordance to this …

In this paper, a nonlinear control scheme based on backstepping theory for dynamic voltage
restorer (DVR) is proposed to mitigate the voltage disturbances for loads under grid voltage …

In this paper, a nonlinear control scheme for dynamic voltage restorer (DVR) is proposed to
reduce the voltage disturbances for loads under grid voltage sags and nonlinear loads. First …
