Many challenges related to energy use and grid participation face the residential building sector and utilities that serve our homes today. To reduce energy consumption, increase grid service participation, and improve homeowner benefits, a solution is needed that can adapt itself to each home and homeowner/occupant, that can deliver both building and grid services with reliability and high availability, that can automate these operations to minimize cost and complexity of deployment, and that can provide both home data privacy and grid cybersecurity. We hypothesize that customer-oriented home automation can mutually satisfy home occupant/owner needs, reduce energy consumption, and deliver reliable grid services. This project seeks to develop innovative technology solutions that prove this hypothesis. The Home Battery System (HBS) is a technology package comprised of connected 'smart' appliances, rooftop solar photovoltaics, a home battery, and a coordinating smart controller. This system is envisioned, developed and demonstrated by the National Renewable Energy Laboratory (NREL), Bosch, ESCRYPT and Colorado State University (CSU). It is the result of three years of research by our diverse team. NREL developed the home automation controller, and performed simulation and laboratory evaluations of the HBS. Bosch developed and delivered most of the connected appliances used in the project, and provided technical and commercialization guidance. ESCRYPT led cybersecurity analysis and developed the cybersecurity layer. CSU provided leadership on preference elicitation methodologies.
