b'cired2021.orgSESSION 1: NETWORK COMPONENTSSession 1 deals with all aspects related to the components used in the electricity distribution networks: cables, overhead lines, primary and secondary substations, transformers, switchgear plus their control, protection and monitoring systems, new active power electronics devices. It covers topics related to the life cycle optimisation of assets from design through installation, operation and maintenance, monitoring and diagnosis, to end of life management, including new techniques such as Big Data and Artificial Intelligence. The session also covers environmental aspects including eco-design and life cycle analysis, standardisation, ergonomics and safety. It aims to provide an overview of the state-of-the-art in component design and proposals for future components, including the ones needed for smartgrids, e-mobility, smartcities and microgrids. This session is an opportunity for Distribution System Operators (DSOs) and manufacturers to share their objectives.COMPONENTS FOR SMART DISTRIBUTION GRIDS COMPONENTS FOR LARGE CITIES DISTRIBUTION NETWORKSComponents incorporating local data acquisition, intelligent information generation and communicationCompact substationscapability Modular components for fast installation and Smart secondary substations extensibilityComponents and sensors for voltage control andHigh reliability solutionspower flow management Short circuit current mitigationCommunication components and infrastructures Components with increased power transfer Power electronics based grid components capabilitiesComponents for DC networks and AC/DC hybridComponents for large scale underground cablingnetworksComponents for the integration of distributedCOMPONENTS FOR RURAL AREASgenerationStorage devices Components for more resilient networks in case of Components for e-mobility high impact-low probability eventsInnovative solutions for maintenance and life COMPONENTS RELIABILITY, DIAGNOSIS ANDextension of overhead linesMAINTENANCE STRATEGY Components and solutions for the disconnection and reconnection of microgridsCondition assessment, ageing models, lifetime assessment TOWARDS GREEN COMPONENTSDiagnostics of network componentsOnline monitoring of distribution system assets,Eco-designincluding underground cables Life-cycle analysisLife extension, upgradeability, reparability Use of bio-sourced and recycled materialsUse of new solutions like digital tools, big data,Reduction of lossesartificial intelligence, drones for diagnostics andManagement of hazardous substancesmaintenance Limitation of visual and noise impactReliability and lifetime assessment of smart components and their integration in existing systems INNOVATION IN DESIGN OF COMPONENTS Impact of climate change on network componentsModellingTestingNew materialsErgonomics and usabilityEvolution of standardsFunctional specificationsSafety aspects03'
