Power consumption growth rate calculation method and device

Abstract

The invention discloses a power consumption growth rate calculation method. The method comprises the steps of obtaining a target air temperature data sequence of a month to be evaluated and a corresponding historical air temperature data sequence; carrying out piecewise linear fitting on the target air temperature data sequence to obtain an optimal fitting function, calculating the air temperatureload sensitivity of the optimal fitting function in each preset temperature interval, and then calculating the daily air temperature influence quantity sequence of the month to be assessed; calculating the total air temperature influence electric quantity of the month to be evaluated according to the daily air temperature influence quantity sequence and the influence hours; and performing calculating to obtain the actual power utilization growth rate of the month to be evaluated by removing the influence of the total air temperature on the actual power consumption. The invention further discloses a corresponding electric quantity growth rate calculation device. By implementing the embodiment of the invention, the influence of the weather temperature on the calculation accuracy of the power consumption growth rate can be effectively avoided, the calculation accuracy of the power consumption growth rate is improved, and the power consumption service quality of a power system is improved.

Description

technical field [0001] The invention relates to the field of electricity consumption analysis in electric power systems, in particular to a method and device for calculating the growth rate of electricity consumption. Background technique [0002] Nowadays, the development of all walks of life is inseparable from the support of electricity. The calculation of the power consumption growth rate of the power system has a significant impact on many aspects such as power system planning, power system operation and power market. The calculation of the power growth rate can better predict the power demand, improve the power service quality and power management efficiency of the power system, and ensure the safe and reliable operation of the power system. In the prior art, the electricity consumption growth rate is usually calculated by counting the electricity consumption in the same period of each year. [0003] However, during the process of implementing the present invention, t...

Problems solved by technology

[0003] However, in the process of implementing the present invention, the inventors have found that the prior art has at least the following problems: In addition to being affected by economic development and its own cyclical laws of the industry, the demand for electricity is also affected by other external factors

For example, high-power consumption equipment for residents is cooling, heating and other equipment. The use of these equipment is closely related to meteorological factors such as temperature. The method of calculating the growth rate of electricity consumption based on the amount of electricity obviously cannot reflect the actual growth rate of electricity consumption well, which in turn affects the reasonable prediction and scheduling of electricity demand by the power system
