The utility model discloses a microgrid system for laboratories, which is capable of providing more theoretical bases and test bases for large-scale high-efficiency utilization of renewable energy sources and the construction of microgrids in China. The microgrid system for the laboratories comprises a dummy bus. Interconnection switches which respectively correspond to the dummy bus are connected with a dummy wind power generation system, a dummy solar power generation system, a dummy generator system, a dummy battery energy storage system, a dummy load system and a dummy power quality management system; the dummy bus is also connected with a power transmission network through the corresponding interconnection switch via a two-way watt-hour meter, therefore, the microgrid system for the laboratories is formed. A microgrid controller is connected with all the interconnection switches; control is performed by the microgrid controller by adopting one or more than one of the grid-connected operation control strategy or the isolated network operation stable control strategy or the active power regulation and reactive power optimization control strategy or the grid-connected/isolated network mode switching strategy or the multi-power supply coordination control strategy and the energy optimization control strategy, and coordination control is performed on a renewable energy source grid-connected device and a power quality management device, therefore, renewable energy source grid-connected harmonic suppression and voltage disturbance resistance can be completed.
