This paper evaluates the performance of several control methods for small-scale variable speed wind turbines (WTs) in wind energy systems (WES). The methods that will be studied are maximum power point tracking (MPPT) control for below rated wind speed operation and yaw and stall control for above rated wind speed operation. In the paper, the simulation platform used for the study is described, yaw...
Hybrid stand-alone power systems offer an achievable arrangement in remote and island zones where grid connection is not monetarily or in fact suitable. Nonetheless, the intermittent way of renewable energy sources and mismatch between the generated power and load demand are the principle challenge. In this way energy storage device is required to ensure efficient, reliable and secure power supply...
The doubly fed induction generator (DFIG) is most exploited for wind power generation, It provides the benefits of variable speed operation by improved power quality, increased energy capture, and reduced mechanical stress on the wind turbine, The proposed algorithm presented in this paper is applied to a Doubly Fed Induction Generator (DFIG) with a stator directly connected to the grid and a rotor...
This paper deals with design and control of a connected wind energy generation system employing a Permanent Magnet Synchronous Generator (PMSG) driven by a variable speed wind turbine feeding single-phase loads. The proposed energy conversion system makes use of asymmetric NPC five level inverter. The dc terminal of the generator connected rectifier is tied to a boost converter for Maximum Power Point...
