Title: Simulation-Based Performance Analysis of Communication-Enabled Smart Grid Applications

Conservation Voltage Reduction, or CVR, is an important technology for saving
energy. It aims to reduce the electricity consumption by lowering the service voltage
to the lowest possible values. lowering the voltage must be done in a controlled
manner in order to guarantee acceptable voltage at all customers along the distribution
feeder and under all load conditions.
The main goal of this work is to implement the necessary functions for simulating
a working version of a CVR application and testing its effect on energy consumption
along a distribution feeder. For this purpose, the communication framework
OMNeT++ and the power system simulator OpenDSS have been related in order
to control power system elements based on measured data transmitted over the
communication network. A wireless communication system has been implemented
in OMNeT++ between customer houses and the substation. Real-time voltage
values are measured periodically at the houses and sent to a controller unit at the
substation. Based on theses values the controller decides whether to lower the output
voltage at the substation’s transformer. In addition, radial distribution feeders
have been implemented to be a testing field for the CVR application.
The results showed that on a feeder of ten houses with residential loads an energy
saving of 3.4% could be achieved when applying CVR. The energy saving increases
significantly while decreasing the distance between loads or with the presence of
distributed generation.
