Island microgrid delay immune reactive power distribution control method based on consistency algorithm

The invention discloses an island microgrid delay immune reactive power distribution control method based on a consistency algorithm. The method comprises the following steps: step S1, an adaptive virtual impedance module based on a multi-agent consistency algorithm is established to realize automatic adjustment of the virtual impedance of the microgrid under the condition of line impedance mismatch; S2, establishing an equivalent quadratic frequency and amplitude control without communication line which can be immune delayed, so as to eliminate the frequency and amplitude deviation caused bythe primary control; S3, sending the voltage frequency and amplitude information obtained by the equivalent quadratic control in S2 into the primary control, including the active power-Frequency, Reactive-Voltage sag control and voltage-current double closed-loop control are used to ensure the stable operation of the microgrid. The reactive power distribution control method has the beneficial effect that accurate power distribution of a plurality of converters can be realized. The voltage amplitude and frequency of multiple DG cells can be stabilized even under complex operating conditions without low-frequency communication lines, which eliminates the influence of communication delay and improves the stability and reliability of island micro-grid system under complex load conditions.
