Problems solved by technology
Among them, the independent user energy storage system is not smooth in the process of mains switching, and is prone to short-term output interruptions, which affects the power supply safety of equipment and causes economic losses in production
The backup time of the independent UPS system is short, and the overall utilization rate is not high
However, the high-voltage UPS energy storage system has high investment costs, poor applicability to small and micro enterprises and household scenarios, and a long payback cycle
Therefore, there are problems such as poor applicability, high cost and unstable power supply in the existing technical solutions

The invention discloses a hybrid power supply system and method based on household and UPS, and the method comprises the following steps: obtaining power grid state data of a user, charge state data of a first battery pack, and charge state data of a second battery pack, wherein the capacity of the first battery pack is greater than that of the second battery pack; obtaining photovoltaic power supply input data; charging and discharging the first battery pack and the second battery pack according to the acquired state-of-charge data of the first battery pack and the second battery pack; and supplying power to a load or switching a power supply according to the acquired state-of-charge data of the first battery pack and the second battery pack, the photovoltaic power supply input data, theuser power grid state data and the load output data. According to the invention, by setting the modes of large-capacity battery pack power supply and small-capacity battery pack buffer power supply switching, on one hand, the power supply safety is improved, and on the other hand, the battery capacity is reasonably utilized to facilitate improvement of economic benefits.
Description
Technical field [0001] The invention relates to the field of power supply, in particular to a hybrid power supply system and method based on household and UPS. [0002] technical background [0003] The prior art backup power solutions mainly include the following three types: independent user energy storage systems, independent UPS systems, and high-voltage UPS energy storage systems. Among them, the independent user energy storage system is not smooth in the process of city power switching, and it is prone to short-term output interruption, which affects the safety of equipment power supply and causes economic losses in production. The independent UPS system has a short backup time and the overall utilization rate is not high. The high-voltage UPS energy storage system has high investment costs, poor applicability to small and micro enterprises and household scenarios, and a long return period. Therefore, the existing technical solutions have problems such as poor applicability...
