Community-scale residential energy demand simulation for smart-grid applications

This study reports the application of a stochastic simulation model that estimates community-scale residential electricity demand and photovoltaic (PV) generation to simulate the voltage of medium- and low-voltage distribution networks. This model enables the evaluation of the impact of PV diffusion and energy management technologies using, for example, battery and electric vehicles, on voltage management. This study shows a case study in which the developed model was applied to a community consisting of 732 households to estimate the network voltage and power generation loss that occurs when the voltage exceeds the legal limit. This study also discusses challenges in modeling the high-temporal-resolution energy demand of residential buildings.
