CSR: EAGER: Design and Implementation of a Fine-Grained Appliance Energy Profiling System for Green Building

绿色建筑应用需要通过非侵入式负载监控（NILM）技术来高效且细粒度地确定各种消费级电器的功耗模式，以将需求响应模型有效地适配和渗透到消费级电器。在用于智能建筑能量管理的消费级电器处广泛采用这种需求响应策略的关键抑制因素是智能插头不能有效地确定、控制或推断串联的多个设备的功耗模式。 在实践中，部署基于智能插头的NILM并获取大量设备的低电平功率测量通常是困难的或不可能的，这是由于部署复杂性和设备的变化特性，因此必须在电路级采用，并通过结合新的基于使用的测量和基于概率水平的分解算法来推断。但是，部署非侵入式负载监控算法的挑战涉及分解单个设备？的消耗，以及建模和合并基于使用的预测。因此，在这个项目中，我们将专注于先进的机器学习和数据分析算法，捕获基于测量的方法和电路级NILM与自主分析和预测逻辑，以实现灵活和可替代的智能插头的部署和未来DR模型在绿色建筑应用的可发展性。

Green building applications need efficient and fine-grained determination of power consumption pattern of a wide variety of consumer-grade appliances through non-intrusive load monitoring (NILM) techniques for an effective adaptation and percolation of demand response model down to the consumer level appliances. A key inhibitor to the widespread adoption of such demand response policy at the consumer grade appliances for intelligent building energy management, is the inability of smart plug to efficiently determine, control or infer the power consumption pattern of multiple devices in tandem. In practice, deploying smart plug based NILM and acquiring the low-level power measures of a large number of devices is often difficult or impossible due to the deployment complexity and varying characteristics of devices and thus must instead be employed at the circuit-level and inferred through the incorporation of novel usage-based measurement and probabilistic level-based disaggregation algorithm. But the challenges in deploying non-intrusive load monitoring algorithm involve disaggregating individual device?s consumption from the aggregate power measurement, as well as modeling and incorporating the usage based prediction. Thus in this project we will focus on advanced machine learning and data analytics algorithms that capture the measurement based approach and circuit level NILM with the autonomous profiling and prediction logic to enable the deployment of flexible and fungible smart plug and the evolvability of future DR model in green building applications.
