The Analysis and Evaluation of Two Ways for Multi-step Wind Power Prediction

Wind power prediction is significance for the operation of wind power grid integration.The study of wind power prediction mainly forcus on the prediction method,but Wind power prediction is awalys multi-step prediction,lacking analysis of the way for multi-step prediction.This paper take analysis on rolling and multi-sampling scale multi-step wind power prediction.The precision of the way of multi-step wind power prediction relate to the prediction method and the wind power data.The precision level between the two ways is different with different prediction method or wind power data.Take ultra-short term wind power forecast as example,the evaluation of two ways for multi-step wind power prediction is based on the evaluating indicator of national energy administration about wind power prediction,using the real data from a wind farm of Jilin Province.
