[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0036] A smart grid load forecasting method, such as figure 1 shown, including the following steps:
[0037] Step 1. Collect electricity load data of the park for 12 months a year and observe its trend.
[0038] In this step, the figure 2 It can be seen that there is no obvious trend in the change of electricity consumption over time, so the simple regression analysis method cannot be used to predict the electricity load, and the Newton interpolation method is a better choice.
[0039] The 12-month electricity consumption data of the park is shown in Table 1.
[0040] Table 1 24-hour electricity load data in the park (kWh)
[0041]
[0042]
[0043] Step 2. Select appropriate training data for training and prediction of the Newton interpolation model.
[0044] In this step, in order to perform error estimation and correction, three sets of data ar...
