Test method and system for improving support capability of new energy access to power grid through energy storage

The invention relates to the field of electrical performance testing, in particular to a testing method and system for improving the supporting capacity of new energy access to a power grid through energy storage. The method comprises the following steps: according to simulation parameters corresponding to each simulation model determined by a target test item, executing parameter regulation and control operation on each simulation model; simulating fault information corresponding to the target test item based on each simulation model, and configuring the working state of the physical terminal according to the fault information; determining a fault type and a fault level of the physical terminal based on the operation parameters acquired from the physical terminal; determining a corresponding fault processing strategy according to the fault type and the fault level; controlling the physical terminal according to the working state information flow signal of the fault processing strategy, and controlling the ph
