Power Prediction Model of Photovoltaic Plants Based on Improved GM Model

摘要

In order to improve the prediction accuracy of GM (1, 1) model of photovoltaic (PV) plants, IAFSA is proposed and used to optimize the background values and initial values directly, and an improved GM (1, 1) prediction model is constructed in combination with the rolling data updating mode. The example of PV plants in service shows that the above-mentioned model is effective and complete, and can improve the prediction accuracy of the GM (1, 1) model.
