Item A case analysis of enabling continuous software deployment through knowledge management(2018-06) Colomo-Palacios, Ricardo; Fernandes, Eduardo; Soto-Acosta, Pedro; Larrucea, Xabier; Tecnalia Research & InnovationContinuous software engineering aims to accelerate software development by automating the whole software development process. Knowledge management is a cornerstone for continuous integration between software development and its operational deployment, which must be implemented using sound methodologies and solid tools. In this paper, the authors present and analyse a case study on the adoption of such practices by a software company. Results show that, beyond tools, knowledge management practices are the main enablers of continuous software engineering adoption and success.Item Decentralized platform economy: emerging blockchain-based decentralized platform business models(2022-09) Lage, Oscar; Saiz-Santos, María; Zarzuelo, José Manuel; CIBERSEC&DLTEmerging decentralized multisided platforms aim to create more open collaborations between participants and question currently centralized networked business models, such as Google, Amazon, Uber, or Airbnb. In this paper, a systematic analysis of the emerging decentralized platform economy is presented based on blockchain technology. The research aims to fill a gap in the literature, as there is currently no specific analyses on these emerging multisided decentralized electronic markets. Eighty-two decentralized platforms were studied. The study contributes to the literature on decentralized platform taxonomy to structure the emerging research domain of decentralized platform business models. Applying a cluster analysis, three emerging archetypes of decentralized platforms were found, referred to as hosted, federated, and shared platform models. The research contributes to a better understanding of emerging decentralized business platforms. According to the findings, two-thirds of the analyzed platforms, namely, federated and shared archetypes, do not follow traditional models. Rather, their aim is to create new business and community relationships. Furthermore, the archetype of shared platforms is the most disruptive, showing a higher level of decentralization and business model change.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 Influence of the addition of multiwall carbon nanotubes in the sintering of nanostructured yttria-stabilized tetragonal zirconia polycrystalline(2012-01) Garmendia, Nere; Sanstacruz, Isabel; Moreno, Rodrigo; Obieta, Isabel; Tecnalia Research & InnovationThe properties of yttria-stabilized tetragonal zirconia polycrystalline (YTZP) ceramics, such as low thermal conductivity, excellent biocompatibility, high fracture toughness, high strength, and low wear rates, make them suitable for many applications. To further increase these properties, the use of nanostructured materials and/or the addition of reinforcing second phases such as carbon nanotubes are being investigated. In the present work, it has been demonstrated that with the addition of zirconia partially coated multiwall carbon nanotubes to a nanostructured YTZP matrix the densification is enhanced at lower temperatures and a finer microstructure is obtained.Item Neural Network Power Flow Approach to Detect Overload and Voltage Anomalies in Low-Voltage Unbalanced Networks, Agnostic of Network Topology(IEEE Computer Society, 2024) González-Garrido, Amaia; Rivera, Jon Ander; Zaballa, Juan Florez; Rodríguez-Seco, Jose Emilio; Perea, Eugenio; POWER SYSTEMS; IA; DIGITAL ENERGYThe application of Power Flow (PF) algorithms at Low Voltage (LV) becomes essential, to ensure safe and cost-effective operation. Deterministic approaches do not appear suitable and scalable for LV networks, with a higher risk of non-convergence. The proposed Neural Network Power Flow model (NN-PF) provides accurate power loading, voltage magnitudes and angles in LV unbalanced network, based on nodal consumption and generation power, while being agnostic of the LV network model. Broader dataset is generated for training and testing purposes, including solar generation and undesired voltage events. Despite challenges posed by limited dataset size and the absence of the network topology and features, the NN-PF demonstrates robust performance and high accuracy to identify voltage anomalies and overloads in LV networks. The highest Mean Absolute Error (MAE) is 2e-4 p.u. (0.48 V), 4.6 kW active and 1.51 kVAr reactive power flow at extreme steady-state conditions (V < 0.95 p.u.).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 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.
