摘要
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.关键词
