High energy consuming companies have abundant adjustable resources. The study of the electricity generation and consumption behavior of typical industrial consumers under time-of-use tariffs will guide the development of price-based demand response strategies. Firstly, the production constraints of different power generation facilities are studied, and the production relation-ship, timing relationship and regulation characteristics of different loads are analyzed to establish the model of power generation cost,load transfer cost and net electricity cost of industrial users, to form the economic optimization model of power generation and consumption of typical industrial users. Secondly, according to the production characteristics of three kinds of typical industrial users,the economic optimization model of power generation and consumption is established. Finally, the effectiveness of the method is demonstrated by arithmetic examples. The regulation strategies of electricity generation for different industrial users during price changes are studied and their regulation potential is compared and analyzed.
