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, so that the voltage and the frequency of the microgrid are always stabilized at the same value. Thus, the stability and the adaptability of the multi-energy complementary microgrid are improved, and the power quality of the system is improved.
