基于电池的储能技术已经成为各种电网能源优化的使能技术,例如调峰和成本套利。电池驱动的调峰优化的一个关键组成部分是峰值预测,它预测一天中需求最大的时间。虽然在负荷预测方面已经有大量的前期工作,但我们认为,预测个体消费者或微电网的需求高峰时期的问题比预测电网规模的负荷更具挑战性。我们提出了一个基于深度学习的高峰预测新模型,该模型可以预测每天需求最高和最低的k个小时。我们使用156座建筑物的真实微电网的两年跟踪来评估我们的方法,并表明它比适用于峰值预测的最先进的负荷预测技术高出11% -32%。当用于基于电池的调峰时,我们的模型为这种微电网每年节省496,320美元的4兆瓦时电池。
Battery-based energy storage has emerged as an enabling technology for a variety of grid energy optimizations, such as peak shaving and cost arbitrage. A key component of battery-driven peak shaving optimizations is peak forecasting, which predicts the hours of the day that see the greatest demand. While there has been significant prior work on load forecasting, we argue that the problem of predicting periods where the demand peaks for individual consumers or micro-grids is more challenging than forecasting load at a grid scale. We propose a new model for peak forecasting, based on deep learning, that predicts the k hours of each day with the highest and lowest demand. We evaluate our approach using a two year trace from a real micro-grid of 156 buildings and show that it outperforms the state of the art load forecasting techniques adapted for peak predictions by 11--32%. When used for battery-based peak shaving, our model yields annual savings of $496,320 for a 4 MWhr battery for this micro-grid.
