In order to more accurately calculate the power variation of the active rural distribution networks with the doubly-fed-introduction generator after different types of faults occur, a new transient power deviation model (TPD) based on the branch flow model is proposed in this paper. The TPD model includes the inter-phase coupling factor and the dynamic interaction factor between buses. Based on the electromagnetic coupling between distribution cables and the dynamic interaction between buses, these two coefficients are used to calculate the transient power of the bus. Therefore, the TPD model offers a more intuitive representation of the active and reactive power deviations at the buses in the distribution system. Subsequently, based on the TPD model, the modified voltage-transient power control strategy (MV-TPC) is proposed. By redesigning the rotor-side converter side controller of DFIG, the impact of the faults, which cannot be repaired in a short period, on system stability is reduced. And the voltage stability at the point of common coupling of the DFIG is improved. Finally, simulations are conducted using the RTDS simulator on an IEEE 34-Buses distribution system in Arizona, USA, with the distribution DFIG to verify the effectiveness of MV-TPC in suppressing voltage fluctuations. The research results demonstrate its potential application in improving the stability of the distribution systems with wind farms.
