Analysis of integrated wind power cost based on Dynamic Economic Dispatch

As smart grid developing in China, renewable energy gains more and more attention, and a few large farms of power plant are building. Considering wind power´s instability and fluctuation, large-scale integration of it has considerable impact on the electric network and generates a series of additional costs. In this paper, we characterize the stochastic wind power via probability distribution function (pdf) and cumulative distribution function (cdf), analyze the integrated cost of wind power in the context of Dynamic Economic Dispatch (DED). Numerical examples are provided for a test system. We also give suggestions to wind power´s price setting in china.
