Wind power plants can be realized with different generator types using different control principles. The choice of the generator regardless of control method, potentially destabilizes the grid, and can even lead to grid collapse. For independent grid (. on islands) this risk is especially great. The report aimed at giving the reader a general overview of the control methods, and the developers a better understanding of each generator type to get the right choice for their wind power project. | Journal of Computer Science and Cybernetics, , (2014), 313–334 DOI: REVIEW PAPER GENERAL OVERVIEW OF CONTROL PROBLEMS IN WIND POWER PLANTS NGUYEN PHUNG QUANG Institute for Control Engineering and Automation, Hanoi University of Science and Technology; Abstract. Wind power plants can be realized with different generator types using different control principles. The choice of the generator regardless of control method, potentially destabilizes the grid, and can even lead to grid collapse. For independent grid (. on islands) this risk is especially great. The report aimed at giving the reader a general overview of the control methods, and the developers a better understanding of each generator type to get the right choice for their wind power project.

Many projects have been carried out, in parallel with both (more or less) successful and not yet successful results. The weaknesses that make exploitation of such systems more difficult are caused by insufficient understanding of the operating principles, especially the principle of control. Even the projects with (more or less) success also contain potential long-term risks to the national grid. On the one hand the paper presents an overview of .
