Power Systems Simulation
I have explored different methods for the numerical simulation of power systems. Some of the work includes high performance computing techniques in large power systems, simulations on certain hardware platforms with FPGAs, and adjustments to a numerical integration method to achieve faster simulation times. Finally, in order to clarify some key concepts, I have co-authored a paper which considers a geomettric interpretation for reference frames and the transformations between them.

Parameter Estimation with Devices in Microgrids
As part of my PhD research, I developed a hybrid algorithm for parameter estimation (HAPE) which is used to estimate the parameters in simulaiton models for dynamic constant power loads (DCPLs) and diesel generator sets. In each piece of work, the HAPE considers non-invasive measurement waveforms (voltage and current). These measurement waveforms are to be matched with corresponding waveforms from a similar simulation. The HAPE is executed in a massively parallel fashion on a supercomputing platform maintained by the Lincoln Laboratory Supercomputing Center (LLSC).

Reconfigurability and System Stability in Microgrids
I am interested in the operation of low voltage microgrids. In some of my research I have investigated stable operational states which are reconfigurable and robust. More specifically, I am interested in a single-family home as a case study- one which includes 1 or 2 electric vehicles, a rooftop solar system, and perhaps other sub-systems which may be installed inside a modern all-electric home.

Power Electronics
In order to enable flexible grid topologies for single phase systems, the design, operation, and control of microgrids
both globally and locally become important. Bi-directional power flow, seamless operational transitions in the midst of disturbances
and the integration of new technologies are all relevant in modern power systems. To enable such important functionality, we may explore new additions to the rectifier and inverter controllers
in an AC-AC converter with a topology containing few switches.
In addition to some of these modifications, I am also interested in some of the enhancements to conventional control methods which can allow for versatile operation in power systems.
