Item Electra IRP voltage control strategy for enhancing power system stability in future grid architectures(2017-10-01) Merino, Julia; Rodríguez-Seco, J.E.; García-Villalba, Íñigo; Temiz, Armağan; Caerts, Chris; Schwalbe, Roman; Strasser, Thomas I.; Temiz, Armaǧan; Tecnalia Research & Innovation; POWER SYSTEMSThis study is intended to show the future voltage control strategy designed in the framework of the ELECTRA Integrated Research Programme (IRP) project for the web-of-cells (WoC) concept. This scheme, called post-primary voltage control, aims to keep the node voltages at any time within the bands defined by the regulations and to minimise the power losses in the system by calculating the optimal voltage set-points for the different nodes. The reactive power will mainly be used to restore the voltages but also active power could be delivered in some cells depending on their voltage levels. Different operating modes of the voltage control will be discussed taking both planning and the real-time operation phases into account. The application of the voltage control strategy to one test grid considered as representative of the WoC structure will also be shown in this study.Item A Survey on honeypots, honeynets and their applications on smart grid(Institute of Electrical and Electronics Engineers Inc., 2019-06) Dalamagkas, Christos; Sarigiannidis, Panagiotis; Ioannidis, Dimosthenis; Iturbe, Eider; Nikolis, Odysseas; Ramos, Francisco; Rios, Erkuden; Sarigiannidis, Antonios; Tzovaras, Dimitrios; Jacquenet, Christian; De Turck, Filip; Chemouil, Prosper; Esposito, Flavio; Festor, Olivier; Cerroni, Walter; Secci, Stefano; CIBERSEC&DLTPower grid is a major part of modern Critical Infrastructure (CIN). The rapid evolution of Information and Communication Technologies (ICT) enables traditional power grids to encompass advanced technologies that allow them to monitor their state, increase their reliability, save costs and provide ICT services to end customers, thus converting them into smart grids. However, smart grid is exposed to several security threats, as hackers might try to exploit vulnerabilities of the industrial infrastructure and cause disruption to national electricity system with severe consequences to citizens and commerce. This paper investigates and compares honey-x technologies that could be applied to smart grid in order to distract intruders, obtain attack strategies, protect the real infrastructure and form forensic evidence to be used in court.
