Abstract

Coordinating residential building groups requires a hierarchical structure in which aggregate objectives and coupled constraints are incorporated into decision-making processes at different layers of the electric distribution system. Failure to handle these matters can raise issues, such as rebound peaks and contingencies. This paper proposes a Hierarchical Transactive Coordination Mechanism (HTCM) capable of dealing with residential consumers’ objectives/constraints and local and grid coordinators’ shared objectives/coupled constraints under a bottom-up strategy. Particularly, the proposed multi-level framework distributes local and grid coordinators’ shared objectives among consumers to flatten the aggregate consumption profile and minimize the aggregate energy cost at each level. The suggested scheme is enhanced by developing two additional operations. A gain-sharing technique is designed to fairly divide the total gain acquired by the grid coordinator across the hierarchy from higher to lower levels, successively. Besides, a coupled constraint-sharing method is devised to link these levels and fulfill the coupled constraints by revising consumers’ decisions. The proposed approach is applied to a society of buildings comprising Home Energy Management System (HEMS) groups with demand response-enabled electric Baseboard Heaters (BHs), and its effectiveness is investigated through different case studies. The results demonstrate that the recommended HTCM is able to improve the society’s aggregate power profile load factor by 89%, from 0.45 up to 0.85, and decreases its overall electricity cost by 6.2%.

通过基于多级共识共享的分布式 ADMM 实现分层交互式家庭能源管理系统组协调
协调住宅建筑群需要一个分层结构,将总体目标和耦合约束纳入配电系统不同层级的决策过程。如果不处理这些问题,就会引发反弹峰值和突发事件等问题。本文提出了一种分层交互协调机制 (HTCM),能够在自下而上的策略下处理居民消费者的目标/约束以及本地和电网协调者的共同目标/耦合约束。特别是,建议的多级框架将地方和电网协调者的共享目标分配给消费者,以扁平化总消费曲线,并最大限度地降低每个级别的总能源成本。建议的方案通过开发两个附加操作得到了增强。设计了一种收益分享技术,以公平分配电网协调器在整个层次结构中从较高层次到较低层次连续获得的总收益。此外,还设计了一种耦合约束共享方法,通过修改消费者的决策来连接这些层级并实现耦合约束。建议的方法被应用于由家庭能源管理系统(HEMS)组和需求响应电热板(BHs)组成的建筑群,并通过不同的案例研究考察了其有效性。结果表明,推荐的 HTCM 能够将社会的总功率曲线负荷率提高 89%,从 0.45 提高到 0.85,并将其总体电力成本降低 6.2%。
