Research
(Some links may be broken
due to ongoing maintenance work on this website)
I am currently doing
research in the broad area of local area power and
energy systems (i.e., distributed generation
or micro-grids) both at a component
level studying power electronics interfaces, and
at a system level through controls analysis,
planning and performance improvements in terms
of reliability, operational flexibility, and
efficiency. I am also working in
customer-oriented smart grid technologies and
applications.

publications information and presentations
please click

I am also interested in energy security and
resilience by studying the effect of natural
disasters on critical power infrastructure.
Particularly information and communications
technology systems. Information and some
photos from my field damage assessments
after natural disasters can be accessed by

A compilation of my publications
about the impact of natural disasters on
power and communications infrastructures
since 2005 and planning for secure power
supply can be downloaded from here
(80 MB pdf file)
or by clicking on the image below
I also prepared a document that can
be accessed by clicking
here, summarizing the lessons
from
my
damage assessments with a focus on Superstorm
Sandy. This document was presented at the
FCC's Network Resiliency Workshop of 2013, in
Brooklyn, NY.
Some of my current and past research topics are:
- Local area power and energy systems
(microgrids) architectures and control
- Autonomous and de-centralized controls for
microgrids
- Stability analysis
- Hybrid controllers for grid connected and
grid islanded modes.
- Power infrastructure in natural disasters
(click on any of the disaster logos above to
see pictures from my damage assessments) and
use of microgrids for improved power supply
availability in such events. NSF
CAREER award #0845828.
- Availability model for microgrids
including lifelines, renewable and
non-renewable power sources, and energy
storage.
- Planning of microgrids for enhanced
resilience to natural disasters.
- Characterization of power grids
performance.
- Characterization of interdependencies
among critical infrastructures (DTRA Award #
HDTRA1-14-1-0021) - quantification based on
energy storage.
- Interactions between microgrids and the
power grid with focus on "smart-grid'
applications.
- Home and load energy management. Load
disaggregation
- Impact of high PV penetration.
- Multiple-input dc-dc converters.
- Circuit topology design
- Control
- Multiple-input multiple-output converters
for power routing (active power distribution
nodes) applications.
- Datacenters and communications power
infrastructure.
- Increased used of renewable energy sources
in wireless communication networks through
microgrids (NSF
CyberSEES award # 1331788)
- Higher-voltage dc
- Fault management
- Constant-power loads control.
- Boundary and linear controllers for
converters with constant-power loads.
- Rectifiers operation with constant-power
loads.
- Interfaces and controls for photovoltaic
systems.
- Maximum Power Point Trackers
- Electric vehicles
