Abstract
Renewable energy resources have become more widely integrated into the electricity system in recent years. Wind plays an essential role in the energy mix since it is a renewable, clean, and abundant source of electricity. Increased wind power penetration in the electrical system, on the other hand, might have a negative impact on electricity quality and create new operational issues. This study examines topics such as maximum power point tracking, fault ride-through capabilities, inter-area and sub-synchronous oscillations, and voltage flicker as they pertain to the integration of wind farms into the power system, as well as existing control systems. This document also outlines upcoming obstacles and possibilities. This paper presents the classification of wind turbine, its control techniques and review of literature about the earlier work done in the field of transient stability using FACTS controller.
