论文摘要
Smart Home Expliances可以计时并减少其功率需求，以帮助需求侧管理或允许使用有限的电源操作，例如在离网应用程序中。本文提出了一个调度过程，以启动具有随时间变化的确定性负载配置文件的设备。自触发的模型预测控制用于将家庭净电力需求限制在给定阈值以下。同时，与可变充电或热负载相比，确定性负载曲线更难安排，因为一旦不满足电源需求，系统故障就会发生。所提出的方案制定了负载转移时间作为连续优化问题的决策，并引入了不均匀的时间网格系统，以处理该分辨率的不同设备及其共识的优化。通过与混合成员MPC控制器的数值比较以及对三台家用电器和可中断的洗衣机进行数值比较来研究所提出方案的功效。
Smart home appliances can time-shift and curtail their power demand to assist demand side management or allow operation with limited power, as in an off-grid application. This paper proposes a scheduling process to start appliances with time-varying deterministic load profiles. Self-triggered model predictive control is used to limit the household net power demand below a given threshold. Meanwhile, deterministic load profiles are more difficult to schedule compared to variable charging or thermal loads because system failure will occur once power demand is not satisfied. The proposed scheme formulates the decision of the load shifting time as a continuous optimization problem, and an inhomogeneous time grid system is introduced to handle the optimization of different appliances and their consensus at this resolution. The efficacy of the proposed scheme is studied by numerical comparison with a mixed-integer MPC controller and by a case study of three home appliances and an interruptible washing machine.
