摘要:

住宅负荷具有很大的潜力,以提高电力系统的效率和可靠性,通过需求响应(DR)计划。住宅DR的一个主要挑战是处理未知和不确定的客户行为。以往的研究多采用学习技术来预测用户的DR行为,而忽略了时变环境因素的影响,这可能导致预测不准确和负荷调整效率低下。在本文中,我们考虑住宅DR问题的负载服务实体(LSE)的目的是选择一个最佳的客户子集,以最大限度地提高预期的负载减少与财政预算。为了学习环境影响下的不确定客户行为,将住宅DR问题转化为一个上下文多臂强盗(MAB)问题,提出了基于Thompson抽样的在线学习选择(OLS)算法,该算法考虑了上下文信息,适用于复杂的DR环境.数值仿真结果验证了该算法的学习有效性。

英文摘要:

Residential loads have great potential to enhance the efficiency and reliability of electricity systems via demand response (DR) programs. One major challenge in residential DR is to handle the unknown and uncertain customer behaviors. Previous works use learning techniques to predict customer DR behaviors, while the influence of time-varying environmental factors is generally neglected, which may lead to inaccurate prediction and inefficient load adjustment. In this paper, we consider the residential DR problem where the load service entity (LSE) aims to select an optimal subset of customers to maximize the expected load reduction with a financial budget. To learn the uncertain customer behaviors under the environmental influence, we formulate the residential DR as a contextual multi-armed bandit (MAB) problem, and the online learning and selection (OLS) algorithm based on Thompson sampling is proposed to solve it. This algorithm takes the contextual information into consideration and is applicable to complicated DR settings. Numerical simulations are performed to demonstrate the learning effectiveness of the proposed algorithm.
