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.

I. INTRODUCTION

With the progress of society, the importance of energy, especially electric energy, has become more significant in 21st Century China. However, the development of electric industry has been seriously restricted by the shortage of primary energy and the expansion of traditional power plants may also increases CO2 emission that consequently causes serious environment problems. Under this situation, the exploitation of wind energy which provides new solutions to the contradiction between economic development and environment pollution has been inevitable.
