In order to improve the reliability of microgrid power supply, this paper proposes a set of black-start scheme for the isolated microgrid. Based on the analysis of the characteristics and control of microsources, and the comparison of black-start capabilities of them, the selection principle of microsources in the process of black-start is established and the control requirements of them with and without black-start capabilities are expressed. Moreover, this paper analyzes the serial and parallel restoration strategy of the microgrid black-start and presents that the parallel strategy with high speed is more appropriate for the process. At the same time, the detailed operation procedure of black-start is formulated. The control models of microsources and the simulation model of microgrid are built with Matlab/Simulink, and the simulation results verify the feasibility of the microgrid black-start scheme and the operation procedure.
