The integration of renewable energy resources and storage systems makes power delivery route reconstruction after the N-1 fault taking place more complicated. To solve the calculation problem of smart grid power transfer capability, the time-varying characteristics of renewable energy resources and storage systems were analyzed. Based on this, an N-1 recoverymodel was proposed on the base of the transfer capability index. Through making the calculation formula of the transfer capability index linear and adopting the artificial intelligence （AI） optimal algorithm based on topology simplification, the operation modes of the power grid, new energy generations and new energy storage systems can be optimized and the maximum power transfer capability of the grid can be achieved. Finally, taking an actual typical network as an example, the significant role of interconnection of renewable energy resources and energy storage devices for the improvement of N-1 recovery ability and the transfer of loads was analyzed. The power transfer capability index in quantitatively describing the self-healing feature was proved to be effective.
