Abstract

The invention relates to a space load prediction method and belongs to the field of power systems. The method includes the steps of firstly, predicting the land using information of a planning year, and dividing lands of the planning year according to communities to determine the classification load density index of a future year; secondly, calculating the load saturation value of each community in the future year, and calculating the total classification load amount and total load saturation value of the future year at the same time; thirdly, using the data of the second step to predict the load distribution of an old city area; fourthly, using the data of the second step to predict the load distribution of a new city area through space deduction; fifthly, checking the load prediction result of the planning year; sixth, continuing checking if the checking result is unsatisfactory until the checking result is satisfactory. By the method, the problem that the prediction load of all same-classification old city areas is obtained according to unified classification load average density is solved, prediction precision is improved effectively, and additional data can be obtained easily.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a space load forecasting method. Background technique [0002] With the continuous development of modern industry and agriculture and the improvement of people's living standards, the society's demand for power supply is increasing. In order to meet the rapidly developing power demand, the power industry management department, one of the important sectors of the national economy, must continuously expand the scale of the power system. Therefore, it is also facing an increasingly heavy task of power grid development planning. [0003] Urban load forecasting has the following characteristics: (1) urban load is scattered in various load areas, and the proportion of point load is not large; (2) historical load data and load saturation value can be used to predict the development trend of future load, and can Use the urban master plan or urban land use plan as a reference from which to e...
