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 GLocalFlex, New Flexibility Solutions and Services. Cross-Pilot Overarching Business Use Cases(IEEE Computer Society, 2024) Madina, Carlos; Gonzalez-Garrido, Amaia; Gomez-Arriola, Ines; Santos-Mugica, Maider; Kuusela, Pirkko; Tamminen, Arttu; Mehnert, Stephan; POWER SYSTEMSThe GLocalFlex project aims to mobilise demand side flexibility in a replicated manner. A novel element is an auction marketplace where individual households up to industrial size consumers provide batches of flexibility to one or many procurers. In that sense, it is necessary to describe new business models and to develop, deploy, demonstrate and evaluate the newly developed flexibility solutions and services. GLocalFlex will demonstrate the interaction of the novel marketplace with six pilots across Europe. Based on the specific business use cases to be deployed by the different pilots, eight overarching business use cases, which reflect the main objectives of the business use cases proposed by the pilots, have been identified. This paper presents a description of the overarching business use cases, their relevance for the different pilots and how the use of the GLocalFlex marketplace will contribute to facilitating the provision of flexibility by small consumers.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 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.
