Abstract: The proportion of electric heating load in winter power grid load is increasing day by day, and its distribution characteristics have important reference value for power service, power grid dispatching and power grid planning, and is one of the most important bases for power grid construction. In this paper, the load data of electric heating station area are mined and analyzed, and the influence factors of electric heating station area energy use are analyzed and discussed. XGBoost based method is used to analyze the energy use of the "coal to electricity" station area, and the weight of different factors on the load rate of the electric heating station area is obtained based on the characteristics of the main influencing factors. At the same time, the distribution rules of maximum load ratio and probability density are analyzed. In addition, the influence of different influencing factors on the distribution load of "coal to electricity" is analyzed, and the characteristics and specific scope of the three types of application areas of "electric heating high, medium and bottom" are delimited and relevant suggestions are put forward.
