Response behaviors of power generation and consumption in energy intensive enterprise under time-of-use price

An energy intensive enterprise (EIE) usually is a large electrical energy consumer with a definite flexible demand, and many EIEs have built their own industrial power plants. In consideration of the response behaviors of power generation and consumption of an EIE under time-of-use (TOU) price implemented by the utility, the effect of power prices on behaviors of power generation scheduling and load scheduling is discussed. Then, an integrated power generation and load scheduling model for daily operations of an EIE is presented. In the case study, the response behaviors of an EIE is demonstrated, and the price signal that can promote the EIE being studied to shift loads to valley hours and generate more power during peak hours is also discussed. When designing and implementing price-based demand response programs, the utility can take the unit cost of self generation and unit cost of load shifting of an EIE into account, thereby obtaining win-win solutions for both EIE and utility.
