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...

Original scientific paper In this paper, the necessity of the protective relay of the micro-grid is described as the anti-islanding protection and Low Voltage Ride Through (LVRT), and the fault characteristics of the renewable energy sources are analysed. The applicability of over-current protection, distance protection, differential protection, pilot protection, voltage protection and frequenc...

The growing installed wind capacity over the last decade has led many energy regulators to define specific grid codes for generation systems connecting electricity grid. These requirements impose strict laws regarding Low Voltage Ride Though (LVRT) and High (HVRT) capabilities of turbines during voltage disturbances. main aim this paper is propose LVRT HVRT strategies that allow remain connecte...

To integrate the high penetration of power from wind farms into a grid, one key requirements posed by new grid codes is Low Voltage Ride Through (LVRT) capability. This paper studies voltage compensation-based methods to improve fault ride-through capability grid-connected Doubly Fed Induction Generator (DFIG). Bridge Type Fault Current Limiter (BTFCL) and Reactive Power Control (RPC), which ac...

Recently, the establishment of technical standards for grid connection has gained interest in academia and industry. These have focused on reactive power control function grid-connected inverter maintenance operation, include detailed information about support function. However, remote communication devices functions, other distributed sources, such as wind energy storage systems, than inverter...

The doubly fed induction generator (DFIG)-based wind energy conversion system (WECS) suffers from voltage and frequency fluctuations due to the stochastic nature of speed as well nonlinear loads. Moreover, high penetration into power grid is a challenge for its smooth operation. Hence, symmetrical faults are most intense, inflicting stator winding low voltage, disturbing low-voltage ride-throug...

Abstract Given the “carbon neutralization and carbon peak” policy, enhancing low voltage ride-through (LVRT) capability of wind farms has become a current demand to ensure safe stable operation power systems in context possible severe threat large-scale disconnection caused by farms. Currently, research on LVRT mainly focuses suppressing rotor providing reactive support, while impact active out...
