At present the northern region vigorously promotes the coal-to-electricity project and has made rapid progress. In order to solve the problems of power grid safety, operation, operation and maintenance brought about by the coal-to-electricity process, master the heating effects and the law of electricity consumption of residents, the research and application of intelligent services for coal-to-electricity based on the ubiquitous power Internet of things (IoT) technology is proposed in this paper. It collects and communicates through the IoT technology, and realizes 5-minute high-frequency collection of heating data and energy consumption data of users of different heating types. By constructing a coal-to-electricity intelligent service platform for intelligent monitoring of user information, heating effects, and power consumption information, and the big data technology is used for data analysis, which provides reliable guarantee for grid operation and maintenance and user satisfaction, as well as provides strong support for financial subsidies in government sectors.
