Latest Patents

Chen’s listed patents address two related challenges in independent microgrids: suppressing electrical oscillations and coordinating power sources during connection.

“Island Microgrid System, and Interactive Oscillation Suppression Method and System Therefor” describes an island microgrid that combines source-side and load-side virtual synchronous machines to provide virtual inertia and damping. The invention uses d-axis inductive-current feedforward control and d-axis voltage-feedback control to reshape the virtual synchronous machines’ impedances and reduce their amplitudes. These measures are intended to suppress low-frequency interactions and address oscillations in alternating-current island microgrids composed of multiple source-load virtual synchronous machines.

“Diesel-Storage Independent Microgrid and Virtual Dynamic Synchronous Control Method and System Therefor” concerns synchronization between a diesel generator and an energy-storage converter. It introduces pre-synchronization phase-angle compensation and adaptive dynamic synchronous torque into the converter’s control system. The phase-angle compensation helps align the generator and converter before parallel connection, reducing current impact during connection. After connection, the adaptive torque adjusts the converter’s virtual torque in response to the components’ accelerations, even when the diesel engine’s inertia parameter is treated as a black box.
