System imbalance due to power fluctuation is the first concern of power grid with large scale wind power integration. Traditional studies are limited in time domain, where the modeling is not convenient enough. In this paper, a model based on frequency domain is proposed. This model is more precise, and capable to take some important factors, such as the layout of wind farm, into account. This paper also presents a fast engineering implementation of this model, which can be applied on different power system studies. The case studies show this model can perfectly evaluate the ramp rate and reserve requirement of power systems, no matter under normal or extreme weather condition, therefore the validity and flexibility of this model get proved.
