Comprehensive Review on Fault Ride-Through Requirements of Renewable Hybrid Microgrids

The world is interested in applying grid codes to increase the reliability of power systems through a micro-grid (MG). In common practice, MG comprises wind farm, and/or photovoltaic (PV) arrays that are integrated with diesel generators and energy storage devices. Fault ride-through (FRT) capability an important requirement codes. FRT means still connected during numerous disturbances such as faults. This required ensure there no loss generated due Reactive currents must be injected into system stability restore voltage. To enhance for doubly fed induction generator (DFIG) based WT installation, internal control modifications rotor-side converters grid-side applied. solutions depend on these traditional advanced techniques. Advanced techniques needed non-linear nature less robustness ones. External hardware devices also added improve DFIG which classified protection devices, reactive injection A comprehensive review enhancements DFIG-based WTs, PV systems, MGs using software methods presented this effort. classification characterized plus various inverter indicated.
