Technological Advancement in PMSG Based Wind Energy Conversion Systems: Issues and Challenges

Abstract

Background: Since its beginning in 1980, wind energy generation has gained newer heights and emerged as the most promising renewable energy technology at present. Wind turbine rating has increased from few kW to MW and now multi-MW turbines are also available and in operation too. Introduction: Impact of wind turbines on the grid has significantly increased with increased penetration of wind power into the grid. In order to improve the performance characteristics of the wind turbines, and make them suitable for grid integration, more advanced generators, control schemes, and power converters are required. Latest wind energy market trends and research articles reflect the popularity and market capture of Permanent Magnet Synchronous Generator (PMSG) for wind turbine applications. Method: The present work is dedicated to important electrical aspects concerning PMSG based wind energy conversion system. Starting with the technological development of wind turbine, state-of-the-art PMS based wind turbine concepts with power electronic converter topologies are discussed. Result: A comprehensive analysis of converter topology, grid integration, integration issues, and future research and technology trends are presented.In addition steady state performance analysis of PMSG based wind turbine is presented depicting issues with different control schemes. Conclusion: The study presented in this paper envisages help to the researcher in this area by providing them clear insight of various power electronic interfaces, their control complexities and various issues of concern. In addition we are assure that steady state analysis presented in this paper will attract the newcomers in this field of research.
