2019 2020, all homes in the UK will have a smart meter installed. DECC is working on the spec for these meters at the moment. In the context of my PhD on smart meter disaggregation, I have several questions I need to answer about these specs:
- exactly which power metrics will UK smart meters expose to the home area network (HAN)? (just active power? And reactive power? Can we distinguish between leading vs lagging? THD?)
- report rate? (one measurement every 5 seconds? The 2011 "Functional Requirements Catalogue" said "The smart metering system shall support capture of consumption and demand data at 5 second intervals."
- and how could a disaggregation system read these data?
The Smart Meters Equipment Tech Spec Version 2 (SMETS2) was released in Jan 2013. Some useful paragraphs for those of us interested in disaggregation:
