The invention discloses a method for analyzing charge and discharge capacity of large-scale energy storage clusters. The method comprises the following steps of respectively computing specific parameters of pre-selected energy storage power station clusters according to the telemetering amount and the remote signaling amount which are uploaded by each energy storage power station, and determiningmaximum available time meeting set charge and discharge power and maximum available charge and discharge power meeting set charge and discharge time of each energy storage power station cluster according to the computed specific parameters of the energy storage power station cluster. According to the method, the charge and discharge capacity of each energy storage set as a whole of energy storageresources is analyzed, and a powerful data support is provided for the power control characteristics after the large-scale energy storage power stations are connected to a power grid, so that the control is more effective and
