US Patent Issued to HITACHI ENERGY on Aug. 12 for "Parameterized potential functions for equality constraints" (North Carolina Inventor)

ALEXANDRIA, Va., Aug. 12 -- United States Patent no. 12,386,328, issued on Aug. 12, was assigned to HITACHI ENERGY LTD (Zurich, Switzerland).

"Parameterized potential functions for equality constraints" was invented by Xiaoming Feng (Cary, N.C.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Prior methods of state estimation, based on a constrained optimization problem with equality and/or inequality constraints, rely on penalty-based heuristics which can produce very large weight values, resulting in ill-conditioning of the gain matrix. Disclosed embodiments of state estimation convert the constrained optimization problem into an unconstrained convex optimization problem in which violated equality and/or ine...
