Technical scope


Fast evolving cities will drive the transformation of the energy systems, with 60% of humanity expected to live as city-dwellers in 2030. Cities will use two-thirds of the world’s energy and produce a similar proportion of global carbon emissions. This places cities at the heart of the climate change discussion and sustainability. City authorities, planners and utilities are investigating how to develop the electrical infrastructure in a way that supports economic growth and high quality-of-life while also integrating more renewable energy sources (RES) than ever before, and radically reducing cities’ impact on the environment. The answer is in the smart city paradigm that leverages data and digital connectivity to rethink the city planning and management for the long-term sustainability and wellbeing of cities. To scale up rapidly and substantially, most cities will need to increase their focus on decarbonizing buildings, factories with electrification solutions, and smart mobility. In buildings, rooftop solar PV and solar water heating are easy to install and offer significant economic gains. In transport, electric mobility, when powered by renewable sources, reduces air pollution and is increasingly cost competitive. Electric mobility and RES will be the main drivers for power distribution development. As renewable energy technologies spread, buildings and transport will become increasingly interconnected with the power system as well as the electricity, heat, water and waste management sectors. Thus cities need to plan for integrated urban energy systems, using expertise from multiple sectors from urban planning to waste management. In this context, the digitalization – the increasing interaction and convergence between the digital and physical worlds – is crucial for enabling the fast, resilient and sustainable development of cities. Digitalization with the three main areas on Data, Analytics, and Connectivity will inevitably play a key role in the transition towards smart cities.

Theme 1 : Planning and development of smart cities

Digitalization enables the convergence of several services in such a way that can completely reshape the urban texture of large cities. Data analytics techniques, such as machine learning and artificial intelligence, can produce the data for detailed planning studies that consider different energy and services by exploiting the real time information on the consumption of energy in its different forms, on the traffic flows, on people habits, on city economy, on geography and orography, etc. The integrated planning of services and networks will be crucial to make the fast growing of large cities in different time horizons possible.

Preferred topics for papers are :

  • Planning the development and the upgrade of power distribution
  • Planning the RES integration in fast growing cities
  • Impact of E-mobility on distribution planning
  • Integrated urban planning (power, gas, thermal, water, communication, transportation and waste)
  • Integrated planning of digital infrastructures (e.g. integrated data centers)
  • Inclusion of Cyber security in distribution planning and development
  • Artificial intelligence, machine learning, expert systems for planning smart city distribution networks
  • Smart buildings, smart districts, smart factories, microgrids
  • Business models, markets and regulatory framework impact on the smart city development

Theme 2 : Equipment and components for the smart cities

Fast growing smart cities require special components and technical solutions to cope with fast increasing demand and to integrate high shares of renewable and widespread e-mobility by meeting high quality levels of service continuity and resiliency. Standardized, pre-built stations and sub-stations equipped with sensors and digital communications should be considered for the day-by-day development of smart cities. New digital conceived smart grid components will be the backbone of any smart city and permit the seamless fast growth of large urban areas.

Preferred topics for papers are :

  • Smart, compact and eco-friendly substations, and smart transformers
  • Pre-built power stations and substations
  • High ampacity underground cables and superconductivity cables
  • Fault current limiters (for sub-grids connections, energy demanding transport infrastructure, etc.)
  • Components for active network operations (e.g., fault location, isolation and service restoration, dynamic load Management, power flow management, power quality conditioners)
  • DC distribution and AC/DC hybrid solutions
  • AC and DC charging stations for private and public transportation
  • Distributed and centralized storage
  • Technical solutions for upgrading existing assets
  • Innovative condition monitoring

Theme 3 : Digitalization enabling new services, operation schemes and customer engagement

The digitalization of the city distribution system can enable new services and new markets for consumers, producers, and energy service providers, and impact the operation of distribution systems. Many services have the potential of postponing the need of infrastructural investments for reinforcing existing assets or building new ones, optimizing existing infrastructures associated with power distribution in a fast growing city. The digitalization enables aggregation, smart districts, and buildings, as well as the transition towards electric mobility and full electric cities (e.g. smart charging and/or V2G) that can significantly impact on the distribution system operation. The incoming Internet of Energy, with the emerging community systems operator (CSO) responsible for planning and operational control of the automated, blockchain-enabled energy community, can significantly change the distribution business. The distribution network could be used for providing security and adequacy to local energy communities, having their own local production, generation, storage and a local market. Finally, the Internet of Things (IoT) will offer plenty of data that can be used for harvesting the inherent flexibility not only of electrical prosumers and active consumers but also from the integration of other services and systems.

Preferred topics for papers are :

  • Aggregators and demand response in fast growing cities (e.g. Virtual Power Plants, flexibility mechanisms)
  • Multi energy/multi services networks and systems
  • Operation and energy management of smart districts and buildings (e.g. community systems operator, etc.)
  • Integration and operation of E-mobility in large cities, smart public lighting and distributed storage
  • Peer to peer energy transaction and local markets (blockchain)
  • Interoperable digital platforms for the integration of city services
  • Big data to improve and optimize the operation of smart distribution systems
  • Innovative operation of the distribution system (e.g., IoT integration, etc.)

Theme 4 : Reliable and Resilient Smart Power Distribution

Digitalization increases the level of reliability and resilience in smart cities and improves the quality and wellbeing of citizens, which must be in the center of the digitalization process. In this context, condition based asset management can benefit from the use of interconnected sensors and devices, artificial intelligence and machine learning for better reliability and continuity of service. The use of decision support systems helps to mitigate the impact of natural disasters or climate effects by increasing the level of awareness and enabling the fast implementation of recovery plans. Digitalization brings many benefits, but it also opens the door to increasing risks for energy security, both from natural hazards such as geomagnetic storms and from unintended cyber incidents and intentional cyber-attacks. Attacks on energy systems are likely to be particularly disruptive since power systems must operate in real-time and cannot simply install patches or updates, or shut down and reboot as in the typical response to digital failures or breaches. Cybersecurity and resilience need to be made a central part of energy research, development and deployment. Finally, the growing use of digital technologies in the energy sector raises questions about data privacy and ownership. Smart grids and demand response technologies rely on vast quantities of consumer-specific, real-time electricity usage data. Viewed from an overall systems perspective, policymakers might consider that there is a wide public interest in making aggregate data publicly available, but at the same time they must also take into account the privacy concerns of their constituents. An appropriate balance between consumers’ privacy concerns and the operational needs of utilities and new market players should be found by using appropriate data management techniques to foster demand response, customer engagements and local markets.

Preferred topics for papers are :

  • Digitalization and Asset Management
  • Decision Support Systems and Risk Awareness for Resilient Distribution Systems
  • Citizen awareness and resiliency
  • Cyber security techniques for digital power distribution
  • Cyber physical modelling and simulation for smart cities
  • Microgrids and smart districts for resiliency
