Difference between grid connections of large-scale wind power and conventional synchronous generation
regions with abundant wind energy resources are generally located at the end of power grids. The power grid architecture in these regions is typically not sufficiently strong
and the energy structure is relatively simple. Thus
connecting large-capacity wind power units complicates the peak load regulation and stable operation of the power grids in these regions. Most wind turbines use power electronic converter technology
which affects the safety and stability of the power grid differently compared with conventional synchronous generators. Furthermore
fluctuations in wind power cause fluctuations in the output of wind farms
making it difficult to create and implement suitable power generation plans for wind farms. The generation technology and grid connection scheme for wind power and conventional thermal power generation differ considerably. Moreover
the active and reactive power control abilities of wind turbines are weaker than those of thermal power units
necessitating additional equipment to control wind turbines. Hence
to address the aforementioned issues with large-scale wind power generation
this study analyzes the differences between the grid connection and collection strategies for wind power bases and thermal power plants. Based on this analysis
the differences in the power control modes of wind power and thermal power are further investigated. Finally
the stability of different control modes is analyzed through simulation. The findings can be beneficial for the planning and development of large-scale wind power generation farms.
