Title:
CHARGING CONTROL METHOD AND DEVICE FOR UNINTERRUPTIBLE POWER SUPPLY FOR NEW ENERGY POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/000581
Kind Code:
A1
Abstract:
The present application is applicable to the technical field of uninterruptible power supplies, and provides a charging control method and device for an uninterruptible power supply for a new energy power generation system. The method comprises: acquiring maximum allowable power and input power of an uninterruptible power supply at current time, and charging parameters of an energy storage device in the uninterruptible power supply at the current time; subtracting the input power at the current time from the maximum allowable power at the current time to obtain surplus power at the current time; determining a charging parameter adjustment amount of the energy storage device at the current time on the basis of the surplus power at the current time and energy storage device parameters; and adjusting the charging parameters of the energy storage device at the current time on the basis of the charging parameter adjustment amount at the current time to obtain the charging parameters of the energy storage device at the next time. According to the present application, by adjusting the charging parameters in real time, the power generation power utilization rate of the new energy power generation system can be improved.
