The participation of wind farms in grid emergency control is considered necessary to ensure the safe and stable operation of power systems with high-proportion wind generation. The grid voltage can be improved through the power control of doubly fed wind farm (DFWF) under grid faults. However, existing methods provide reactive power within the allowable power range (APR) under internal constraints of doubly fed wind turbine (DFWT). The precise control of DFWF is difficult to achieve, and its power controllability is underutilised because of the different operation status of DFWTs and the coupling between the APR and the grid voltage. Accordingly, an improved control method of DFWF is proposed to improve the voltage under grid fault. The power characteristics of DFWF are analysed. APR is described under internal constraints. The feasible power range (FPR) of DFWT under coupling is investigated. The connotations of FPR and APR are analysed, based on which a novel idea of active control of DFWF power is proposed. The maximum and optimal voltage operation points of DFWT under wind speed and rotor speed restrictions are calculated. The improved voltage control strategy is proposed. The simulation shows that the proposed method can significantly improve the voltage through the precise control of DFWF power.
