This paper investigates the droop control based real and reactive power load sharing with virtual inductor when the line impedance between inverter and Point of Common Coupling (PCC) is resistive partly and unequal in high-capacity systems. In this paper, the virtual inductor method apply to parallel inverter systems with the resistive and inductive line impedance. The virtual inductor method reduces coupling of the active power and reactive power due to line resistance and improves the dynamic characteristics of the droop control due to get rid of the resulting active power and reactive power due to resistance component of line impedance and improves. And the reactive power sharing error has been improved by applying the droop control after considering each line impedance voltage drop in this paper. But in the high capacity parallel system with the large output current, the reference output voltage which is the output of droop controller become lower than the rated value because of the high voltage drop due to the virtual inductance. Hence, the line impedance voltage drop has been added to the droop equation so that parallel inverters operate within the range of rated output voltage. Additionally, the virtual inductor value has been selected through the small signal modeling to analyze the stability in transient condition. Because the existing paper uses adaptive transient droop method, complex small signal equations are calculated. Also it show the MATLAB simulation about single system parameters. In this paper, adaptive transient droop method is not used and the proposed droop control method is applied. And it show the simulation about two system parameters. So this can realize the simple small signal modeling. Also it can get the virtual inductance which satisfies simultaneously stable transient droop method of two systems. This small signal method selects maximum virtual inductance in the stable region, so it improves dynamic response of the droop control and ensures stability of inverter systems. Finally, the proposed droop method has been verified through the MATLAB and PSIM simulation.
