摘要：In the low voltage microgrid multi inverters parallel system, the sudden change of load will lead to voltage fluctuation in the microgrid, and the fast reactive power support capability of the inverter is a necessary way to maintain voltage stability. By introducing resistance capacitance virtual complex impedance into inverter output current feedback, a fast reactive power support RC inverter inverter and its parallel power allocation method are proposed in this paper. The equivalent output impedance of the inverter is designed into resistive and capacitive, can be realized in the micro grid support fast reactive power public connection point, so as to keep the system voltage stability, and can inhibit the resonant inverter output impedance and the impedance between, to further reduce the voltage distortion. The effectiveness of the control method is verified by simulation and experiment.
