Abstract: A fault on the load side of an independent microgrid will lead to an imbalance of power supply and demand in the fault area and a voltage drop. The traditional reactive compensation method cannot effectively solve the above problems in the microgrid with a high feeder impedance to inductance ratio. This paper proposes a control strategy with differential power-flow compensating based on micro-source feeder impedance. This approach uses micro-source redundant power to compensate the power flow required in the fault area by increasing the active power output, thereby improving the power balance in the fault area and suppressing the voltage drop. The power flow compensation coefficient is calculated based on the difference of each micro-source feeder impedance and the reference value of power flow compensation is dynamically adjusted according to the power required in the fault area to optimize the distribution of fault power flow and reduce feeder losses. Finally, the effectiveness of the proposed control strategy is verified by simulation and experiment.
