Below is a compilation of projects that I have worked on over the years.

Projects

System Strength Sensitivity

Derived metrics from the sensitivity of system modes to perturbations in power injections and admittances.

System Strength Review

Reviewed metrics for quantifying the strength of power systems with inverter-based resources.

STABILITY: Grid Survival Sim

Created a browser based game for a general audience to better understand power system stability and control.

Safe Trajectory Gradient Flow

Developed a control approach applying safe gradient flow to a trajectory optimization problem for IBR control.

Safe Control of IBRs with Current Limits

Developed a control barrier function safety filter for the safe and stable control of IBRs with current limits.

Control of IBRs with Current Limiters

Analyzed the stability of inverters with a current limiter controlled as voltage sources.

AC-OPF Dataset Creation

Developed code for the efficient creation of datasets for machine learning AC optimal power flow applications.

Energy Storage Dispatch Assumptions

Researched the impact of energy storage dispatch assumptions on power system resource adequacy assessment.

E-Bike Power Electronics

Designed power electronics hardware and controls for an e-bike which powered an AC motor from a battery.
