摘要: 对于存在多个影响因素的中长期电力负荷,采用常规灰色模型GM(1,1)进行中长期预测不能获得较好的预测精度。提取了中长期负荷主要影响因素之一的生产总值和年总用电量建立了多变量灰色预测模型MGM(1,2)。为进行比较分析,同时还建立了常规灰色GM(1,1)模型。预测结果显示,多变量灰色模型MGM(1,2)的预测精度优于常规灰色模型GM(1,1)。

Abstract: For the mid-long term power load that are affected by multiple factors, the general grey model GM(1, 1) can’t provide satisfactory accuracy for the mid-long term forecasting. Therefore, the multivariable grey forecasting model MGM(1, n) is proposed by using the data of total electric power consumption and total output value of Chongqing region. Besides, the general grey forecasting model GM(1, 1) is also established to compare and analyze the prediction accuracy. The forecasting result shows that the proposed model MGM(1, 2) in this paper is superior to the general grey forecasting model GM(1, 1) in forecasting accuracy.

Key words: mid-long term power load, grey system, MGM(1, m), influencing factor, load characteristics
