Smart Grid Communications by Prof. Brian L. Evans, UT Austin
Friday, Dec 14, 2012
1 p.m. - 2 p.m. Location: ECSS 3.503




Smart Grid systems intelligently monitor and control energy flows in order to improve efficiency and reliability of power delivery. A local utility would receive customer load profiles from smart meters, and adjust power generation and energy distribution accordingly. Smart meters could transmit usage data over powerline or wireless links once per minute.

Smart Grid communication over outdoor power lines is attractive because it uses existing infrastructure. However, it is limited by the strong impulsive noise, esp. from power electronics and wireless signals, within the 3-500 kHz transmission band.

In improving reliability of outdoor powerline communication (PLC), we derive impulsive noise models using field measurements, develop receiver methods to mitigate the noise, and implement those methods in our real-time testbed. One of our impulsive noise models has been adopted by the IEEE 1901.2 PLC standard.

Research is supported by SRC GRC ICSS Task 1836.063 with sponsors Freescale Semiconductor, IBM and Texas Instruments. The PLC project Web site:



 Prof. Evans researches embedded real-time digital signal processing for communication and image processing systems. His research group develops theory, algorithms, design methods and full-system testbeds. He has published 200+ peer-reviewed journal/conference papers, and graduated 20 PhD and 9 MS students. He was elevated to IEEE Fellow "for contributions in multicarrier communications and image display". He received a US NSF CAREER Award.
