| Abstract: |
| With an aim to improve the transient stability of a DFIG wind farm penetrated multimachine power system (MPN), an
adaptive fractional integral terminal sliding mode power control (AFITSMPC) strategy has been proposed for
the unified power flow controller (UPFC), which is compensating the MPN. The proposed AFITSMPC controls
the dq- axis series injected voltage, which controls the admittance model (AM) of the UPFC. As a result the
power output of the DFIG stabilizes which helps in maintaining the equilibrium between the electrical and
mechanical power of the nearby generators. Subsequently the rotor angular deviation of the respective generators
gets recovered, which significantly stabilizes the MPN. The proposed AFITSMPC for the admittance model of the UPFC
has been validated in a DFIG wind farm penetrated 2 area 4 machine power system in the MATLAB environment. The
robustness and efficacy of the proposed control strategy of the UPFC, in contrast to the conventional PI control is
vindicated under a number of intrinsic operating conditions, and the results analyzed are satisfactory. |
