Item Coordinación TSO-DSO para el aprovechamiento de flexibilidad en la red de distribución: Proyecto Smartnet(2019-01-29) Madina, Carlos; Jimeno, Joseba; Gómez-Arriola, Inés; Pardo, M.; Rossi, Marco; Migliavacca, Gianluigi; Kuusela, Pirkko; Tecnalia Research & Innovation; POWER SYSTEMSLa descarbonización de los sistemas eléctricos está dificultando la operación de los mismos, en particular en lo que se refiere a la operación de las redes de transporte y distribución. En este contexto, es fundamental una mayor coordinación y cooperación entre los operadores de ambas redes a fin de garantizar la estabilidad del sistema. El proyecto SmartNet ha definido varias alternativas de coordinación entre el TSO y el DSO para el aprovechamiento de recursos conectados a la red de distribución y con capacidad de aportar flexibilidad. Posteriormente, se ha desarrollado un entorno de simulación para evaluar el impacto de las distintas alternativas en un escenario plausible a 2030 en Italia, Dinamarca y España. Cada una de las opciones de coordinación llevará aparejados una serie de costes (especialmente, ligados a los sistemas TICs), pero también aportará distintos beneficios al sistema, por lo que, mediante un análisis coste-beneficio, se puede comparar la bondad de cada una de ellas e identificar las más prometedoras en cada uno de los países objeto de estudio. Con el fin de demostrar la viabilidad tecnológica de las soluciones propuestas, así como para identificar las barreras operativas de las mismas, se han desplegado tres pilotos de demostración, uno en cada país de los anteriormente indicados. La presente comunicación presenta los principales desarrollos y las conclusiones más importantes de este proyecto.Item Cost-Benefit Analysis of TSO-DSO coordination to operate flexibility markets(2019-06) Madina, Carlos; Riaño, Sandra; Gómez-Arriola, Inés; Kuusela, Pirkko; Aghaie, Hamid; Jimeno, Joseba; Ruiz, Nerea; Rossi, Marco; Tecnalia Research & Innovation; POWER SYSTEMS; SISTEMAS FOTOVOLTAICOSThis paper presents the outcome of the cost-benefit analysis (CBA) for the different alternatives defined in the project SmartNet for the coordination between transmission system operators (TSOs) and distribution system operators (DSOs). The CBA compares five coordination schemes in three countries (Italy, Denmark and Spain) on the basis of several economic indicators. On top of them, it also calculates some non-economic indicators to enrich the analysis. The main results for the Italian and the Spanish cases are presented in this paper.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 Scenario Analysis(Springer, Cham, 2019-10-25) Rossi, Marco; Merino, Julia; Madina, Carlos; Turienzo, Elena; Svendsen, Harald; Kuusela, Pirkko; Koponen, Pekka; Tecnalia Research & Innovation; POWER SYSTEMS; ADAPTACIÓN AL CAMBIO CLIMÁTICOThe performance of TSO-DSO coordination schemes depends on the characteristics of the electricity systems in which regulation reserves can be provided by both transmission and distribution resources. In order to investigate the main aspects influencing TSO-DSO interactions, three detailed electricity scenarios (related to the expected 2030 evolution of Denmark, Italy and Spain) are defined. In particular, these scenarios are designed by assuming various distribution network conditions, determining different volumes of flexibility requested by the DSO in order to carry out local services. Then, the structure of a simulation platform, aimed at testing TSO-DSO coordination schemes, is proposed. It is based on three main blocks, integrating actual market clearing, bidding and dispatching algorithms, together with a simulator for the network and all the physical power resources. Finally, the simulation results are processed by means of a cost-benefit analysis which identified the market architectures providing the highest economic benefits to the system and the main factors that influence the profitability of one TSO-DSO coordination scheme among the others.
