Latest Patents

Deng is named on 1 patent: “Method and System for Predicting Electrical State Quantity of Uninterruptible Power Supply (UPS) System, and UPS System Control Method and UPS System.”

The invention describes a method for predicting electrical state quantities in a UPS system and optimizing its control. It uses a discrete model to establish relationships between predicted dynamic variables and the switching states of power switches. A model predictive control (MPC) objective function is then constructed, and candidate switch states are evaluated to identify optimal switching decisions. The approach is intended to address challenges in coordinating and optimizing control across systems with multiple converters, while improving the operating efficiency of high-power UPS systems and the stability of their control.
