Item Economic Implications of DSO-TSO Coordination Schemes at a System Level and for Market Actors in case of Flexibility or Traditional Grid-based Solution(IEEE, 2022-10) Madina, Carlos; Gonzalez-Garrido, Amaia; Gomez-Arriola, Ines; Tecnalia Research & Innovation; POWER SYSTEMSThis paper proposes a methodology to evaluate the economic implication of the use of flexibility to solve both joint DSO-TSO and local DSO-specific congestion management needs. The presented methodology enables evaluating the economic implications at a system level and per market actor according to the selected DSO-TSO coordination scheme and given flexibility needs. Firstly, several DSO-TSO coordination schemes are presented to solve joint needs, in which market access to flexible resources at the distribution grid is enabled to a greater or lesser extent. Secondly, the use of flexibility is compared to traditional grid solutions (i.e., grid reinforcement, temporary commissioning services) to enable the DSO to make cost-efficient grid decisions in the short and medium term. Finally, the economic impact on flexible service providers at the distribution level is carefully presented. This methodology seeks to support energy policies and other regulatory decisions.Item Flexibility markets to procure system services. CoordiNet project(IEEE, 2020-10-13) Madina, Carlos; Gomez-Arriola, Ines; Santos-Mugica, Maider; Jimeno, Joseba; Kessels, Kris; Trakas, Dimitris; Pablo Chaves, Jose; Ruwaida, Yvonne; Tecnalia Research & Innovation; POWER SYSTEMSThe efficiency and reliability of electricity systems depend, among other aspects, on an efficient collaboration between the different market participants, which require updating the roles of all agents involved. The CoordiNet project, co-funded by the EU, intends to demonstrate how TSOs and DSOs can act in a coordinated manner, to purchase and activate system services, promote the cooperation of all actors and eliminate barriers for the active participation of DERs in the market. The results of the project will help to design scalable tools and methodologies for system operators and third parties to safely connect, manage and coordinate flexibility providers. This paper describes the developments in CoordiNet to ensure the interoperability of the different markets and platforms developed by TSOs and DSOs across Europe.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 Large-scale demonstration of TSO–DSO coordination: the CoordiNet Spanish approach: the CoordiNet Spanish approach(2020) Utrilla, F. David Martín; Davi-Arderius, Daniel; Martínez, Alberto Gil; Chaves-Ávila, José Pablo; Arriola, Inés Gómez; POWER SYSTEMSThe necessary energy transition to decarbonise power systems is leading to increasingly important challenges for the operation of power systems. On the one hand, the intermittent nature of renewable generation requires system operators to procure system services in larger volumes than in the past. On the other hand, the growing penetration of medium- and small-scale, flexible demand and storage systems in distribution networks might result in congestions or voltage problems in this grid level, but these resources could potentially offer system services, if they are aggregated effectively and there is appropriate coordination between transmission system operators (TSOs), distribution system operators (DSOs) and aggregators. Therefore, an interesting topic to be analysed is whether distributed energy resources can replace traditional generation in the provision of system services, how this replacement will affect the system operators' roles and how to improve the coordination between TSOs and DSOs. The CoordiNet project aims at demonstrating, through different TSO–DSO coordination schemes, options for providing system services with flexible resources located at different voltage levels. This study shows the Spanish demonstrators, in which REE (TSO) and the two largest DSOs, i.e. e-distribución and i-DE participate, as well as IIT Comillas and Tecnalia, among several European partners.Item Markets and platforms to coordinate the procurement of system services from large-scale and small-scale assets connected to the electricity network(2020) Madina, Carlos; Santos-Mugica, Maider; Gómez-Arriola, Inés; Jimeno, Joseba; POWER SYSTEMSThe efficiency and the reliability of the electricity system depend on an efficient collaboration between the different market participants. New challenges for the power sector, which require updating the roles of all agents involved, have emerged due to the growing importance of renewable energy sources, the advance of distributed generation, the development of self-consumption, the storage of energy and the mass integration of the electric vehicles. In this context, the safe and efficient functioning of the electricity system is linked to exploiting the untapped flexibility potential in both generation and demand. Therefore, the coordination of distribution system operators (DSOs) and transmission system operators (TSOs) in the procurement of system services provided by units located in both distribution and transmission grids become one of the current challenges.Item Optimised TSO-DSO Coordination to Integrate Renewables in Flexibility Markets(IEEE, 2019-09) Madina, Carlos; Kuusela, Pirkko; Rossi, Marco; Aghaie, Hamid; Gomez-Arriola, Ines; Riaño, Sandra; POWER SYSTEMS; SISTEMAS FOTOVOLTAICOSThe necessary energy transition to decarbonize power systems is leading to increasingly important challenges for the operation of power systems. On the one hand, the intermittent nature of renewable generation requires system operators to procure ancillary services in larger volumes than in the past. On the other, the growing penetration of medium- and small-scale, flexible demand and storage systems in distribution networks could potentially offer network services, if they are aggregated effectively and there is an appropriate coordination between transmission system operators (TSOs), distribution system operators (DSOs) and aggregators. Therefore, an important topic to be analysed is whether distributed energy resources (DER) can replace traditional generation in the provision of ancillary services (AS), how this replacement will affect the system operators’ roles and how to improve the coordination between TSOs and DSOs. This paper shows the results of the cost-benefit analysis (CBA) performed within the project SmartNet to assess the advantages or disadvantages of different TSO-DSO coordination schemes, as well as the follow-up activities to be carried out in the project CoordiNet.Item Real-Time Flexibility Market Participation of Thermostatically Controlled Loads(IEEE, 2022) Jimeno, Joseba; Ruiz, Nerea; Madina, Carlos; Gonzalez-Garrido, Amaia; Tecnalia Research & Innovation; POWER SYSTEMSThe objective of this paper is to demonstrate the feasibility of using the aggregated flexibility of thermostatically controlled loads (TCLs) to provide balancing and congestion management services to system operators through the participation in a real-time flexibility market. To this aim, a TCL aggregation model that employs a bottom-up approach based on physical end-use load models has been developed. A direct load control (DLC) scheme is considered, where the control variable is the thermostat temperature setpoint. This temperature can be manipulated between the upper and lower limits set by end-users, who receive an economic compensation in exchange for the loss of comfort. As output a set of flexibility bids to be sent to the market are obtained. To demonstrate the applicability of the proposed aggregation model and estimate the overall flexibility potential from TCLs, a large-scale case study, based on a future power system in Spain has been considered.Item Recursos flexibles para la operación de las redes de distribución y transporte: proyecto CoordiNet(2020-01) Madina, Carlos; Gómez-Arriola, Inés; Chaves, Jose Pablo; Pardo, Miguel; Martin, David; Junco, Paula; Tecnalia Research & Innovation; POWER SYSTEMSLa transición energética requiere de una adecuada coordinación entre el TSO y el DSO para el desarrollo y adquisición de nuevos servicios de flexibilidad en todos los niveles de tensión, a fin de integrar de forma segura y eficiente un volumen creciente de generación renovable en las redes de distribución y transporte. En este sentido, el proyecto CoordiNet está desarrollando diez proyectos de demostración en España, Grecia y Suecia, donde se analizarán diferentes alternativas para la compra de los nuevos productos y servicios de flexibilidad definidos en el proyecto. La presente comunicación presenta en detalle los demostradores españoles, liderados por Endesa y en los que participan Iberdrola y Red Eléctrica de España, además de varias empresas, centros de investigación y universidades.Item A Straightforward Methodology to Obtain the Power Coefficients Matrices for Unbalanced Distribution Networks to be Used in Flexibility Markets(IEEE, 2022) Cortés Borray, Andrés Felipe; Santos-Mugica, Maider; Gonzalez-Garrido, Amaia; Martin, David; Ojeda, Carlos; Borray, Andres Felipe Cortes; Tecnalia Research & Innovation; POWER SYSTEMSThe objective of the paper is to address the congestion problem in a specific distribution line by means of sensitivity coefficients seeking an intelligent a ctivation of t he available flexibility, based not only on economic a spects but also on the efficient use of flexibility. This paper proposes a straightforward methodology to obtain the sensitivity coefficient matrices for the unbalanced distribution networks, employing the perturb-and-observe (P & O) approach to assure an efficient usage of flexible resources. This means that a small change in the active power value of a particular flexibility provider, either load or generator, is applied to evaluate the power variation, therefore the loading variation, in every line of the system. The paper shows how these coefficients can be implemented in at heoretical energy market by the market operators by validating its application in an unbalanced network case and then compared with a real balanced distribution network. The simulations have been carried out in DIgSILENT PowerFactory through its API in Python.Item TSO-DSO-Customer coordination for purchasing flexibility system services: Challenges and lessons learned from a demonstration in Sweden(2022-07-07) Ruwaida, Yvonne; Chaves-Avila, Jose Pablo; Etherden, Nicholas; Gomez-Arriola, Ines; Gurses-Tran, Gonca; Kessels, Kris; Madina, Carlos; Sanjab, Anibal; Santos-Mugica, Maider; Trakas, Dimitris N.; Troncia, Matteo; POWER SYSTEMSThis paper presents a real-word implementation of a TSO-DSO-customer coordination framework for the use of flexibility to support system operation. First, we describe the general requirements for TSO-DSO-customer coordination, including potential coordination schemes, actors and roles and the required architecture. Then, we particularise those general requirements for a real-world demonstration in Sweden, aiming to avoid congestions in the grid during the high-demand winter season. In the light of current congestion management rules and existing markets in Sweden, we describe an integration path to newly defined flexibility markets in support of new tools that we developed for this application. The results show that the use of flexibility can reduce the congestion costs while enhancing the secure operation of the system. Additionally, we discuss challenges and lessons learned from the demonstration, including the importance of the engagement between stakeholders, the role of availability remuneration, and the paramount importance of defining appropriate technical requirements and market timings.
