Abstract:electric power demand side management break the traditional management mode, change simply rely on expanding the supply capacity to meet the needs of power growing, dealing with the relationship between the supply side and the demand side on a higher level, emphasizes the enthusiasm of users to participate in load management, and implements power consumption management together with users. According to this characteristic, this paper analyzes the current situation of the most popular data mining technology, and has a review of power demand side management based on date mining from the power demand side management response, orderly use of electricity and energy efficiency management respectively. It is concluded that the power demand side management based on data mining is the main development direction of future power demand side management. Research on how to apply data mining technology to the user demand side management, not only promote the further development of power demand side management, but also accelerate the rapid transformation of the electric power industry, and provide technical support for the rapid construction of energy Internet.
