The invention belongs to the technical field of new energy power generation and power supply, and specifically relates to a new energy power generation collaborated energy storage inverter system. According to the invention, a processing link is collected for electrical parameters of new energy power generation and inverter power generation and power supply through adopting a specially designed system, a battery energy storage subsystem charge-discharge complementary power instruction is generated in real time according to power changes of new energy power generation and inverter power generation and power supply and requirements of the grid-connected power fluctuation amplitude, and the power of an energy storage inverter is regulated, thereby solving fast response, enabling an energy storage system to perform complementary charge and discharge on new energy power generation and inverter power supply in a synchronous mode, and achieving the purposes of coordinated operation of new energy power generation and inverter power generation and power supply and power fluctuation suppressing. The new energy power generation collaborated energy storage inverter system realizes millisecond-level fast response, achieves an effect of suppressing the power fluctuation of collaborated new energy power generation and power supply in real time, performs complementation on the new energy powerby efficiently using the energy storage system and the fluctuation at a low cost, achieves the innovation and application of power fluctuation suppressing and has obvious beneficial effects.
