US Patent Issued to Hong Kong Applied Science and Technology Research Institute on Nov. 4 for "Distributed inertia-enhancement control method of the DC-bus voltage of a low-inertia DC microgrid" (Chinese Inventors)

ALEXANDRIA, Va., Nov. 6 -- United States Patent no. 12,463,433, issued on Nov. 4, was assigned to Hong Kong Applied Science and Technology Research Institute Co. Ltd. (Hong Kong, Hong Kong).

"Distributed inertia-enhancement control method of the DC-bus voltage of a low-inertia DC microgrid" was invented by Nibedita Parida (Hong Kong, Hong Kong) and Chun Kit Cheung (Hong Kong, Hong Kong).

According to the abstract* released by the U.S. Patent & Trademark Office: "A DC microgrid has increased DC bus voltage inertia without adding large physical capacitors. A Virtual Inertia Enhancement Controller (VIEC) of a DC-DC converter emulates a DC machine's mechanical inertia characteristics through a virtual capacitor which compensates for a power i...
