Conventional power management schemes for standalone wind systems typically use maximum power point tracking (MPPT) methods to extract maximum power from the wind even when the energy storage has reached its capacity. By doing so, the dummy load suffers from unnecessary stress when the load and energy storage element cannot absorb the excess power. This paper proposes an intelligent sensor-less fuzzy-logic...
This paper proposes two effective maximum power point tracking (MPPT) algorithms for two different wind energy conversion systems connected to the grid using permanent magnet synchronous generator (PMSG). The wind turbine (WT) is connected to the grid via back-to-back PWM-VSC for the first scheme, whereas, the WT is connected to the grid via diode-bridge rectifier, boost converter and the grid side...
This paper presents the control and modeling of a wind energy system that consists of a single-switch three phase boost converter with a sensorless maximum power point tracking (MPPT) method. The single-switch three phase boost converter, which has the advantage of using one switch in the converter to achieve power factor correction for the generator output current, and is able to simplify the control...
The paper studies the performance of variable speed wind turbine (VSWT) configuration with non-inverting buck-boost converter. The wind turbine systems consist of permanent magnet synchronous generator (PMSG) connected to diode rectifier, DC chopper and load. New control strategy, based on the maximum power point tracking (MPPT) and limited power point tracking (LPPT) algorithms is used to improve...
This paper presents a Model Reference Adaptive Control (MRAC) approach for a Wind Energy Conversion System (WECS) to track the maximum power point. This WECS includes a permanent magnet synchronous generator (PMSG) fed by a matrix converter. Since the mechanical power generated by the wind turbine is a function of its shaft speed at a given wind velocity, the proposed controller provides the desired...
