The invention discloses a test method used for a wind storage access system. Through carrying out a secondary system test, an energy storage subsystem test and a background joint debugging test on the wind storage access system, whether an energy storage cell body of the wind storage access system operates normally is verified and whether the wind storage access system carries out charging and discharging on the cell is verified too; a basic function of outputting reactive power to a power grid and the like are possessed; a correlation technology index and the like of the wind storage access system during an operation process are verified. By using the method of the invention, a comprehensive test can be effectively performed on the wind storage access system and technology guarantee is provided for normal working of the wind storage access system.
