Abstract:With the gradual increase in the utilization rate of heating equipment such as air conditioners and electric heating in winter, the impact of temperature on Hubei power grid load has become increasingly obvious, and hit a record high under the influence of extremely cold weather on January 24, 2024. In order to understand the influence of air temperature on the load of Hubei power grid, the change curve of maximum load and air temperature during the winter peak in Hubei Province in the past four years was firstly sorted out. By selecting the current situation of electricity consumption in typical working days and rest days of each industry, the load characteristics and change rules of each industry in Hubei Province were analyzed. Secondly, combined with the electricity consumption of Hubei online power grid, the changes of basic electricity and heating electricity of each industry over the years are analyzed, and the changing trend of electricity consumption and temperature is revealed. Finally, based on the historical data, the correlation and sensitivity of heating load, electricity and air temperature are analyzed, and the maximum load difference and temperature difference of temperature drop are calculated, and then the development law of heating load, electricity and air temperature is studied and analyzed, which provides a theoretical basis for the power department to scientifically formulate the winter kurtosis scheduling plan.
