Research on Black start Capability of Microsources in Isolated Microgrid

Abstract:

Based on the characteristics of each microsource, the black start capability of microsources is researched and Bayesian decision method is applied to optimize the selection plan of black start primary reference source under different initial conditions. The models of microturbine, battery, solar and wind power generation are built in MATLAB/Simulink platform. By the simulation results, the black start capability of each microsource is compared and the feasibility of Bayesian decision method is validated. The results show that the microturbine and battery are good black start sources in microgrids due to their excellent capability of power output and the stability of voltage output. Photovoltaic power generation and wind power generation influenced by the outside environment are not suitable as black start sources.
