[0037] The present invention will be further described below in conjunction with the drawings and embodiments.
[0038] Please refer to figure 1 , The present invention provides a method for short-term power prediction of photovoltaic power plants based on cyclic neural network, including the following steps:
[0039] Step S1: Obtain corresponding NWP meteorological parameters according to the weather type of the day to be predicted;
[0040] Step S2: Collect historical data historical power and historical NWP meteorological parameters several days before the day to be predicted;
[0041] Step S3: Process historical power and historical NWP meteorological parameters, and use the processed historical data as a training data set;
[0042] Step S4: Use the cyclic neural network to learn the training data set, and use the stochastic gradient descent method to adjust the parameters of the network to obtain a prediction model;
[0043] Step S5: Use the NWP meteorological parameters of the day ...
