Abstract:

The increased penetration of wind power by doubly fed induction generator (DFIG) in power system results in higher frequency excursion and increased rate of change of frequency in the event of generation loss or increased load demand. This paper presents the added feature of frequency regulation capability of the DFIG by incorporating an extra frequency control support function, tested on an interconnected two-area restructured power system. Frequency control support function responding proportionally to the frequency deviation is proposed to take out the kinetic energy of the wind turbine for improving the frequency response of the system. The presence of Thyristor controlled phase shifter (TCPS) in series with the tie-line near one area and Superconducting Magnetic Energy Storage (SMES) at the terminal of the other area in conjunction with dynamic active power support from the DFIG results in optimal transient performance for PoolCo transactions. Integral gains of AGC loop and parameters of TCPS and SMES are optimized through craziness based particle swarm optimization (CRPSO) in order to have optimal transient responses of area frequencies and tie-line power deviation.
