Research Interests
My research activities span all branches of control theory with applications to electric power systems. In NCSU I am a part of the FREEDM Systems Center, currently investigating several system and control-theoretic research problems for the US power grid using Wide-area Synchrophasor (WAMS) technology, and its integration with renewable energy sources such as wind energy.
Some specific topics of research that my group is currently looking into are:
1. Wide-area Phasor Measurement Technology –Model identification, grid stress assessment, modal analysis, and wide-area control of power system networks using Synchrophasor measurements. (Supported by NSF, 2010-2013).
2. Disturbance Propagation in Power System Networks – Developing methods for pattern recognition and PDE identification from power system disturbance data collected over wide geographic spans.
3. Equivalent Modeling & Control of Wind Farms – Constructing dynamic equivalents of large wind farms using Synchrophasor data available from high-voltage terminal buses of such farms.
4. Identification & Protection of Power Systems from Cyber-attacks – Using graph-theoretic algorithms for IT-security of distributed power system networks against manipulative cyber-attacks.
Detailed description of my ongoing projects and collaborations can be found at
my group website: www.ece.ncsu.edu/power
An introductory research brochure for my PhasorLab, featuring several
recently procured PMUs, can be found here.
