Abstract: The peak value load of main electric power consumer such as steel works causes to waste electric power re- source, in short supply of mains power and to increase electric cost for consumer. The project of electric load demand side management (DSM)for Xigang Steel make the electric load(demand)to decrease by about 10%-5022 kW by using “tend analysis” principle and by means of adjusting and controlling the main equipment - electric arc furnace. It is a available way for electric load control (DSM)of main electric power consumer, economizing electric expense and alleviating the pressure of supplying power in city.
