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 ERIGrid Holistic Test Description for Validating Cyber-Physical Energy Systems(2019-07-16) Heussen, Kai; Steinbrink, Cornelius; Abdulhadi, Ibrahim F.; Nguyen, Van Hoa; Degefa, Merkebu Z.; Merino, Julia; Jensen, Tue V.; Guo, Hao; Gehrke, Oliver; Bondy, Daniel Esteban Morales; Babazadeh, Davood; Pröstl Andrén, Filip; Strasser, Thomas I.; Van Hoa, Nguyen; Tecnalia Research & InnovationSmart energy solutions aim to modify and optimise the operation of existing energy infrastructure. Such cyber-physical technology must be mature before deployment to the actual infrastructure, and competitive solutions will have to be compliant to standards still under development. Achieving this technology readiness and harmonisation requires reproducible experiments and appropriately realistic testing environments. Such testbeds for multi-domain cyber-physical experiments are complex in and of themselves. This work addresses a method for the scoping and design of experiments where both testbed and solution each require detailed expertise. This empirical work first revisited present test description approaches, developed a newdescription method for cyber-physical energy systems testing, and matured it by means of user involvement. The new Holistic Test Description (HTD) method facilitates the conception, deconstruction and reproduction of complex experimental designs in the domains of cyber-physical energy systems. This work develops the background and motivation, offers a guideline and examples to the proposed approach, and summarises experience from three years of its application.Item An integrated pan-European research infrastructure for validating smart grid systems(2018-12-01) Strasser, Thomas I.; Pröstl Andrén, F.; Widl, E.; Lauss, G.; De Jong, E. C. W.; Calin, M.; Sosnina, M.; Khavari, A.; Rodriguez, J. E.; Kotsampopoulos, P.; Blank, M.; Steinbrink, C.; Mäki, K.; Kulmala, A.; van der Meer, A.; Bhandia, R.; Brandl, R.; Arnold, G.; Sandroni, C.; Pala, D.; Morales Bondy, D. E.; Heussen, K.; Gehrke, O.; Coffele, F.; Tran, Q.-T.; Rikos, E.; Nguyen, V. H.; Orue, I.; Degefa, M. Z.; Manikas, S.; POWER SYSTEMSA driving force for the realization of a sustainable energy supply in Europe is the integration of distributed, renewable energy resources. Due to their dynamic and stochastic generation behaviour, utilities and network operators are confronted with a more complex operation of the underlying distribution grids. Additionally, due to the higher flexibility on the consumer side through partly controllable loads, ongoing changes of regulatory rules, technology developments, and the liberalization of energy markets, the system’s operation needs adaptation. Sophisticated design approaches together with proper operational concepts and intelligent automation provide the basis to turn the existing power system into an intelligent entity, a so-called smart grid. While reaping the benefits that come along with those intelligent behaviours, it is expected that the system-level testing will play a significantly larger role in the development of future solutions and technologies. Proper validation approaches, concepts, and corresponding tools are partly missing until now. This paper addresses these issues by discussing the progress in the integrated Pan-European research infrastructure project ERIGrid where proper validation methods and tools are currently being developed for validating smart grid systems and solutions.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.
