New intelligent direct power control of DFIG-based wind conversion system by using machine learning under variations of all operating and compensation modes

Energy Reports, 2021
Wind Turbine (WT)-based Doubly-Fed Induction Generator (DFIG) is a nonlinear system, in which the wind has variable behavior, and the local reactive power depends on the random demand of the AC grid; all these make conventional controls insufficient for ...

Synergetic-PI controller based on genetic algorithm for DPC-PWM strategy of a multi-rotor wind power system

Scientific Reports, 2023
This work designs a powerful new nonlinear control technique using synergetic control (SC), proportional-integral (PI) controller, and genetic algorithm (GA) for multi-rotor wind energy (MRWE) conversion systems, whereby an asynchronous generator (AG) is

Towards a domain-specific approach to the study of parental psychological control: distinguishing between dependency-oriented and achievement-oriented psychological control [PDF]

, 2010
Theory and research suggest that psychologically controlling parenting can be driven by parental concerns in two different domains, that is, interpersonal closeness and achievement. Three studies addressing this hypothesis are presented. Study 1 provides

New application of artificial neural network-based direct power control for permanent magnet synchronous generator

Electrical engineering & Electromechanics, 2021
Purpose. This article proposes a new strategy for Direct Power Control (DPC) based on the use of Artificial Neural Networks (ANN-DPC). The proposed ANN-DPC scheme is based on the replacement of PI and hysteresis regulators by neural regulators ...

Vascular remodeling of the mouse yolk sac requires hemodynamic force [PDF]

, 2007
The embryonic heart and vessels are dynamic and form and remodel while functional. Much has been learned about the genetic mechanisms underlying the development of the cardiovascular system, but we are just beginning to understand how changes in heart ...

Remote power control strategy based on virtual flux approach for the grid tied power converters [PDF]

, 2018
The control of active and reactive power for the Renewable Energy Sources (RES) based power plants are very important. The injection of active and reactive power to the grid is normally controlled at the Point of Common Connection (PCC) where this point ...

Improved control strategy of DFIG-based wind turbines using direct torque and direct power control techniques [PDF]

, 2018
This paper presents different control strategies for a variable-speed wind energy conversion system (WECS), based on a doubly fed induction generator. Direct Torque Control (DTC) with Space-Vector Modulation is used on the rotor side converter.
