摘要：The present invention discloses a secondary control method and apparatus of

parallel inverters in a micro grid, comprising: generating frequency and amplitude offundamental voltage in the voltage instruction of inverter by droop control according tooutput voltage and output current of inverter to obtain a fundamental voltageinstruction value; extracting voltage values and current values of a first and second ACsignals from output voltage and output current of inverter, generating frequencyinstruction values of the first and second AC signals by droop control to obtain voltageinstruction values of the first and second AC signals; regulating the output voltage ofinverter according to the voltage instruction value of the first AC signal, the voltageinstruction value of the second AC signal and the fundamental voltage instruction value.
