Current Research:


1- Cybersecurity of Smart Grids

I work on modeling false data injection attacks in large-scale smart grids with the main objective of transmission line overflow. These attacks are normally targeted and are aimed at manipulating the advanced metering infrastructure (AMI) readings to bypass the bad data detection algorithms used in AC and DC state estimation methods.

2- Smart Grid Dynamics

I work on modeling and controlling of power electronics-based converters in smart grids and microgrids (DC or AC). This includes but not limited to :

a) Control of converters for high voltage direct current (HVDC) transmission systems in weak ac grids

b) Impedance modeling of converters in smart grids

c) Impedance modeling of modular multi-level converters (MMC)

d) Dynamic phasor modeling of microgrids and electric machines

e) State-space modeling of power apparatus with power electronics converters

3- Distributed Control in Cyber-Physical Systems

I work on designing distributed controllers for cyber-physical systems (smart grids) and their components such as energy storage, photo-voltaic (PV) or wind farms. This includes but not limited to :

a) Distributed cooperative control of energy storage devices using consensus theory

b) Distributed consensus design for heterogeneous energy storage devices

c) Primary and secondary voltage/frequency control of energy storage devices using consensus theory

d) Cooperative control of distributed energy storage devices in presence of communication and self delays


4- Dynamic Simulation of Cyber-Physical Power Systems

In this research area, I focus on real-time and hardware in the loop (HIL) simulations of power electronics converters such as voltage source converters or modular multi-level converters applied to distributed generation systems and high voltage DC transmission systems. Simulations are mainly carried out using MATLAB software or Real-time simulators.


5- Hardware Development of Cyber-Physical Power Systems:

In this research area, I work on developing various converter types including voltage source converters (VSCs) for renewable energy integration and various DC/DC converters using Gallium Nitride and Silicon Carbide (SiC) technology. We often use Texas Instrument controllers for digital logic design and develop a custom-built printed circuit board (PCB) for each converter technology.


6- Optimization and Security of Energy-Water Microgrids

In this research area, I optimize the resource allocation in an energy-water microgrid by minimizing the cost of operation of generation resources in a microgrid (including conventional generation units, renewable sources, and energy storage units) and providing demand response on the building sector (using intelligent building energy management system) and water distribution units (by minimizing the energy consumption of pumps and maximizing the reliability of water supply).
