Problems solved by technology

However, in the process of distribution network planning, the capacity of lines, transformers, and distribution stations cannot use the existing load forecast results, and more rely on the artificial estimation of planners, which greatly reduces the accuracy of distribution network planning. sex

Embodiment Construction

[0050] based on the following figure 1 Preferred embodiments of the present invention will be described in detail.

[0051] The invention provides a bottom-up refined load forecasting method to assist enterprises in decision-making in various aspects. In order to achieve the above purpose, two aspects need to be considered, one is to analyze the historical load data, and the other is to consider the impact of various types of user industry characteristics on the demand coefficient. Based on the whole and focus on the part, the method is more scientific and reasonable.

[0052] Such as figure 1 As shown, the present invention provides a load forecasting method based on installed capacity, comprising the following steps:

[0053] Step S1, using the relationship between the demand coefficient and the macro characteristic data of various types of user industries to establish a mathematical model of the demand coefficient;

[0054] Step S2, respectively input the historical loa...

Abstract

The invention provides a load forecasting method based on installed capacity. The method is characterized by, carrying out regression analysis calculation on historical load data of a user and macroscopic property data in each type of user industry to obtain coefficient of a regression equation; carrying out grey prediction on the macroscopic property data in each type of user industry; substituting the coefficient of the regression equation and the user macroscopic property data obtained after grey prediction to a mathematical model of demand factors, can carrying out calculation to obtain demand factors; and carrying out point, line and plane load prediction by utilizing the demand factors and the installed capacity data of each user. On the basis of the installed capacity of the user, the method enables the load to be hierarchical, so that accurate point, line and plane load prediction is achieved; and the method can accurately guide implementation of distribution network planning, can greatly improve equipment utilization rate, reasonably controls equipment load rate and improves power supply reliability.

Description

technical field [0001] The invention relates to a load forecasting method based on installed capacity. Background technique [0002] Load forecasting is the basic work of distribution network planning, construction, transformation, and operation, and it is the basic information that power grid operation departments and planning and development departments must have. The rapid development of the economy and the continuous advancement of electric power informatization have put forward higher requirements for the accuracy of load forecasting. Accurate load forecasting plays a guiding role in power generation, transmission, and distribution. The accuracy of load forecasting will affect the scientificity of distribution network planning. At present, the reform of my country's electric power system is underway. The focus of the new power reform plan is "four liberalizations, one independence, and one strengthening", that is, the liberalization of operational electricity prices ot...
