The hybrid microgrid can make full use of the distributed generation to supplement the large power grid, but different power sources need to be coordinated before supplying more stable power. This study proposed an improved coordinated control strategy for the heterogeneous power in the hybrid microgrid. In this strategy, the reference power of the gas turbine was calculated by the predictive algorithm instead of the traditional reference power calculation method. Then, the simulation experiment was carried out. The results show that the micro gas turbine would provide the power when the photovoltaic output power was insufficient to bear the local load due to the decrease of light intensity, and the gas turbine under the improved control strategy was faster; the distribution network bus caused by the sudden change of illumination had smaller voltage fluctuation and shorter duration under the improved coordinated control strategy; the fifth and seventh harmonics generated by the voltage fluctuation were smaller under the improved strategy.
