For doubly-fed induction generator (DFIG)-based wind turbines (WTs), various advanced control schemes have been proposed to achieve the low voltage ride through (LVRT) capability, whose parameters design is significantly reliant on rotor electromotive force (EMF) of DFIG-based WTs. However, influence current EMF usually ignored in existing studies, which cannot fully reflect transient character...

Overvoltage and overcurrent resulting from various faults cause instability in Doubly Fed Induction Generator (DFIG)-based wind turbines connected to a grid. The grid code requirement must be met during minimize the effect of these problems. Low Voltage Ride Through (LVRT) capability is used meet requirement. It important use coordinate control for transient states LVRT capability. This study a...

The integration of wind generation to the grid is growing rapidly across world. As a result, operators have introduced so-called codes (GC), which nowadays include range technical conditions and requirements, generators must fulfill. Among these, low-voltage ride through (LVRT) requirement for turbines stay connected continue operate during disturbance. In this study, control structure, combini...

Brushless doubly-fed induction generators have higher reliability, making them an attractive choice for not only offshore applications but also remote locations. These machines are composed of two back-to-back voltage source converters: the grid side converter and rotor converter. The is typically used reactive current control power winding using current. A low ride through (LVRT) fault detecte...

As large-scale wind turbines are connected to the grid, modeling studies of farms essential power system dynamic research. Due large number in farm, detailed each turbine leads high model complexity and low simulation efficiency. An equivalent method for farm is needed reduce complexity. For with widely used doubly-fed induction generators (DFIGs), existing mainly focus on such continuous contr...

According to the coordination control of a dynamic voltage restorer (DVR) and an inductive fault current limiter (FCL), this paper proposes efficient low-voltage ride-through (LVRT) scheme for doubly fed induction generator (DFIG) based wind turbine.

In recent years, grid-connected photovoltaic (PV) power generations have become the most extensively used energy resource among other types of renewable energies. Increasing integration PV sources into network and their dynamic performances under fault conditions is an important issue for grid code requirements. this paper, a source as unified interphase controller (UIPC) to enhance low voltage...

In today’s world, the DG should not be disconnected in event of a power outage but instead remain linked to grid and supported by reactive power. This can accomplished implementing low voltage ride through (LVRT) with proportional integral (PI) controller. As result, profile enhanced. The PI controller, on other hand, has drawbacks that setting gain takes long time results an overshoot current ...

With the increasing penetration level of wind turbine generators (WTGs) integrated into power system, WTGs are enforced to aid network and fulfill low voltage ride through (LVRT) requirements during faults.
