In order to improve the output gain of stadium smart microgrid under large disturbance,a power coordinated control method of stadium smart microgrid based on proportional resonance regulation is proposed.An active and reactive power coordinated dispatching model of smart microgrid for sports venues under large disturbance is established;The proportional resonance control method is used to suppress the disturbance in the process of power coordinated control of stadium smart microgrid,and the dead time and voltage drop scheduling of stadium smart microgrid under large disturbance are carried out.Through the method of switching current control mode and voltage control mode,the large disturbance proportional resonance is adjusted,and the constraint parameter model of power coordination control for stadium smart microgrid is established.Through the method of parameter optimization,the multi proportion of harmonic current loop is coordinated to realize the power coordinated control of smart microgrid in stadiums.The simulation results show that the proposed method can effectively improve the output stability and the ability of adaptive parameter optimization.The global stability control is optimally realized by fuzzy iteration,which effectively improves the output gain of the stadium smart microgrid under large disturbance.
