越来越多的零售能源市场显示出价格波动，为用户提供了以低于平均价格购买能源的机会。我们建议将这种廉价的能源暂时储存在电池中，并在能源价格高时使用它来满足需求，从而使用户能够利用价格变化，而不必将需求转移到低价格时期。我们研究了产生最佳性能的电池控制策略，即，最大限度地降低总成本。最优策略具有一个阈值结构，我们在一些特殊情况下推导出这些阈值。通过大量的数值实验证明了从能量存储中获得的成本节约，并为未来的研究提供了各种方向。
An increasing number of retail energy markets show price fluctuations, providing users with the opportunity to buy energy at lower than average prices. We propose to temporarily store this inexpensive energy in a battery, and use it to satisfy demand when energy prices are high, thus allowing users to exploit the price variations without having to shift their demand to the low-price periods. We study the battery control policy that yields the best performance, i.e., minimizes the total discounted costs. The optimal policy is shown to have a threshold structure, and we derive these thresholds in a few special cases. The cost savings obtained from energy storage are demonstrated through extensive numerical experiments, and we offer various directions for future research.
