Latest Patent Applications
Zisen Qu has filed several significant patent applications, including:
1. **POWER SUPPLY SYSTEM AND GRID-FORMING CONTROL METHOD** - This application provides a power supply system and a grid-forming control method to increase the frequency synchronization speed of a grid-forming power generation device. The power supply system may include at least one new energy power generation device, which consists of a power converter and a control apparatus. The control apparatus outputs an output voltage phase of the power converter based on the difference between a target output parameter of the power converter and an output parameter at a point of coupling. It also adjusts the output voltage phase of the power converter when a phase difference of a voltage at the point of coupling within a threshold time exceeds a preset threshold.
2. **POWER CONVERSION SYSTEM AND POWER UPDATE CONTROL METHOD** - This application describes a power conversion system that includes N power conversion units and a control unit. The control unit can manage the operating modes of one or more target power conversion units in a control periodicity, switching between a PR mode and an MPPT mode. It updates a reference power based on the maximum power obtained in the MPPT mode, ensuring that the operating power of the target power conversion unit in the PR mode becomes the updated reference power, which is less than or equal to the maximum power. Additionally, the control unit maintains the operating mode of other power conversion units unchanged to prevent unnecessary mode switching.
Conclusion
Zisen Qu's innovative applications in power supply systems and control methods demonstrate his commitment to advancing energy technology. His work has the potential to significantly impact the efficiency of power generation devices in the future.
