Responsibilities
Develop EMT models in real-time simulators and hardware-in-the-loop platforms for high-power converters interfacing various MW-scale distributed energy resources
Develop advanced control methods for high-power converters at different timescales and layers, such as grid-forming control and grid-support functions to improve system performance during transients and steady state and also for non-ideal grid conditions (unbalanced loading, faults, etc.)
Validate medium-voltage, high-power converter controller and power hardware using the medium-voltage power electronics testing capability at NREL ESIF facility
Develop decentralized control techniques to improve the scalability of the modular power converters (e.g., CHB-DAB and MMCs), including PWM interleaving, inter-isolation-barrier decentralized control, communication-less power sharing, and decentralized fault-tolerant control
Collaborate with experts at NREL and industry stakeholders
