Load Forecasting Method Based on Gray Related Weighted Combination with Revised Parameter

For the Gray model GM(1,1) is not fit long-middle term load forecasting as well as imprecision caused by overlarge broken vertical bar a vertical bar, the paper proposes a novel method of forecasting long-middle term power load: Weighted forecasting method of gray related degree with revised parameter. The method can make various factors weakened or counteracted and prevent the forecasting data from increasing too fast. The effectiveness of the proposed model is demonstrated by a test in a certain area. The result shows that the method is useful both in theory and in practice.
