technical content

The technical content of CIRED is mainly based on the 6 sessions the main conferences address:

Session 1: Network components

Session 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 Arti cial Intelligence. The session also covers environmental aspects including eco-design and life cycle analysis, standardisation, ergonomics and safety. It aims at providing an overview of the state-of-the-art in component design and proposals for future components, including the ones needed for smart grids, e-mobility, smart cities and microgrids. This session is an opportunity for DSOs and manufacturers to share their objectives.

Session 2: Power quality and electromagnetic compatibility

Session 2 deals with power quality (PQ), with the more general concept of electromagnetic compatibility (EMC) and with related safety problems in electrical networks. Special focus is put on continuity of supply (supply interruptions, reliability) and voltage quality (voltage level, icker, unbalance, harmonics, voltage dips) as well as related measurement and analysis techniques. This session also deals with electromagnetic compatibility (mains frequency to 150 kHz), electromagnetic interferences and electric and magnetic elds issues.

Session 3: Operation, control and protection

Session 3 deals with the operation of networks, including control technology and system protection, which is a more and more challenging topic in the emerging environment of smart grids, distributed generation and e-mobility. The relevant technical and economic targets of distribution grid operators, the expectations and requirements of stakeholders as well as solution strategies of scientists and manufacturers of new products will be presented and discussed in Session 3. Both recent practical experiences and the results from current research as the basis of future developments are very welcome.

Session 4: Distributed energy resources and efficient utilisation of electricity

Session 4 deals with the challenges of adapting distribution networks to facilitate the e cient integration of low carbon, renewable and Distributed Energy Resources (DER). These include Distributed Generation (DG), energy storage, new loads (e.g. electric heating and Electric Vehicles (EVs)), active demand and aggregation of DER (e.g. Virtual Power Plants). DER integration challenges are likely to feature across all CIRED sessions so Session 4 speci cally focuses on emerging technologies and solutions, results from research, development or demonstration programmes with results from network and system integration trials being particularly valued. Session 4 papers will highlight the integration of DER within distribution networks through technical, commercial and regulatory solutions. Papers may describe developments in network management, demand side response, energy storage integration, e cient utilisation of electricity, network monitoring, telecommunications and data analytics and the role of DER in wider DSO business operations. Also within the scope of Session 4 is whole energy system optimisation (including integration across other infrastructure systems and energy vectors), e cient management of network losses and the results from the larger smart grid demonstration projects.

Session 5: Planning of power distribution systems

Session 5 deals with all aspects related to the short and long term development of high, medium and low voltage distribution networks, with reference to the changing requirements for electricity distribution including, but not limited to, smart grids and active distribution networks, electric vehicles, storage, active demand and distributed energy resources integration, present and future customer quality of supply requirements, and optimum asset utilisation techniques and strategies. There is increasing interest in strategies designed to meet the rapidly changing level of demand in both rural and urban areas, the extension of electri cation in rural areas requiring a high quality of supply, and development strategies intended to increase resiliency against low probability high risks extreme events.

Session 6: DSO customers, regulation and business models

Session 6 focuses on the evolving business environment and regulation of the DSO to support active customer’s and society’s energy transition. This includes the fast paced and disruptive developments around digitalization, collaborative economy, market based exibility services, integration of microgrids, storage & e-mobility and, not to be forgotten, cyber-security to ensure a sustainable and e cient electricity distribution infrastructure. At the same time the asset/risk management and regulation optimization is still key for the DSO. To understand impacts, strategic choices, implementation options and limitations is vital. Important sources for knowledge are results from demonstration projects and case studies that are discussed in a transparent and open environment, like in CIRED.

Moreover, CIRED also organizes a Workshop each even year on specific topics. Click here to access the list of these events.
