Abstract: Lower carbon emission is one of the near-term goals for our society. As promising solutions, renewables play critical roles in carbon emission reduction for energy systems and transportation sectors. More and more renewable systems will inevitably be connected to our grids. How to model, operate, and protect power electronics interfaced renewable systems has become a major problem that needs to be solved as soon as possible.
In this talk, I will mainly discuss the control and management of power electronics interfaced renewable systems covering primary, secondary, tertiary control, and monitoring perspectives. I will first introduce a Phasor Lock Loop (PLL) free primary control system for PV inverters. Then, a robust frequency support synthesis for wind turbine generators considering linearization-induced uncertainty will be discussed, followed by a brief discussion on optimization-based tertiary management. The development of a model-based online monitoring system for hybrid solid-state transformers (HSSTs) will be presented to finish the technical part of my presentation. The talk will be ended with discussions about my future research direction on power electronics modeling and control.
