New Classes of Volterra Integral Equations of the First Kind Related to the Modeling of the Wind Turbine Dynamics

... integral equations of the first kind are defined. They appear when the duration of the rise front is taken into account in test signals. The test signals are chosen considering specific features of the inputs arising in practice as applied to dynamics of wind turbines with horizontal rotation axis. The inversion formulas for indicated classes of one-and two-dimensional Volterra integral equations of the first kind are obtained. © 2020 IEEE. нет

Advanced adaptive frequency support scheme for DFIG under cyber uncertainty

... support of wind farms in a cyber uncertainty environment, and proposes an advanced adaptive frequency support scheme for doubly-fed induction generator (DFIG). In the proposed scheme, both the minimum rotor speed and the deloaded operating level of wind turbines are required to be determined at first. Then, an advanced adaptive droop control method is proposed with consideration of cyber uncertainty to improve the response speed of wind turbines for frequency support. Finally, the stability of the ...

Use of gasifier-based electric power stations for improving the economy of autonomous power supply systems in Russia

... waste of logging and woodworking that can be used for energy production are generated. In this paper, we consider an autonomous power supply system, including a wood biomass gasification power plant (BGPP), a diesel power plant (DPP), one or several wind turbines (WT), and electricity consumers with their load schedule. The mathematical formulation of the problem of optimizing the structure and modes of operation of the power supply system is reduced to minimizing the objective function with a number ...
