Wind power control strategy based on high precision prediction technology

Abstract

This paper proposes an active power control strategy for wind farms based on high-precision prediction technology. The aim of this study is to improve the absorptive capacity of large-scale wind farms, reduce network loss and promote the operation economy of wind farms. The strategy divides the active power dispatching into four layers. Based on the constraints of the safe operation of the power grid, the corresponding objective function and power allocation method for each layerare given. The result of this study shows that the strategy proposed can effectively improve the operation economy of the power grid and promote wind power consumption. Compared with the traditional control strategy, the proposed control strategy can well deal with the actual situation of large power fluctuation, and reduce the number of wind turbine start-up and shutdown.
