Power grid short-term load analysis and prediction method

Abstract

The invention discloses a power grid short-term load analysis and prediction method. Line short-term load prediction is carried out mainly through manual intervention and comprehensively considering the practical state of each load line of a power grid, and short-term load prediction curves of each transformer substation, each user administration department and each region of the power grid are obtained in a formula calculation accumulation way. The power grid short-term load analysis and prediction method achieves the quick analysis of the accuracy of the load prediction curves by comparing the prediction curves with the practical curves, quickly finds out the reason of load change, takes an effective solution timely to lower the influence, solves the problem that the traditional load prediction system does not have sub-line and sub-station prediction, and improves the prediction accuracy of power grid short-term load prediction.

Description

Technical field [0001] The invention relates to a method for short-term load analysis and load forecasting of a power grid. Background technique [0002] At present, the short-term load analysis and forecasting methods of the power grid are mainly based on the historical data of the total load of the power grid, with reference to recent user load fluctuations, weather changes and other factors to carry out load forecasting. This load analysis and forecasting method is mainly based on the total grid load, and its accuracy is relatively low. Especially during the spring and autumn power grid equipment maintenance period, the impact of the grid equipment maintenance on the grid load cannot be fully considered, and the prediction error is large. Summary of the invention [0003] In order to solve the long-term difficulty in analyzing and predicting short-term load of the power grid by means of substation and branching, the present invention provides a method for analyzing and predicti...
