Comparative Review of Wind Turbine Generators and Power Electronic Converters for Grid Integration

Abstract: Coal-fired power plants (PPs) are one of the biggest causes of today's catastrophic climate crisis. To deal with this problem, there is a need to completely decarbonize the energy segment using zero-emission renewable energy sources (RES). Wind turbine (WT) farms are one of the fastest-growing energy solutions globally. These massive complexes consist of huge WT that harness wind energy, convert it into electricity, and send it to the utility grid (UG) for use alongside traditional energy sources. Integration of WT energy into the UG is interesting and could be a valuable solution for dealing with future energy challenges. Given the challenges faced regarding the connection between large WT farms and the UG using induction and synchronous generators (I&SGs), it is necessary to study and compare varying WT generator systems. This research analyzes and compares the connections of varying WT generators and their control using varying power electronics converters (PECs). This paper also discusses the current status of generators and PEC in WT concepts. He showed that a double-fed induction generator (DFIG) driving a variable-speed WT is more efficient compared to other generators.
