Abstract The multi-energy complementary microgrid demonstration power plant of Tibet Couqin county including photovoltaic, wind farm and hydropower was comprehensively investigated in this paper. Firstly, virtual synchronous generator (VSG) control strategy for the flexible configuration of microgrid was proposed. Besides, the component of the multi-energy complementary microgrid and its control were discussed. Also, the principle and mathmatical model of the VSG were described. Additionally, the control function of VSG in the photovoltaic station standalone and parallel with hydropower station operation modes, as well as during the seamless transfer between two modes was analyzed. Finally, operational results of the microgrid were utilized to confirm the feasibility and effectiveness of the proposed control strategies. The experimental results demonstrate that the presented control strategy can not only perform good active and reactive sharing features, but also can provide significant inertia and damping for the microgrid to improve its power quality and stability. Furthermore, seamless transfer between different operation modes can be also ensured to satisfy the requirements of microgrid.

Key words： Multi-energy complementary microgrid virtual synchronous generator photovoltaic station hydropower station seamless transfer
