A review on the integration of wind farms with variable speed wind turbine systems into power systems

With the development of wind energy and power electric control technology, more wind farms with variable speed wind turbine systems (VSWTS) are integrated into power grids. While VSWTSs improve the stability and power quality of systems, several new problems are introduced in power grid. This paper provides an overview to the relevant latest research issues related to the integration of wind farms with VSWTSs.
