Intraday Power Trading for Imbalance Markets: An Adaptive Risk-Averse Strategy using Mixture Models
<|reference_start|>Intraday Power Trading for Imbalance Markets: An Adaptive Risk-Averse Strategy using Mixture Models: Efficient markets are characterised by profit-driven participants continuously refining their positions towards the latest insights. Margins for profit generation are generally small, shaping a difficult landscape for automated trading strategies. This paper introduces a novel, fully-automated cross-border intraday (XBID) trading strategy tailored for single-price imbalance energy markets. This strategy relies on a strategically devised mixture model to predict future system imbalance prices, which, upon benchmarking against several state-of-the-art models, outperforms its counterparts across every metric. However, these models were fit to a finite amount of training data typically causing them to perform worse on unseen data when compared to their training set. To address this issue, a coherent risk measure is added to the cost function to take additional uncertainties in the prediction model into account. This paper introduces a methodology to select the tuning parameter of this risk measure adaptively by continuously quantifying the model accuracy on a window of recently observed data. The performance of this strategy is validated with a simulation on the Belgian energy market using real-time market data. The adaptive tuning approach enables the strategy to achieve higher absolute profits with a reduced number of trades.<|reference_end|>
