The capacity of different distributed generation varies depending on various factors such as itself and the environment. The application of the droop control method can effectively solve the power distribution problem between two or more distributed generations. In order to solve the problem that the traditional droop control can not be applied in resistor-inductance circuit

an improved droop control method based on the adjustable reactor is proposed. Firstly

the reason why the traditional droop control can not be applied in the resistor-inductance circuit to realize the power distribution is analyzed. The specific method of improving droop control by using the adjustable reactor is proposed. Then

a flux-controlled adjustable reactor is proposed

the expression of the output impedance is obtained

and the stability is analyzed. Finally

the MATLAB simulation model with the improved droop control method is built. The simulation results show that when the capacity ratio of two distributed generations is set to 2:1

applying the improved droop control method can change the active power ratio from 6:5 to 2:1 in steady state and shorten the reactive power stabilization time from 200 ms to 50 ms

which meets the power distribution requirements. The simulation results prove that the improved droop control method based on adjustable reactor can effectively achieve the distribution of active and reactive power.
