高耗能企业通常是所在地区的用电大户，具备一定量可调度负荷，许多高耗能企业还建设有自备电厂。针对分时电价下高耗能企业发用电响应问题，讨论了各时段之间的价格关系对高耗能企业发用电响应行为的影响，进而建立了高耗能企业自发电调度和负荷转移一体化调度模型。针对案例企业情况，讨论了不同价格信号下企业的发用电决策，并讨论了能够促使企业将用电向谷时转移并在峰时多发电的电价信号。研究表明，电网在制定基于价格的需求响应机制时如果充分考虑企业的自发电成本、负荷转移成本等信息，电网可以通过价格手段引导高耗能企业的发用电决策，从而实现电网和企业的双赢。

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.
