Abstract: Plug load audit in a typical office environment is not only challenging, but also expensive and time-consuming. The proposed data-driven framework aims at improving existing state-of-the-art protocol to monitor plug loads in every individual workstation. It measures the aggregated energy signature of multiple office appliances (e.g. desktop PC, monitor, laptop PC and multi-functional device) and employs intelligent algorithms to disambiguate operational modes of every individual ground-truth appliance. It reduces both capital cost in metering every appliance and also offers valuable insights from single-point measurement. The analysis is driven based on a large repository called OPLD developed for this purpose. A novel idea of transforming temporal energy signatures into a massive dictionary of Context-Free-Grammar words is implemented within this framework. Such implementation facilitates developing multiple load disaggregation algorithms based on substring similarity. Several potential aggregate appliance use-cases are analyzed. The results of deep disaggregation are benchmarked and validated across multiple algorithms.
