Thermostatically controlled loads such as refrigerators are exceptionally suitable as a flexible demand resource. This article derives a decentralized load control algorithm for refrigerators. It is adapted from an existing continuous time control approach, with the aim to achieve low computational complexity and an ability to handle discrete time steps of variable length—desirable features for embedding in appliances and high-throughput simulations. Simulation results of large populations of heterogeneous appliances illustrate the accurate aggregate control of power consumption and high computational efficiency. Tracking accuracy is quantified as a function of population size and time step size, and correlations in the tracking error are investigated. The controller is shown to be robust to errors in model specification and to sudden perturbations in the form of random refrigerator door openings.

恒温负载总负载控制的低复杂度分散算法

诸如冰箱之类的恒温控制负载特别适合作为灵活的需求资源。本文推导了一种冰箱的分散负载控制算法。它改编自现有的连续时间控制方法，旨在实现低计算复杂度和处理可变长度离散时间步长的能力——这是嵌入电器和高吞吐量模拟的理想特性。大量异构电器的仿真结果说明了功耗的精确聚合控制和高计算效率。跟踪精度被量化为人口规模和时间步长的函数，并研究了跟踪误差的相关性。
