New energy power supply system

The invention relates to the technical field of power supply, and discloses a new energy power supply system, which comprises a conversion power generation module, a standby power generation module, a power storage module, a power grid module, a power quality evaluation module, an identification module for identifying the power generation quality of a target module and a switching module for cutting off the power connection of the target module, if the conversion power generation module breaks down, the diesel power generation module can continue to supply electric energy, and continuous supply of the electric energy is further guaranteed; in addition, the power storage module can store redundant electric quantity and supply electric energy temporarily when the conversion power generation module and the standby power generation module fail, so that power shortage shutdown of the power load is avoided comprehensively. The electric energy evaluation module can automatically evaluate the power supply quality of
