A nonlinear coordinated approach to enhance the transient stability of wind energy-based power systems

Abstract

This paper proposes a novel framework that enables the simultaneous coordination of the controllers of doubly fed induction generators &#x0028 DFIGs &#x0029 and synchronous generators &#x0028 SGs &#x0029 . The proposed coordination approach is based on the zero dynamics method aims at enhancing the transient stability of multi-machine power systems under a wide range of operating conditions. The proposed approach was implemented to the IEEE 39-bus power systems. Transient stability margin measured in terms of critical clearing time along with eigenvalue analysis and time domain simulations were considered in the performance assessment. The obtained results were also compared to those achieved using a conventional power system stabilizer &#x002F power oscillation &#x0028 PSS &#x002F POD &#x0029 technique and the interconnection and damping assignment passivity-based controller &#x0028 IDA-PBC &#x0029 . The performance analysis confirmed the ability of the proposed approach to enhance damping and improve system &#x02BC s transient stability margin under a wide range of operating conditions.
