Projects

This page highlights selected projects that I have led or supported in academia, national laboratories, and DOE-sponsored programs.

Principal Investigator / Co-Principal Investigator

I led two Laboratory Directed Research and Development (LDRD) projects at PNNL and co-led one DOE project sponsored by the Wind Energy Technologies Office (WETO).

• PNNL-LDRD – Resilience Metrics for Cyber-physical (Power) Systems [$ 140k]

  This project develops outage-based, topological, and operating-envelope-based metrics to quantify resilience of cyber-physical power systems. The work uses EAGLE-I outage data and EIA annual disturbance event data, together with visualization tools and dynamic operating envelopes for extreme heat and cold events.

• PNNL-LDRD – Stability Characterization for Co-design of Power Electronics-dominant Power Systems [$ 200k]

  This project characterizes stability in power-electronics-dominant power systems and develops criteria to guide system co-design. It focuses on relationships among design variables, controller parameters, and stability margins.

• DOE-WETO – Stability-Informed Co-Design for Grid-Forming Inverters Deployment in IBR-Dominant Power Systems [$ 1.4 Million]

  Ongoing project. Technical details will be released as results become public.

Task Lead

I served as a task lead on the following DOE, DOD, and PNNL-sponsored projects.

• DOD-ESTCP – Model-Free Adaptive Control for Autonomous and Resilient Operation of Microgrids

  I led work on inverter P-Q control with trajectory tracking using physics-informed reinforcement learning, decentralized and coordinated V-f control for islanded microgrids, and virtual inertia scheduling for both bulk power systems and microgrids under static and dynamic security constraints.

• DOE – Large Scale Testbed for Cyber-physical Power Grid Simulation

  I contributed to the Large Scale Testbed (LTB) for cyber-physical power grid simulation, including development of the power-market simulator AMS. Team information is available on the LTB website.

• DOE – Advanced Grid Modeling of Future Power Systems

  I developed analytical EMT models of inverter-based microgrids and proposed a controller design method with guaranteed large-signal stability. The approach was validated through power hardware-in-the-loop experiments on the CURENT hardware testbed.

• DOE-PNNL – Energy Storage Portfolio

  I led several tasks on fast control and resilience analysis for energy storage systems and contributed to the PNNL Energy Storage Evaluation Tool (ESET).

• PNNL-LDRD – Control Oriented Models for Co-design Optimization

  I developed an EMT model of a 240-bus miniWECC system in PSCAD with offshore wind farms, IBRs, and HVDC/MTDC components. The model was converted from PSS/e using ETran, and I also built analytical and numerical wind-turbine models in Python with SymPy.

• PNNL-LDRD – Multi-Objective Co-design Optimization for Pareto-Set Identification

  I developed dynamic constraints for power-system co-design and planning problems, especially for offshore wind farms connected through HVDC/MTDC and equipped with frequency-support capabilities.

• PNNL-LDRD – Predictive Risk Informed Data-driven Resilient Controls

  I developed a dispatch-dynamics co-simulation platform for power systems that emulates denial-of-service and false-data-injection attacks, supporting batch data generation and computational attack detection.
