The
integration of wind farms with the grid is of paramount importance in the quest
for harnessing renewable energy sources. This study delves into the grid
integration of a wind farm comprising six Wind Turbine Generators (WTGs) and
places a specific emphasis on load flow analysis to assess voltage profiles
across various buses, as well as Active and Reactive Power flow
characteristics. Furthermore, the research investigates the intricacies of
short circuit analysis, encompassing both three-phase and single-line-to-ground
fault scenarios at various bus locations. Relay coordination schemes are
explored to optimize fault isolation strategies within the system. One of the
prominent challenges addressed in this study is the integration of wind farms
at voltage levels such as 33 kV or 66 kV, often situated at locations remote
from the grid's central infrastructure, where the grid's strength is relatively
weaker. This scenario can pose a significant threat to power system protection
since inverter-based generators have lower inertia, potentially affecting their
ability to provide fault currents detectable by conventional protection
systems. The paper concludes by discussing the encountered challenges and
proposing areas for future research and innovation. The comprehensive model
used in this study is developed within the ETAP environment.
