The practical value of wind power generation system

Wind power generation is power generation that converts wind energy into electric energy. The wind generating set absorbs wind energy with a specially designed blade and converts wind energy to mechanical energy, which further drives the generator rotating and realizes conversion of wind energy to electric energy.

Wind power generation is one of the most mature and promising power generation methods for large-scale commercial development. Wind power generation has the advantages of being clean and pollution-free, low power generation cost, less actual land occupation and simple operation.

The wind farms which accesses to power grid cause fluctuations and reactive power redistribution and sometimes lead to voltage collapse. Similarly, the dynamic voltage stability is a major challenge faced by distribution network operators.

In the context of the ever-increasing close connections between energy and water systems, the quantification of water conservation volume by wind power systems is becoming another key consideration in power technology selection (Zhang et al., 2018). Despite all these merits, wind power brings significant downsides as well.

Fig. 5 is the typical framework of a wind power generation system. For a wind power generation system, the wind turbine is a critical part. Modern wind turbines (Fig. 6) can be divided into horizontal axis wind turbines (HAWT) and vertical axis wind turbines (VAWT).

These requirements are twofold: first, wind generation systems must operate effectively under diverse grid conditions and disturbances arising from interactions between wind generation systems and the grid; and second, wind generation systems are mandated to provide various auxiliary services to ensure the optimal operation of the power systems.
