Terzija, Vladimir (University of Manchester) Date 2017 Abstract Intentional controlled islanding aims to split the power system into self-sustainable islands after a severe disturbance, but prior the uncontrolled network separation. Given its nature (i.e. last resort for blackout prevention), this emergency control technique must be adopted as quickly as possible. This paper proposes a computationally efficient method based on graph reduction and spectral clustering. The paper contributes by describing important details of the graph reduction process in the context of controlled islanding and by the formalisation of this process. Furthermore, it demonstrates how to adopt embedded graphs to enhance the Multiway Spectral Clustering graph partitioning. Finally, it is shown how to explicitly incorporate important cannot-link constrains between coherent generator groups into the islanding problem. The proposed method is detailed using the IEEE 39-bus test case. To evaluate the algorithm performance, the method is applied to realistically-sized PEGASE test networks Subject wide-area protection and controlControlled islandingemergency controlspectral clustering To reference this document use: http://resolver.tudelft.nl/uuid:c6a56f2b-db15-485d-a22d-72bf0bb88f14 DOI https://doi.org/10.1049/cp.2016.1101 Publisher IET ISBN 978-1-78561-406-4 Source Proceedings - Mediterranean Conference on Power Generation, Transmission, Distribution and Energy Conversion (MedPower 2016) Event MedPower 2016, 2016-11-06 → 2016-11-09, Belgrade, Serbia Bibliographical note Accepted Author Manuscript Part of collection Institutional Repository Document type conference paper Rights © 2017 I.
