先前的工作表明，如果参考功率变化是高频的（几秒到几分钟），则建筑物供暖、通风、空调（HVAC）系统可以为电网提供辅助服务，而不会牺牲居住者的舒适度。本文讨论了当参考功率变化具有较低频率时，例如，几分钟到一个小时的时间。为此，所提出的控制系统使用两层架构。优化器基于负荷预测调度建筑物的基准制冷和制热功率。然后使用较低级别的控制器来跟踪预定的基线加上辅助服务参考信号。该时间表定期更新的基础上，室内测量，以确保服务质量，尽管负荷预测误差。该算法在模拟测试。结果表明，在满足舒适室内环境的前提下，商业建筑暖通空调系统可以在f ∈ [1/（1小时），1/（10分钟）]的频率范围内提供辅助服务。
Prior work showed building Heating, Ventilation, Air Conditioning (HVAC) systems can provide ancillary services to the power grid without sacrificing occupant comfort if the reference power variation is of high frequency (seconds to a few minutes). This paper addresses the question of how to do that when the reference power variation is of lower frequency, e.g., periods of a few minutes to an hour. The proposed control system to do so uses a two-layer architecture. An optimizer schedules the baseline cooling and heating power of a building based on load forecasts. A lower level controller is then used to track the scheduled baseline plus ancillary service reference signal. The schedule is periodically updated based on indoor measurements to ensure quality of service in spite of load forecasting error. The algorithm is tested in simulation. Results show that ancillary services in the frequency range of f ∈ [1/(1 hour), 1/(10 minutes)] can be extracted from commercial building HVAC systems while still maintaining a comfortable indoor climate.
