Challenges of large wind generation intermittence and fluctuation for future smart grids

With introduction of smart grid concept, how to face up to the impacts of grid-connected renewable energy sources, especially like wind power on power systems becomes one of the most important issues in development of smart grid. This paper will discuss the potential challenges the smart grids will confront with respect to large wind generation intermittence and fluctuation from a technical point of view. The context will involve power system planning, reliability evaluation, voltage stability and frequency stability. Technical requirements and solutions in dealing with those challenges imposed by wind generation for future smart grids are also proposed.
