Embodiment Construction
[0055] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0056] An ultra-short-term prediction method for photovoltaic power generation based on self-learning composite data sources, including inputting data to obtain autoregressive moving average model parameters;
[0057] Input the input data required for photovoltaic power generation prediction into the autoregressive moving average model determined according to the parameters of the autoregressive moving average model to obtain the prediction result;
[0058] Perform post-evaluation on the forecast results, that is, analyze the error between the predicted value and the measured value. If the forecast error is greater than the maximum allowable error, then re-establish ...
