Problems solved by technology

Electricity cannot be directly stored like coal, oil and other resources, and its production, transportation and consumption can only be carried out at the same time. Too much supply will cause huge waste of resources, while insufficient supply will seriously affect people's daily life and bring economic losses.
In addition, the huge investment makes the construction of the power grid have a certain time lag

Abstract

The invention discloses a modeling method of a power use load prediction system for a power client. The method comprises a step of grouping the power use loads of the historical days of several past years into a working day group and a non-working-day group, a step of modeling the power use loads of the working day group and a non-working day group according to the grouping result, a step of matching prediction days with the grouping result according to working days and non-working days so as to matching the model of a corresponding set to predict the prediction day load to obtain a preliminary prediction result, a step of obtaining a prediction day error correction value by using a Markov calculation prediction error transfer matrix, and a step of obtaining a final prediction result by the preliminary prediction result and the prediction day error correction value. According to the method, the prediction of the power use load is realized, a basis is provided for the investment planning of a power grid, and the working efficiency of the power grid is improved.

Description

technical field [0001] The invention relates to the field of electricity consumption forecasting, and more specifically, relates to a modeling method for an electricity consumption load forecasting system of an electric power client. Background technique [0002] Accurate forecasting of power consumption is the basis of power system operation and planning, and the basis for power companies to formulate distribution plans and business strategies. As a special commodity, the production, transmission, distribution and use of electric energy have distinct characteristics compared with other industrial products. Electricity cannot be directly stored like coal, oil and other resources, and its production, transportation and consumption can only be carried out at the same time. Too much supply will cause huge waste of resources, while insufficient supply will seriously affect people's daily life and bring economic losses. In addition, the huge investment makes the construction of ...
