His innovative work has the potential to enhance the efficiency and reliability of renewable energy systems.
Latest Patents
Nan Xue holds a patent for a control design for a photovoltaic system in grid-forming operation for power grid support. This patent describes a grid-forming photovoltaic (PV) system and method that operates in both islanded connection and grid-connected modes. The invention includes an inverter that converts PV array voltage into a usable voltage for electric power system loads. An active power-frequency droop controller regulates a modulator that generates drive signals to operate the inverter. Additionally, a proportional integral controller generates a frequency shift value that adjusts the output of the active power-frequency droop controller, allowing for phase angle control in the modulation of the inverter drive signals. The control mode switch selects among various control modes for the proportional integral controller's operation, while a model-free control algorithm manages the control mode switch, including a control mode for synchronizing the PV system with the grid.
