摘要:

公用事业公司引入了需求电荷以鼓励客户减少其需求峰值,因为高峰值可能给公用事业公司和消费者带来极高的成本。我们在此研究配备了储能设备和自产可再生能源的客户的账单最小化问题。我们精心设计了一种无模型强化学习算法,以同时降低消费者的能源费用和需求电荷。所提出的算法不需要能源需求和可再生能源产量的预测模型。生成的控制器可在线使用,并随着新收集的数据逐步改进。该算法在IFPEN Solaize site一栋办公楼的真实数据上进行了验证。数值结果表明,我们的算法能够同时降低包含日需求电荷和月需求电荷的电费账单。

英文摘要:

Utilities have introduced demand charges to encourage customers to reduce their demand peaks, since a high peak may cause very high costs for both the utility and the consumer. We herein study the bill minimization problem for customers equipped with an energy storage device and a self-owned renewable energy production. A model-free reinforcement learning algorithm is carefully designed to reduce both the energy charge and the demand charge of the consumer. The proposed algorithm does not need forecasting models for the energy demand and the renewable energy production. The resulting controller can be used online, and progressively improved with newly gathered data. The algorithm is validated on real data from an office building of IFPEN Solaize site. Numerical results show that our algorithm can reduce electricity bills with both daily and monthly demand charges.
