This paper focuses on the switching stability control of microgrid in the process of grid-connected and island operation. Firstly, the grid-connected operation model and island operation model are established, and they are regarded as two subsystems of switched system; then the cross backstepping method is used to design the switching controllers of the two subsystems, and the common Lyapunov function is constructed at the same time. Finally, matlab simulation verifies the effectiveness of the designed controller and switching law.
