This paper presents a simulation of an onshore energy conversion system connected to the electric grid and under a strategy of a supervisor control based on deterministic version of a finite state machine. The simulation is planned to address an analysis on performance due to the action of the supervisor. The supervisor is included at the higher level, having the objective of analyzing the operational...
This paper presents a control strategy based on two distinct controllers for different operating regions applied to a wind turbine benchmark. In previous works, we proposed the control of a wind turbine using two distinct controllers for all operating regions. The contribution of this work focus on the use of two distinct controllers for two different operation regions, the fuzzy proportional integral...
This paper deals with a wind turbine control simulation supported by the use of computational tools appropriate to simulate complex systems. High performance and reliability are required for wind turbines to be competitive within the energy market. A key challenge for control systems is the wind power which is an uncontrolled input and also acts as a disturbance. A discrete adaptive LQG (linear quadratic)...
This paper is on variable-speed wind turbines with permanent magnet generator. A three-mass drive train model and two different topologies for the power-electronic converters are considered. The two different topologies considered are respectively a matrix and a multilevel converter. A control strategy, based on fractional-order controllers, is proposed for the wind turbines. Previous papers were...
This paper is concerned with the behavior of a variable-speed wind energy conversion system, in order to assess the power quality injected in the electrical grid. Different topologies for the power-electronic converters are considered, namely two-level and multilevel converters. We use pulse width modulation by space vector modulation associated with sliding mode for controlling the converters, and...
