Item Aggregation of thermostatically controlled loads for flexibility markets(2019-06) Jimeno, Joseba; Ruiz, Nerea; Madina, Carlos; POWER SYSTEMSThis paper presents a tool for an aggregator of thermostatically controlled loads (TCLs) to optimally combine their flexibilities into a few representative bids to be submitted to flexibility markets. The tool employs a “bottom-up” approach based on physical end-use load models, being the individual flexibility of each individual TCL simulated with a second-order thermal model describing the dynamics of the house. The approach is based on a direct load control (DLC) of thermostat temperature set-point by the aggregator. End-users receive an economic compensation in exchange for the loss of comfort. The applicability of the proposed model is demonstrated in a simulation case study based on an actual power system in Spain.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 Exploiting flexibility of radio base stations in local DSO markets for congestion management with shared balancing responsibility between TSO and DSO(2018) Madina, Carlos; Jimeno, Joseba; Merino, J.; Pardo, M.; Marroquin, M.; Estrade, E.; POWER SYSTEMSElectric power systems are facing major challenges as fossil fuel generation is replaced by renewable generation, which is often characterised by variable behaviour. This increases the need for resources to be used to guarantee voltage and frequency stability and to ensure power quality. At the same time, an increasing number of flexible demand and storage systems are being located at distribution level. All these resources can potentially provide network services if they are aggregated effectively. To achieve this, however, the roles of the diverse network stakeholders –transmission systems operators (TSOs), distribution systems operators (DSOs) and aggregators– should be reshaped. Together, the way realtime electricity markets are organised must also be adapted to reflect the new operating environment. The project SmartNet (http://smartnet-project.eu/) compares five TSO-DSO coordination schemes and different real-time market architectures with the aim of finding out which one could deliver the best compromise between costs and benefits for the system. An ad-hoc-developed platform is used to carry out simulations on three benchmark countries –Italy, Denmark and Spain– whose results are used to perform a cost-benefit analysis. This analysis compares the benefits drawn by the system with the ICT costs needed to implement each coordination scheme. In parallel, three demonstration projects (pilots) are deployed for testing specific technological solutions to enable monitoring, control and participation in ancillary services provision from flexible entities located in distribution networks. This paper summarises the achievements of the Spanish pilot during the first two years of operation. The pilot includes technical and economic aspects, under the “Shared balancing responsibility model”, to demonstrate the feasibility of using urban, distributed radio base stations to provide ancillary services for the DSO through demand side management. In this model, the balancing responsibility is divided between the TSO and the DSO, so that each of them must ensure a predefined schedule in the common border. With that aim, the DSO organises a local market to respect the schedule agreed with the TSO, while the TSO has no access to resources connected to the distribution grid. Commercial market parties such as aggregators become flexibility providers of aggregated distributed energy resources at the local market and the DSO allocates flexibility among them in a competitive manner. Additionally, the local market is used also by the DSO for managing the congestions in its own grid.Item ICT Requirements in a Smart Grid Environment(Springer, Cham, 2019-10-25) Horsmanheimo, Seppo; Tuomimäki, Lotta; Rodríguez-Sánchez, Raúl; Andrén, Filip Pröstl; Andersen, Claus Amtrup; Tecnalia Research & InnovationEnergy systems are moving towards more flexible and distributed structures as the share of distributed energy resources gets bigger. New resources connected to the distribution grid offer ancillary services for congestion management and balancing including, e.g. frequency control, aFRR/mFRR, and voltage control. The new TSO-DSO coordination schemes presented in Chap. 2 are studied in this chapter from ICT’s perspective. This chapter introduces a conceptual reference model to help assess where new communication technologies are needed. The second section introduces potential technologies that could be applied. Our focus is more on wireless technologies to ensure flexibility, cost-efficiency, and scalability in large geographically distributed systems. We also present different types of service architectures to manage, secure and orchestrate the increasing number of services created by the new market models. The provision of ancillary services from distribution networks involves the coordination and close interaction between different actors and systems. In the last section, we present a process of capturing ICT requirements for energy systems. The process utilises the Smart Grid Architecture Model (SGAM) that presents a structured approach for modelling the Smart Grid architecture.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.Item Technologies and Protocols: The Experience of the Three SmartNet Pilots: The experience of the three smartnet pilots(Springer, 2019-10-25) Madina, Carlos; Jimeno, Joseba; Ortolano, Luca; Palleschi, Margherita; Ebrahimy, Razgar; Madsen, Henrik; Pardo, Miguel; Corchero, Cristina; POWER SYSTEMSThe deployment of technological pilots is of paramount importance for testing and demonstrating the technical feasibility of the concepts described in this book for two main reasons. On the one hand, there are few real-life experiences in the application of these concepts, as TSO-DSO coordination is a relatively new topic. On the other hand, there may be some implementation difficulties which cannot be anticipated by the scenario analysis and CBA. Whenever possible, more than one pilot should be deployed, so that each of them can focus on different parts of the TSO-DSO coordination value chain. In that sense, it is important to demonstrate different potential TSO-DSO coordination schemes, so that issues arising from each of them can be identified. Moreover, it is also important to demonstrate different types of DER, so that their flexibilities can be better assessed and the advantages and disadvantages for real-life implementation can be properly identified and addressed. As a third complementarity aspect, having different technological pilots allows for focusing on different parts of the value chain, so that one of them may take the vision of the TSO or DSO, while another one can focus on the needs of the aggregator or DER owners.Item TSO-DSO coordination to acquire services from distribution grids: Simulations, cost-benefit analysis and regulatory conclusions from the SmartNet project: Simulations, cost-benefit analysis and regulatory conclusions from the SmartNet project(2020-12) Rossi, Marco; Migliavacca, Gianluigi; Viganò, Giacomo; Siface, Dario; Madina, Carlos; Gomez, Inés; Kockar, Ivana; Morch, Andrei; POWER SYSTEMSThe continuously growing distributed generation and the business potential for demand response are gradually enabling significant provision of flexibility and reserve towards distribution networks. For this reason, transmission and distribution system operators need to coordinate their operation in order to develop efficient market arrangements that can help utilize all the resources capable of providing ancillary services. SmartNet project investigated the potential interaction schemes between network operators, together with the possible new services devoted to the optimal distribution grid management. This paper summarizes the main challenges in simulating complex electricity systems and flexibility markets for three European countries (Italy, Denmark and Spain) in 2030 scenarios. The simulation results are then analyzed using cost-benefit analysis and regulatory conclusions are deduced.Item Use of radio base stations to provide ancillary services to the DSO through local flexibility markets(2019-06) Pardo, Miguel; Duarte, M.; Madina, Carlos; Marroquin, M.; Estrade, E.; POWER SYSTEMSThe changes in the energy sector require an appropriate coordination between transmission systems operators (TSOs), distribution systems operators (DSOs) and aggregators. The project SmartNet aims at defining and comparing different TSO-DSO coordination schemes, by implementing dedicated analyses in Italy, Denmark and Spain. This paper describes the pilot project implemented in Spain and presents its main outcomes.
