Electric power system load forecasting using separated modeling of Gompertz model

Based on further investigating the separated modeling method of grey system, we have studied general grouping number of GM (1, 1) separated modeling and mergence method of data. It is obtained that the mergence function is commonly the special situation of the S-step average function. Combining the thought of related degree, the separated modeling method of Gompertz model is put forward. Taking the forecast of the power consumption some network as an example, the calculation results indicate that the error is smaller than 1%.
