Over the past decades, there have been an increased number of the Internet of things (IoT) sensors deployment in electrical distribution networks. This paper proposes a statistical approach to establish the correlations between estimated occupancy within physical proximity and the associated loads. This study includes a sensitivity analysis of occupancy and how it influences load consumptions. First, a statistical distribution with a regression model is formed to correlate these two heterogeneous properties, in terms of occupancy and power (OP) consumption, to generate a time-dependent model. Since model deviations from an estimate based on regular pattern as a time-varying process with the curve fitting, the possible structural deviations in real-time demand are then considered to update the initial regression model using new real-time estimates and observations obtained every demanded time duration. The dynamic profile of human movements and their load characteristics are established with parametric adjustments and observed using the case studies.
