Item Achievements, experiences, and lessons learned from the European research infrastructure ERIGrid related to the validation of power and energy systems(2020-11-09) Strasser, T. I.; de Jong, E. C. W.; Sosnina, M.; Rodriguez-Seco, J. E.; Kotsampopoulos, P.; Babazadeh, D.; Mäki, K.; Bhandia, R.; Brandl, R.; Sandroni, C.; Heussen, K.; Coffele, F.; POWER SYSTEMSPower system operation is of vital importance and must be developed far beyond today’s practice to meet future needs. Almost all European countries are facing an abrupt and very important increase of renewables with intrinsically varying yields which are difficult to predict. In addition, an increase of new types of electric loads and a reduction of traditional production from bulk generation can be observed as well. Hence, the level of complexity of system operation steadily increases. Because of these developments, the traditional power system is being transformed into a smart grid. Previous and ongoing research has tended to focus on how specific aspects of smart grids can be developed and validated, but until now there exists no integrated approach for analysing and evaluating complex smart grid configurations. To tackle these research and development needs, a pan-European research infrastructure is realized in the ERIGrid project that supports the technology development as well as the roll-out of smart grid technologies and solutions. This paper provides an overview of the main results of ERIGrid which have been achieved during the last four years. Also, experiences and lessons learned are discussed and an outlook to future research needs is provided. © 2020, CIGRE - Reprint from www.cigre.org with kind permission.Item Development and Initial testing of a Virtual Laboratory for the Build-up and Testing of Microgrid Management Algorithms(2022-09) Fernández, G.; Menéndez, A.; Meneses, P.; Zubiria, A.; García, A.; Díez, F.; Jimeno, J.; Rodríguez-Seco, J.E.; Cortés, F.; POWER SYSTEMS; Tecnalia Research & InnovationIn a bid of facilitating the increasing penetration of intermittent and random renewable energies, microgrids along with their management algorithms are becoming crucial assets. To prove their effectiveness, these algorithms need to be tested in real environments and/or laboratories, which can be very difficult in many cases, especially at the initial development stages. To solve this issue, this article proposes the use of a laboratory digital twin, i.e., a virtual laboratory with a behaviour that is similar to that of real installations, aimed at facilitating the development, testing and debugging of microgrids management algorithms. The proposed solution is demonstrated to be safe and complete when it comes to test these algorithms.Item Economic Impact of Distribution Grid Operation Scenarios for the Integration of Electric Vehicles(2014-12-03) Madina, Carlos; Zabala, Eduardo; Rodríguez-Sánchez, Raúl; Turienzo, Elena; Lopez, Jose Antonio; Tecnalia Research & InnovationElectric Vehicles (EVs) will become an important part of the transport system in Europe and can thus create a number of benefits in term of oil dependence reduction, air quality improvement and trade balance enhancement. However, they can also become a burden for distribution system operator (DSOs) if they charge in an uncontrolled way. In addition, the increasing deployment of renewable energy sources (RES) and other distributed energy resources (DER) are making the distribution grid planning more complicated than in the past, when consumers were considered to be passive elements and grid was dimensioned to meet peak demand. PlanGridEV project proposes new planning procedures, which take into account the possibility to manage consumers’ electricity demand, including the charging process of EVs, both to better integrate DER and to more efficiently plan the investments in the distribution grid. The planning rules will be validated by carrying out four test beds, which will serve as an input for assessing the economic performance of four scenarios, representing four theoretical alternatives for distribution grid planning. Different services that EVs can provide to DSOs and other actors in the e-mobility ecosystem will be analysed in each scenario. Then, a grid planning tool will be developed to help DSOs consider EVs and demand and other demand response (DR) capabilities when planning distribution grid extension.Item ICT architectures for TSO-DSO coordination and data exchange: a European perspective: A European Perspective(2023-03-01) Perez, Nestor Rodriguez; Domingo, Javier Matanza; Lopez, Gregorio Lopez; Avila, Jose Pablo Chaves; Bosco, Ferdinando; Croce, Vincenzo; Kukk, Kalle; Uslar, Mathias; Madina, Carlos; Santos-Mugica, Maider; Tecnalia Research & Innovation; POWER SYSTEMSThe coordination between system operators is a key element for the decarbonization of the power system. Over the past few years, many EU-funded research projects have addressed the challenges of Transmission System Operators (TSO) and Distribution System Operators (DSO) coordination by implementing different data exchange architectures. This paper presents a review of the ICT architectures implemented for the main coordination schemes demonstrated in such projects. The main used technologies are analyzed, considering the type of data exchanged and the communication link. Finally, the paper presents the different gaps and challenges on TSO-DSO coordination related to ICT architectures that must still be faced, paying especial attention to the expected contribution of the EU-funded OneNet project on this topic. IEEEItem 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 Moving towards for Active Role for Smart Grid Users: Study about the perception of smart grids among domestic consumers in Spain (UPGRID project) / Avanzando hacia el rol activo de los usuarios de las smart grids: estudio sobre la percepción de las redes eléctricas inteligentes entre los consumidores domésticos en España (proyecto UPGRID)(Taylor & Francis, 2020) Herranz-Pascual, Karmele; Garcia-Quincoces, Eduardo; Diez-Gaspon, Itxasne; Bachiller-Prieto, RaúlIntegrating the perspective of smart grid users is the next challenge to be tackled in order to deploy fully the broad technical development of this new generation of electrical grids and improve the efficacy thereof. This is the conclusion reached by the social research developed within the framework of the European UPGRID project. This paper presents the main findings of the Spanish demonstration, working with domestic electricity consumers. The results indicate that these consumers know little about their contract and consumption of electricity, with regard to smart grids. In spite of this, there is some evidence that there is willingness among these consumers to make a change in their energy use towards more environmentally responsible behaviours, a tendency that needs to be developed so that consumers play an active role, which is essential in order to deliver optimal energy supply through smart grids. However, the results must be taken with a degree of caution, since, in spite of the major drive for recruitment, the sample was small and the experimental mortality between phases was high, so the research presented is exploratory in nature.
