Item Added value services for EV charging management(IEEE, 2013-11) Rodríguez-Sánchez, Raúl; Vidal, Narcís; Zabala, Eduardo; Tecnalia Research & InnovationThe deployment of Electrical Vehicles (EV) is not taking place at the expected rate. Consumers’ tendency to value losses higher than gains works against electric vehicles when comparing them to traditional solutions. In this context, added value services may support business models with additional incomes, business differentiation or appealing mobility concepts. In the frame of the Green eMotion FP7 project, added value services will be proposed and their implementation in backend systems studied, in order to permit a widespread and sustainable deployment of EVs. Services and functionalities are delimited by business models defining the overall stakeholder relationship framework. Therefore, the latter will have direct influence, not only at economical level but also in technical aspects of the implementation of added value services. EV services are classified in two main groups: those provided by the EVs to the network and those provided by service providers to end-users. EVs characteristics make them especially suitable for service oriented business, while ICT solutions appear as key enablers of new sustainable mobility concepts. It is very important to decide which services and how these services need to be implemented to allow a wide range of business models to be applied. Interoperability is another essential aspect when dealing with EVs, since all systems involved in service provision should be able to communicate with each other. This will allow EV users to have transparent and efficient driving experiences, together with lower cost solutions. New advances in communication standards definition and in interoperability assessment (COTEVOS FP7 EU project) are currently going on and will tackle this challenge.Item Assessment of ICT-based Architectures for the integration of EVs in smart grids(2015-12) Rodríguez-Sánchez, Raúl; Madina, Carlos; Zabala, Eduardo; Tecnalia Research & Innovation; POWER SYSTEMSThe involvement of Information and Communication Technology (ICTs) systems in the evolution of distribution networks towards smart grid approaches is critical. The use of ICTs in the electrical system is already a fact, mainly in transmission but also at energy distribution level. It is expected that this dependency will increase in the future and, among other functionalities, it will help integrate distributed energy resources (DER), including electric vehicles (EVs), into network operation. Both remote communications and automated actions will be a characteristic of smart grids design, permitting higher levels of control and visibility in distribution networks. In general, smart grid features and processes in the fields of distribution automation, advanced metering, DER integration and customer empowering will condition the availability of services. DER system involvement in network operation processes is one of the main tools for flexibility enhancement in smart grids and the principal scope of this study. The services that could most suitably be provided by EVs to the network have been analysed through use case descriptions, involving: frequency regulation, load balancing, voltage regulation/reactive power provision, peak shaving, load profile flattening and renewable energy system (RES) integration. As result of the study, general ICT system requirements, including a network architecture, are proposed for the provision of advanced network services by EVs and other demand resources in smart grid environments.Item Economic assessment of strategies to deploy publicly accessible charging infrastructure(mdpi, 2015-12) Madina, Carlos; Barlag, Heike; Coppola, Giovanni; Gómez-Arriola, Inés; Rodríguez-Sánchez, Raúl; Zabala, Eduardo; Tecnalia Research & Innovation; POWER SYSTEMSFrom the end user perspective, the main barriers for widespread electric vehicle (EV) adoption are high purchase cost and range anxiety, both regarding battery capacity and availability of accessible EV charging infrastructure. Governments and public bodies in general are taking steps towards overcoming these barriers by, among others, setting up regulatory requirements regarding standardisation, customer information and recommending objectives of publicly accessible charging infrastructure. However, the economic performance of publicly accessible charging infrastructure is unknown and any deployment plan should be backed up by a rigorous cost-benefit analysis, to check the efficiency of the plan in economic terms. This paper presents the results of the economic assessment performed within the FP7 EU-funded Green eMotion project, where relevant conclusions for helping industry strategic approach and decision makers have been taken.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 & Innovation; POWER SYSTEMSElectric 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 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 The Innovative FlexPlan Grid-Planning Methodology: How Storage and Flexible Resources Could Help in De-Bottlenecking the European System: How storage and flexible resources could help in de-bottlenecking the european system†(2021-02-23) Migliavacca, Gianluigi; Rossi, Marco; Siface, Dario; Marzoli, Matteo; Ergun, Hakan; Rodríguez-Sánchez, Raúl; Hanot, Maxime; Leclerq, Guillaume; Amaro, Nuno; Egorov, Aleksandr; Gabrielski, Jawana; Matthes, Björn; Morch, Andrei; Tecnalia Research & InnovationThe FlexPlan Horizon2020 project aims at establishing a new grid-planning methodology which considers the opportunity to introduce new storage and flexibility resources in electricity transmission and distribution grids as an alternative to building new grid elements, in accordance with the intentions of the Clean Energy for all Europeans regulatory package of the European Commission. FlexPlan creates a new innovative grid-planning tool whose ambition is to go beyond the state of the art of planning methodologies by including the following innovative features: assessment of the best planning strategy by analysing in one shot a high number of candidate expansion options provided by a pre-processor tool, simultaneous mid- and long-term planning assessment over three grid years (2030, 2040, 2050), incorporation of a full range of cost–benefit analysis criteria into the target function, integrated transmission distribution planning, embedded environmental analysis (air quality, carbon footprint, landscape constraints), probabilistic contingency methodologies in replacement of the traditional N-1 criterion, application of numerical decomposition techniques to reduce calculation efforts and analysis of variability of yearly renewable energy sources (RES) and load time series through a Monte Carlo process. Six regional cases covering nearly the whole European continent are developed in order to cast a view on grid planning in Europe till 2050. FlexPlan will end up formulating guidelines for regulators and planning offices of system operators by indicating to what extent system flexibility can contribute to reducing overall system costs (operational + investment) yet maintaining current system security levels and which regulatory provisions could foster such process. This paper provides a complete description of the modelling features of the planning tool and pre-processor and provides the first results of their application in small-scale scenarios
