Consumer systems for home energy management can provide significant energy saving. Such systems may be based on nonintrusive appliance load monitoring (NIALM), in which individual appliance power consumption information is disaggregated from single-point measurements. The disaggregation methods constitute the most important part of NIALM systems. This paper(More)
Implementation of smart grid provides an opportunity for concurrent implementation of nonintrusive appliance load monitoring (NIALM), which disaggregates the total household electricity data into data on individual appliances. This paper introduces a new disaggregation algorithm for NIALM based on a modified Viterbi algorithm. This modification takes(More)
A new method is proposed for monitoring miscellaneous and electronic loads (MELs) in a household. In this method, the current signal obtained at a main breaker or circuit level is disaggregated by detection of transients and classification of the waveforms. The classification is realized by probabilistic fusion of a harmonics-based classifier and a(More)
Home energy management systems (HEMS) can reduce energy consumption while maintaining comfort. However, HEMS suffer from slow adoption and unproven energy savings. As intelligent automation and persuasive design features are increasingly added to HEM products, many research questions remain regarding their efficacy. We present the FRESH research platform to(More)
Communicating thermostats (CTs) can provide a stream of home data, e.g., room temperature and status of heating, ventilation and air conditioning (HVAC) system to participating utility companies. We show how these data can be used to estimate physical home parameters that represent such major categories of home energy performance as wall insulation, air(More)
We present a novel framework — the SunDial system — intended to enable integration of high-penetration commercial and utility-scale photovoltaic (PV) plants by a combination of load and energy storage management. Rather than relying on controllable loads from disparate individual buildings, SunDial uses a Facility Load Aggregation and(More)
