Ultra-short-term Probabilistic Forecasting of Wind Power Based on Temporal Mixture Density Network
Probabilistic forecasting of wind power can provide critical boundary conditions for the safe operation of new power systems. Improving forecasting accuracy is the key problem of the research for probabilistic forecasting of wind power
and improving the interpretability of implicit models is beneficial to the promotion and application of artificial intelligence models. Therefore
a temporal mixture density network is proposed
which extracts the local moment information of time series data of wind power as input channels. The temporal convolutional network is used to extract the multi-time-scale probabilistic features
and the mixed Beta distribution is used to construct the probabilistic forecasting information. The results of the case study show that the local moment channel effectively improves the convergence of the model training
and the mixed distribution parameters extracted by the temporal mixture density network have a certain interpretability. Compared with the existing models
the forecasting results of the temporal mixture density network have better accuracy.
