Abstract

The invention is suitable for the technical field of uninterruptible power supplies, and provides a charging control method and device for an uninterruptible power supply of a new energy power generation system. The method comprises the following steps: acquiring the maximum allowable power and the input power of the uninterruptible power supply at the current moment, and the charging parameter of an energy storage device in the uninterruptible power supply at the current moment; subtracting the input power at the current moment from the maximum allowable power at the current moment to obtain surplus power at the current moment; determining the charging parameter adjustment amount of the energy storage device at the current moment based on the surplus power at the current moment and the parameters of the energy storage device; and adjusting the charging parameter of the energy storage device at the current moment based on the charging parameter adjustment amount at the current moment to obtain the charging parameter of the energy storage device at the next moment. By adjusting the charging parameters in real time, the power generation power utilization rate of the new energy power generation system can be improved.

Description

technical field [0001] The invention belongs to the technical field of uninterruptible power supplies, and in particular relates to a charging control method and device for an uninterruptible power supply of a new energy power generation system. Background technique [0002] At present, new energy power generation is an important source of electric energy in my country. In order to improve the power supply quality of new energy power generation systems, new energy power generation systems are usually used in conjunction with UPS (Uninterruptible Power System, uninterruptible power supply). The energy storage device in the UPS system can store part of the input electric energy for emergency use and improve the quality of power supply when the electric energy is sufficient. [0003] However, due to the unstable power generation of the new energy power generation system, the power entering the UPS system will also change in real time. For example, in a wind power system, the po...
