Switch of wind power generation

Are switched reluctance generators suitable for wind energy conversion?

Switched reluctance generators (SRGs) are suitable candidates for wind energy conversion systems, as they present a simple structure, robustness, a wide range of speed and are capable of operating in harsh environments. The machine, however, poses challenges such as high torque ripple, acoustic noise production and highly nonlinear behavior.

What is a wind energy conversion system?

Wind Energy Conversion System The wind energy conversion system (WECS) contains wind turbines and converter converters. Using wind turbines to extract the wind’s mechanical energy, the generators convert it into electrical energy, and the converter system is in charge of transferring the generated energy to the power network or a battery bank.

What is the control scheme of wind generators?

Thus, the control scheme of wind generators will play an important role in the future power system (Rocabert et al., 2012; Olivares et al., 2014; Fraile, 2021). Currently, the grid-following (GFL) control scheme with the phase-locked loop (PLL) has been widely used in the wind power generation system.

Which technology will dominate the future generation of wind turbines?

The increasing of power level in wind turbines is driving the technology of power electronics toward medium voltage operation. The medium voltage power converters will dominate the future generation of wind turbines due to their cost-effective, compact, and reliable design.

How can we improve wind energy conversion?

This principle of enhancing wind energy conversion should be met by ensuring the safety and integration of WECS technologies such as generators, power electronics converters, and grids. According to research reports [32, 33], WECS technologies have promisingly improved recently, and this has enabled to maximize wind power generation at fewer costs.

How do wind generators control the frequency of a power system?

As the wind energy penetration increases, the power system’s (grid) frequency gets affected. Wind generators participate in the control of frequency control through advancements in technology. Verma and Kumar developed a load frequency control strategy for a two area interconnected power system based on DFIG.
