Load Characteristics Analysis And Forecasting Research Of Hebei South System

Associating with the situation of electric power market in Hebei south system, primo analysis the general situation of load and power supply in Hebei south system, research load curve of system, major industry, residents, agricultural, analysis alteration of power consummation and indicate alter tendency of load characteristics, and through research indicate the relation between annual average daily load factor, min daily load factor and power consummation structure is strictly linear regression relation. Then use some methods to indicate load of Hebei south system, examined with actual power consummation indicate the modified gray model based on equal dimension and new information has the most accuracy. In the end regimentation the 2008 summer-winter typical daily load curve based on 2006 load curve using method of synthesis typical daily load curve superposition.
