Aiming at the problems of declining power prediction performance and high appraisal cost of photovoltaic (PV) power plants year by year
this paper proposes an optimization method integrating bidirectional long short-term memory network (Bi-LSTM) and attention mechanism. First
the time dependence of power data is captured by applying Bi-LSTM to improve the understanding of time series changes; second
the combined attention mechanism enables the model to focus on the features that have the greatest impact on the prediction results to further improve the prediction accuracy; and finally
the accuracy is verified by using field historical data modeling. The field model deployment shows that the model can better capture the rapid power changes compared with the traditional single model and integrated learning model
and the ultra-short-term prediction accuracy of the field station can be improved by more than 10%.
