Abstract: In order to further improve the reliability of microgrid power supply, based on the microgrid of wind, photovoltaic, diesel generator and energy storage, fully considering the characteristics of various micro-sources, this paper compared and analyzed the selection of power supply in black-start of microgrid. The diesel generator was chosen as the black-start power supply. This paper analyzed the parallel and serial restoration strategy of the microgrid black-start, proposed an improved black-start strategy for serial restoration of microgrid and formulated the detailed operation procedure of black-start, building a simulation model based on PSCAD/EMTDC platform. The simulation results verify the effectiveness and operability of the black-start strategy.
Key words: microgrid; black-start; serial restoration
