Multi-energy complementary microgrid multi-master-slave control structure and method based on micro-source and load cooperative support

The invention relates to the technical field of microgrids, in particular to a multi-energy complementary microgrid multi-master-slave control structure and method based on micro-source and load cooperative support. The structure comprises a photovoltaic system, a super capacitor, a wind driven generator, a battery, a gas turbine, a charging pile and a thermal load. All the micro-sources are provided with controllers, and each cold load and each heat load are also provided with controllers. When the demand is greater than the supply limit, a heat supply network converts heat energy back to electric energy, the heat supply network and the micro-source jointly provide energy for the load through a microgrid bus, the charging pile transmits the electric energy from an AC bus of the microgridto the electric vehicle battery in a bidirectional mode through bidirectional AC-DC, idle energy is fully utilized, and the output power pressure of the micro-source is reduced. And a virtual droop control strategy is adopted
