Latest Patents

Yao Xu holds a patent for an "Adaptive controller for STATCOM to enhance voltage stability." This invention comprises an outer voltage regulator loop and an inner current regulator loop. Each loop features a proportional integral controller. The outer loop adjusts the proportional and integral control gains of the voltage regulator, while the inner loop modifies the proportional and integral parts of the current regulator gains. The automatic adjustment of these regulator gains is adaptively determined, ensuring that the voltage at the controlled bus follows a desired voltage reference curve over time. This system returns to a desired steady-state condition under various disturbances, such as changes in load and/or transmission network. The adaptive controller achieves a plug-and-play feature for a STATCOM without requiring human intervention.
