Query: Constructing dynamic residential energy lifestyles using Latent
  Dirichlet Allocation   The rapid expansion of Advanced Meter Infrastructure (AMI) has dramatically
altered the energy information landscape. However, our ability to use this
information to generate actionable insights about residential electricity
demand remains limited. In this research, we propose and test a new framework
for understanding residential electricity demand by using a dynamic energy
lifestyles approach that is iterative and highly extensible. To obtain energy
lifestyles, we develop a novel approach that applies Latent Dirichlet
Allocation (LDA), a method commonly used for inferring the latent topical
structure of text data, to extract a series of latent household energy
attributes. By doing so, we provide a new perspective on household electricity
consumption where each household is characterized by a mixture of energy
attributes that form the building blocks for identifying a sparse collection of
energy lifestyles. We examine this approach by running experiments on one year
of hourly smart meter data from 60,000 households and we extract six energy
attributes that describe general daily use patterns. We then use clustering
techniques to derive six distinct energy lifestyle profiles from energy
attribute proportions. Our lifestyle approach is also flexible to varying time
interval lengths, and we test our lifestyle approach seasonally (Autumn,
Winter, Spring, and Summer) to track energy lifestyle dynamics within and
across households and find that around 73% of households manifest multiple
lifestyles across a year. These energy lifestyles are then compared to
different energy use characteristics, and we discuss their practical
applications for demand response program design and lifestyle change analysis.
