Sensing, Communications and Monitoring for the Smart Grid
Abstract: With the increasing concern on environmental
factors, the reliability of the entire system, and
the electricity quality of service, power grids in
many countries are undergoing revolution towards a
more distributed and flexible “smart grid.” In the
development of the envisioned smart grid, the
situational awareness takes a fundamental role for
a number of crucial advanced operations, such as
power flow scheduling, dynamic pricing, energy
management, wide area control, wide area
protection etc. To fulfill the mission of
situational awareness across various entities in
the grid, more advanced sensing, communications
and monitoring techniques need to be introduced to
the existing power grid.

In this research, we will first address the issue
of battery power efficiency (BPE) in WSN which is
essential for the sensing system lifetime. We show
that the BPE can be improved either by selecting a
more battery-power-efficient modulation format or
by developing a cooperative communications scheme.
Then, to transmit the sensed data over the scarce
wireless bandwidth, we adopt cognitive radio as a
possible solution. To enable the cognitive radio
communication, we aim at improving both the
reliability and efficiency of the overall system
via cooperative spectrum sensing. With these
fundamental communication capabilities available
for the sensed data, we then investigate into the
wide area power grid monitoring based on
synchronized measurements from newly developed
devices such as phasor measurement unit (PMU),
mode meters and so on.
