Cover Story: This paper introduces a new metric that emphasizes the accurate forecasting of extreme prices, enabling better model selection for storage profit maximization. Maximizing storage profit relies on the purchase of energy at low prices and their subsequent sale at high prices. This requires accurate predictions of the price peak hours and the determination of the optimal times to buy or sell stored energy. While price prediction is crucial, conventional metrics like mean squared error (MSE) are inadequate for selecting prediction models, as the MSE equally weights all price prediction errors and fails to prioritize the high and low prices. The results show that the proposed metric outperforms the standard ones, leading to more precise profit estimation for storage and other trading activities. View this paper
