Abstract:  In order to further improve the peak-shaving ability of the terminal and promote the wind power consumption, a technology for improving the peak-shaving capacity and optimizing the wind power consumption considering the difference of the terminal “storage heat” is proposed. Firstly, according to the users electric load, heat load, heating temperature and other data, the difference of terminal heat load is analyzed. Secondly, the difference of terminal “heat storage” is analyzed on the basis of variables such as disturbance unit price, disturbance duration and heating temperature. Finally, using the scene analysis, this paper constructs different terminal thermal load spatial distribution scenarios and performs simulation calculation based on the proposed technology. The main results are as follows: 1) The wind power consumption of the near-end heat load is increased by 7.23%; 2) Load fluctuation of different types of users are within the range of their respective acceptance, the maximum fluctuation of users of class A is 6 °C, and the temperature of c users of class C is 30 °C. 3) The increase of wind power consumption and thermal power plant revenue show the technical and economic feasibility of the proposed strategy.
