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 Laboratory infrastructure driven key performance indicator development using the smart grid architecture model(2017-10-01) H. Syed, Mazheruddin; Guillo-Sansano, Efren; Blair, Steven M.; Burt, Graeme M.; Strasser, Thomas I.; Brunner, Helfried; Gehrke, Oliver; Rodriguez-Seco, Jose E.; POWER SYSTEMSThis study presents a methodology for collaboratively designing laboratory experiments and developing key performance indicators for the testing and validation of novel power system control architectures in multiple laboratory environments. The contribution makes use of the smart grid architecture model as it facilitates the integration of individually developed control functions into a consolidated solution for laboratory validation and testing. The experimental results obtained across multiple laboratories can be efficiently compared, when the proposed methodology is adopted and thus the study offers means of support for improved cooperation in smart grid validation and round robin testing.Item Scenario-based approach adopted in the ELECTRA project for deriving innovative control room functionality(2017-10-01) Marinelli, Mattia; Heussen, Kai; Prostejovsky, Alexander; Bindner, Henrik W.; Catterson, Victoria M.; Merino, Julia; Tornelli, Carlo; Tecnalia Research & InnovationHere, the authors analyse the operator point of view of the Web-of-Cells concept defined in the EU project ELECTRA, by identifying operator tasks into the supervision of a highly automated power system, and the information requirements to facilitate appropriate operator situation awareness. The study outlines the methodology adopted, which is based on the cognitive work analysis framework, to provide an overview of the most interesting scenarios and to summarise the requirements analysis results. In order to derive required control room functionality, a set of relevant control room scenarios have been identified based on the Web-of-Cells control concept. The authors considered scenarios that challenge traditional control schemes, scenarios that caused major failures (i.e. blackouts), and scenarios that can be expected to appear in the future. For each scenario, information concerning network layout, triggering events, physical constraints, manually/automatic operations, operators' tasks, and relevant analytics have been analysed.
