MULTI-MODAL DATA IMPROVEMENT FOR POWER DISAGGREGATION SYSTEMS

摘要

The present invention relates to a method and apparatus for disaggregation of energy consumption in a power distribution system. The basic idea is to look at the overall energy consumption and recognize the contributions of each single electrical device (120), e.g. for the purposes of providing a breakdown of energy consumption to users. Disaggregation is assisted by usage of multi-modal system data coming from various external data sources (106-1 to 106-n), such as building management systems and/or IT infrastructure, to relate activities of people or devices to changes in power consumption.
