Controlled Islanding to Prevent Cascade Outages Using Constrained Spectral k-Embedded Clustering Conference Paper uri icon

abstract

  • © 2016 Power Systems Computation Conference. Controlled islanding scheme is frequently considered as the final solution to retain power system operation under cascading event outages which can lead to a major blackout. The islanding scheme can improve the power system transient stability by preserving stable areas from further outages as well as reducing the complexity and overall time required for restoration process. In this paper a constrained spectral k-embedded clustering method is defined to determine an islanding scheme with minimal active power flow disruption, while addressing generator's coherency problem. The proposed spectral clustering method uses k-medoids algorithm which is more accurate and computationally efficient than conventional k-means algorithm. The proposed scheme is tested using the IEEE 9-, IEEE39- and IEEE 118-bus test systems. Simulation results show effectiveness of the proposed methodology in creation of stable islands and prevention of system blackouts.
