Distribution Grid Monitoring Based on Widely Available Smart Plugs
During the last few years, smart home devices have become increasingly
popular. Smart plugs, smart lights, and smart switches are now found in as many
as 37 percent of German households, and the popularity of these devices is
rising. Smart devices sometimes also integrate sensors for measuring voltage
and current. The increase in renewable generation, e-mobility and heat pumps
lead to scenarios for which the distribution grid was not originally designed.
Moreover, parts of the distribution grid are only sparsely instrumented, which
leaves the distribution grid operator unaware of possible bottlenecks resulting
from the introduction of such loads and renewable generation. To overcome this
lack of information, we propose a grid monitoring that is based on measurements
of widely available smart home devices, such as smart plugs. In the present
paper, we illustrate the collection and utilization of smart plug measurements
for distribution grid monitoring and examine the extent and effect of
measurement inaccuracy. For this evaluation, we analyze the measurements of
multiple commercially available smart plugs and test the effect of measurement
errors on the monitoring when using a single smart plug.Comment: 8 pages
