摘要
电力负荷系统是典型的灰色系统,电力负荷特性指标的预测具有直接的经济意义.讨论了当预测对象系统存在转折性变化时,灰色预测校正模型在此方面的有效应用.该模型具有充分利用历史信息而且短期预测精度高的优点.
Electric load system is a typical grey system and the forecast for the inder of electric load characteristics has a directly economical meaning.The application of the grey forecast adjustment-model to electric load is discussed when the system has the turning point. The new model has a advantage of being able to utilize the history information and to make the high precision short-term load forcasting.
