Impacts of Wind Power Uncertainties on Power Grid and Corresponding Countermeasures

This paper, first of all, discusses the probability model of wind power, time series model and prediction error model for needs of different studies. Secondly, based on the present studies, the impacts of the wind power uncertainties on the reliability of the power generation system, the planning of the power system and the short-time dispatching and control of the system are explored. The research shows that these impacts are mainly negative. Finally, possibilities and feasibilities of utilization of energy storage system to attenuate the uncertain performance of the wind power generation is described briefly as well.
