Embodiment Construction

[0030] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] see figure 1 As shown, a space load forecasting method in a power system includes:

[0032] Step 1: Pre-set the prediction indicators such as land use type, building land area and simultaneous rate of power planning in each region, and store them in the partition database. The partition database provides basic data management functions for space load forecasting, and the partition database also provides load density parameters. and a comparative database of required coefficients.

[0033] Specifically: First, according to the detailed planning of land use types provided by the planning departments of various prefectures and cities in a certain province, the prefec...

Abstract

The invention relates to a space load predicting method in an electricity system. The space load predicting method comprises the following steps: setting the electricity planning prediction indexes of each region, wherein the electricity planning prediction indexes comprise electricity planning land use types, building land area and a simultaneity factor; storing the electricity planning prediction indexes of each region in a partitioned database; predicting space load in the electricity system according to the electricity planning prediction indexes of each region, stored in the partitioned database. Through the adoption of the method, the prediciton result of the space load in the electricity system can be obtained.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a space load forecasting method in the power system. Background technique [0002] Power load forecasting refers to the analysis and research of the historical load data of the power system, and the use of qualitative and quantitative methods such as statistics, mathematics, computer, engineering technology and experience analysis to explore the internal relationship between things and the law of development and change. Preliminary estimates and projections are made for the development of loads. The accuracy of power load forecasting results is directly related to the benefits of power investment, the reliability of power supply, the normal development of power demand, and the economic and social benefits of society. However, it is very difficult to achieve accurate or relatively accurate forecasting, because there are quite a lot of factors affecting power load forecasting, and bec...
