摘要:

家庭用电量多年来一直在不断增长。为了应对这种增长,有必要对家庭的消费情况进行智能管理,以便家庭可以节省电费,并可以减少高峰时段对电网的压力。然而,实现这样的方法是具有挑战性的,由于存在随机性的电价和消费的电器。为了应对这一挑战,我们采用了一种无模型的方法,该方法适用于有关不确定因素的有限信息的家庭。更具体地说,家庭和电网之间的相互作用可以被建模为一个非合作的随机对策,其中的电价被视为一个随机变量。为了寻找博弈的纳什均衡(NE),我们采用了一种基于分布式深度强化学习的方法。此外,所提出的方法可以保护家庭的隐私。然后,我们利用Pecan Street Inc.的真实数据,其包含超过1000个家庭的电力消耗概况,以评估所提出的方法的性能。平均而言,结果表明,我们可以实现约12%的峰均比(PAR)和11%的负载方差减少。通过这种方法,可以降低电网的运行成本和家庭的用电成本。

英文摘要:

The power consumption of households has been constantly growing over the years. To cope with this growth, intelligent management of the consumption profile of the households is necessary, such that the households can save the electricity bills, and the stress to the power grid during peak hours can be reduced. However, implementing such a method is challenging due to the existence of randomness in the electricity price and the consumption of the appliances. To address this challenge, we employ a model-free method for the households which works with limited information about the uncertain factors. More specifically, the interactions between households and the power grid can be modeled as a non-cooperative stochastic game, where the electricity price is viewed as a stochastic variable. To search for the Nash equilibrium (NE) of the game, we adopt a method based on distributed deep reinforcement learning. Also, the proposed method can preserve the privacy of the households. We then utilize real-world data from Pecan Street Inc., which contains the power consumption profile of more than 1; 000 households, to evaluate the performance of the proposed method. In average, the results reveal that we can achieve around 12% reduction on peak-to-average ratio (PAR) and 11% reduction on load variance. With this approach, the operation cost of the power grid and the electricity cost of the households can be reduced.
