The invention relates to an
energy system of a micro-grid. The
energy system of the micro-grid comprises a first
bus, a second
bus and a third
bus, wherein the first bus is connected with a first bus inlet end of a
power grid through a first static switch, the second bus is connected with a second bus inlet end of the
power grid through a second static switch, loads are connected to the first bus and the second bus respectively, a
bus coupler switch is arranged between the first bus and the second bus in a connected mode, the two ends of the third bus are correspondingly connected with the first bus and the second bus of the micro-grid through a first grid-connecting switch and a second grid-connecting switch respectively, the third bus is connected with a micro-grid
energy device, the micro-grid
energy device comprises a
photovoltaic power generation module, a
wind power module, an
energy storage module, a fuel
cell module and a V2G module, a diverter switch is arranged between the
photovoltaic power generation module and the third bus in a connected mode, a diverter switch is arranged between the
wind power module and the third bus in a connected mode, a diverter switch is arranged between the
energy storage module and the third bus in a connected mode, a diverter switch is arranged between the fuel
cell module and the third bus in a connected mode, and a diverter switch is arranged between the V2G module and the third bus in a connected mode. The problems that flexibility and reliability of an
energy system of an existing micro-grid are poor, and the low-carbon purpose is not achieved are solved.
