Method and system for evaluating new energy power prediction error

The invention discloses a method and system for evaluating a new energy power prediction error, and the method comprises the steps: obtaining new energy power prediction, calculating a deviation value of the new energy power prediction, and carrying out the normalization processing of the deviation value; on the basis of the normalized deviation value of the new energy power prediction, abnormal data identification is carried out on historical actual data of the new energy power prediction, the identified abnormal data are replaced, and new energy historical actual power after replacement is obtained; and evaluating a new energy power prediction error based on the new energy power prediction and the new energy historical actual power. According to the new energy power prediction evaluation method and system provided by the invention, by constructing the evaluation method and system provided by the invention, an error link of new energy power prediction can be accurately evaluated, and an important basis is pr
