摘要:
It has been well recognized that modeling spikes (i.e., jumps) are an essential task in asset pricing, risk management and trading activity. Due to the complexity and uncertainties in the power grid, spot electricity prices are highly volatile and normally carry with spikes, which may be tens or even hundreds of times higher than the normal price. Another issue comes from modeling the intra-day seasonality and its evolution over time. The first part of our proposed scheme considers the hourly spot prices within one day as a high dimensional vector and applies the non-decimated wavelet analysis to detect the spikes for training. The second part utilizes the gradient boosting trees for the spikes prediction with carefully selected predictors from Australian electricity markets. Extensive numerical experiments show that our approach improves the prediction accuracy.
