摘要：
Battery energy storage system is an ideal choice to stabilize the prediction error of wind power. Under the premise of current price of energy storage battery, the optimal configuration of power and capacity of battery energy storage system becomes especially important. Based on the power prediction error distribution characteristics of wind farm and in accordance to the constraint conditions and assessment indicators in the standard of wind power prediction and forecasting, the characteristic relations between the power of battery energy storage system and the wind power prediction error, the reduction rate of wind power forecasting error, the root-mean-square error, accuracy rate and qualified rate of all-day prediction results as well as the characteristic relations between the capacity of energy storage system and the contentment rate of capacity requirement, the growth rate of capacity requirement satisfaction are analyzed. To stabilize wind power prediction error better and make the input cost lower, based on cut-off normal distribution method a method to optimize the power and the capacity configuration of energy storage system is proposed, and the proposed method can be applied to calculate the power and capacity of a better energy storage system for tracking the planned output of wind farm. The validity and feasibility of the proposed method are verified by actual case calculation and analysis.
