[0004]
However, the current prediction level of new energy power generation output cannot meet the needs of the actual operation of the power system; in order to improve the prediction accuracy of new energy power generation power, the factors that affect the new energy power generation power prediction can be analyzed by evaluating the new energy generation power prediction error, and Adjust the forecast of new energy power generation power according to the influencing factors, so as to improve the accuracy of new energy power generation power forecast
[0005] Existing new energy power generation prediction error evaluation technologies are usually based on the prediction results and actual results for the macroscopic overall results, and cannot quantify and analyze the errors caused by each key link in the new energy power generation power prediction, and cannot carry out corresponding optimization in a targeted manner measures, not conducive to improving the power prediction accuracy
