Abstract

The technology of grid-forming energy storage can form a voltage source

which can support the stable operation of large power grids. The technology of grid-forming energy storage is an effective means to support the stable operation of high proportion of new energy connected to the grid. Based on this

the operation mechanism of grid-forming energy storage to support the stability of high proportion of new energy connected to the grid is analyzed. According to the principle and characteristics of grid-forming energy storage technology

five commonly used technologies to improve the stability of the grid are compared and. A model building idea of grid-forming energy storage system considering multi-time-varying parameters is proposed. Moreover

the scheme of grid-forming energy storage technology supporting high proportion of new energy grid-connected and the mechanism analysis of massive grid-forming energy storage equipment grid-connected oscillation is proposed.In addition

the system impedance dynamic identification technology based on signal injection is studied

and then the impedance reconstruction technical route of massive grid-forming energy storage equipment grid-connected system is proposed.
