The global demand for electrical energy is growing at twice the rate of primary energy demand. The current power system scenario necessitates very stable and high-quality power. Wind turbines and solar photovoltaic systems are examples of distributed generation that are important in the perception of green energy. To reduce CO2 emissions, electricity generation from renewable sources such as wind and solar is preferable. Wind energy is one of the most rapidly evolving energy streams among the sustainable options. The percentage of renewable energy in global generation is steadily increasing. The evolution of various wind energy conversion systems (WECSs) is discussed in this chapter, along with their benefits and drawbacks. The growing use of power electronic converter (PEC)-based renewable energy is changing power system dynamics and raising new issues about stability. Several concerns in the power system with the incorporation of wind energy are also covered, including power quality difficulties, low voltage ride-through (LVRT) capability, fault ride-through (FRT) capability, power oscillations, primary frequency regulation (PFR), virtual inertia support, and so on. Low voltage ride-through capability indicates that the WECS must remain connected to the grid (as per grid code) and produce a certain amount of reactive power during grid disturbances (with voltage dip). Grid code requirements in various nations will be met by the DFIG-based WECS, which will provide grid assistance during voltage dips produced by various grid breakdowns. To accomplish fault ride-through capability, the rotor side converter (RSC) and grid side converter (GSC) can be correctly controlled according to the grid code requirements.
