Influence of Wind Power Generation Integrating into Power Grids

One important aspect of constructing smart grids is to solve the problem of integrating renewable energy generation,such as wind power generation,into power grids.Wind power generation has the trend of being integrated to power grids as the form of large-scale wind farms,which influences on power grids.This paper discusses in general terms the problems which are encountered by the developers of wind power generation projects and by power grids when dealing with projects to integrate wind farms to power grids.The influence includes balance of generation and consumption,frequency and active power control,voltage and reactive power control,reserve management,power flow,stability,power quality,secondary system due to the characteristics of dynamic and stochastic performance of wind power generation.Since the power grids were not designed specifically to accommodate this type of generation,there are inevitably some points at which modifications must be executed if existing standards of electricity supply are to be maintained.It is important to analyze the influence and relating countermeasures for utilizing the wind power more efficiently.
