摘要:

当今世界对电力及其基本性质的需求不断增长,需要能够减少能源使用的智能家庭能源管理(HEM)系统。这涉及从能量消耗处于其最高时的一天的高峰时间到能量消耗相对较低时的一天的较低非高峰时段的负载调度,从而降低系统的峰值负载需求,这将因此导致更少的能量账单,并改善负载需求曲线。这项工作介绍了一种新的方法来开发一个学习系统,可以从经验中学习,将负载从一个时间实例转移到另一个时间实例,并实现最小化总峰值负载的目标。本文提出了一种用于需求响应的深度强化学习(DRL)模型,其中虚拟代理像人类一样学习任务。智能体在环境中采取的每一个行动都会得到反馈;这些反馈将驱使智能体学习环境,并在学习阶段的后期采取更明智的步骤。我们的方法优于国家的最先进的混合整数线性规划(MILP)的负荷峰值降低。作者还设计了一个智能体来学习同时最小化消费者的电费和公用事业公司的系统峰值负荷需求。所提出的模型进行了分析,从五个不同的住宅消费者的负载,所提出的方法增加了每个消费者的每月储蓄,减少他们的电费大幅减少,同时最大限度地减少系统上的峰值负荷时,所提出的方法处理的时移负载。

英文摘要:

The rising demand for electricity and its essential nature in today's world calls for intelligent home energy management (HEM) systems that can reduce energy usage. This involves scheduling of loads from peak hours of the day when energy consumption is at its highest to leaner off-peak periods of the day when energy consumption is relatively lower thereby reducing the system's peak load demand, which would consequently result in lesser energy bills, and improved load demand profile. This work introduces a novel way to develop a learning system that can learn from experience to shift loads from one time instance to another and achieve the goal of minimizing the aggregate peak load. This paper proposes a Deep Reinforcement Learning (DRL) model for demand response where the virtual agent learns the task like humans do. The agent gets feedback for every action it takes in the environment; these feedbacks will drive the agent to learn about the environment and take much smarter steps later in its learning stages. Our method outperformed the state of the art mixed integer linear programming (MILP) for load peak reduction. The authors have also designed an agent to learn to minimize both consumers' electricity bills and utilities' system peak load demand simultaneously. The proposed model was analyzed with loads from five different residential consumers; the proposed method increases the monthly savings of each consumer by reducing their electricity bill drastically along with minimizing the peak load on the system when time shiftable loads are handled by the proposed method.
