A New Power Prediction Accuracy Evaluation Method of Renewable Energy Plant

In the modern power system with a high rate of renewable enery, the high-precision new energy power prediction is of great significance to ensure the safe and stable operation of the power grid. Aims at the shortcomings of the commonly used power prediction accuracy methods, a new accuracy evaluation method is proposed, which can accurately reflect the deviation degree of power prediction data. Based on the actual data of a wind farm, the proposed method is compared with the common evaluation methods, according to the results of the comparison, the effectiveness of the proposed method has been verified.
