The following thesis is an investigation on adopting Power Line Communication (PLC) technology from AC (Alternating Current) lines to DC (Direct Current) lines and possibility to apply it on automotive applications. Prototype modules are built with existing PLC chip to verify communication performance over the battery DC lines. In order to ensure reliable data transmission over the vehicle DC power lines, research is expanded to analyze the characteristics of vehicle DC-bus network. Typical automotive components are selected and tested for interference and noise analysis. Detailed studies on impulsive noise and its statistic distribution are presented. As well, the characteristics of Lead-acid battery are reviewed on the possible impacts to carrier frequency. Overall, PLC technology is promising for automotive applications. But the test result shows there is limitation to apply existing PLC product to automotive DC applications. Directly adopting the control method used in AC application to DC is not trivial. Further study and future research areas are recommended to be conducted to mature the PLC technology being utilized on automotive systems.

Building real Smart Metering and Smart Grid networks is very expensive and time-consuming and also it is impossible to install different technologies in the same environment only for comparison. Therefore, simulation and experimental pilot measurements are an easy, economical, and time-affordable solution for a first comparison and evaluation of different technologies and solutions. The local area networks (LAN) are the core of Smart Metering and Smart Grid networks. The two predominant technologies are mostly sufficient for LAN networks, Power Line Communication (PLC), and radio frequency (RF) solutions. For PLC it is hard to allow prediction of the behaviour. Performance assessment for point-to-point connection is easy, but for complex PLC networks with repeaters it is quite expensive. Therefore, a simulation is an easy, fast, and cheap solution for understanding the grid configuration, influence of particular topological components, and performance possibilities. Simulation results can, thus, provide material for the design of a telecommunication infrastructure for Smart Metering. This paper presents results of such a simulation study. It is based on realistic PLC channel model implementation in Network Simulator 3, our modification and extension of this implementation for our use case scenario. It uses Shannon’s formula to calculate theoretical maximum channel capacity. In particular, it provides channel capacity and achievable distances of broadband PLC (BB-PLC). In this article we also exploit our novel idea of simple performance assessment of broadband PLC communication via simulation. It is supposed to be used to understand, evaluate, and test the grid configuration before deployment.
