INTRODUCTION
As global climate change and energy scarcity become increasingly prominent, it is important
that cities and stakeholders proactively address energy challenges to achieve the Sustainable
Development Goals. According to the IEC White Paper Coping with the Energy Challenge –
The IEC's role from 2010 to 2030, cities are facing the following major energy challenges:
stabilizing climate impact from fossil fuel use; meeting the energy demands of a growing urban
population; bringing electricity to citizens without access; ensuring stable and secure energy
access for all cities.
Cities are very complex "system of systems", including power grid (energy), industry, buildings,
transport, water, waste and other domains, each of which plays an important role. Various
domains play an important role in coping with urban energy challenges. On the one hand, not
only is it important for the power grid domain to be transformed, but also for industry, buildings,
transport and other domains to take proactive measures. Therefore, it is essential for
stakeholders in different domains to reach a consensus on energy challenges (including but not
limited to the intension, solutions, visions, etc.), which is conducive to improving the pertinency,
systematization and effectiveness of the city's response to energy challenges. On the other
hand, from the perspective of urban governance, it is not the most effective for each domain to
cope with energy challenges independently, and the comprehensive governance capacity of
cities to cope with energy challenges can be significantly improved through cross-domain
collaboration, interoperability and integration.
Semantic interoperability is proposed by the IEC White Paper Semantic Interoperability:
challenges in the digital transformation age. Research on semantic interoperability is being
carried out or planned in the future in the domains of city, power grid (energy), industry,
buildings, transport, etc. For example, in the domain of city, IEC SRD 63476-1 provides a gap
analysis of smart city ontology; in the domain of power grid (energy), IEC SRD 63417:–
provides guidance and planning for the development of smart energy ontologies. Domain-based
ontologies have been developed for semantic interoperability in a specific domain, but there is
a lack of cross-domain semantic interoperability research. IEC SRD 63417:– includes the
following recommendation: "Start a joint work with IEC SyC Smart Cities and IEC SyC Smart
Energy on cross domain ontologies".
From the perspective of urban governance, focusing on cross-domain semantic interoperability
and at the same time considering the diversity of technology application in rural and remote
areas, this document builds a concept system for energy challenges in smart cities, covering
core concepts such as intension, stakeholders, solutions and visions of energy challenges. As
semantic interoperability research is being carried out or planned in power grid (energy),
industry, buildings, transport and other domains, SyC Smart Cities will not be involved in
semantic interoperability within these domains. The concept system of this document contains
the core concepts of the city domain and the core concepts of cross-domain. The core concepts
relevant to energy challenges in other domains, such as power grid (energy), industry, buildings,
transport, etc., are developed for semantic interoperability within each domain and fall outside
the scope of this document. The purpose of this document includes, but is not limited to:
– fostering the coordination of perspectives on energy challenges among stakeholders in
different domains of city, and helping stakeholders identify the intension, solutions, visions,
etc. of energy challenges;
– providing a basic framework for semantic coherence and standardization of energy
challenges in different domains of city, and promoting cross-domain collaboration,
interoperability and integration;
– helping relevant standards development organizations (SDOs) identify gaps in concepts and
standards related to energy challenges in smart cities.
___________
Under preparation. Stage at the time of publication: IEC SRD CD 63417:2023.

This document provides a basic framework for cities to adopt top-down, bottom up and
federated planning and design, engineering construction, management and operation, standard
setting and other measures to effectively respond to energy challenges. This document
promotes the collaboration, integration and sustainable development of global smart cities.

4 General
4.1 A system of systems view
There are different economic models and levels of development in different countries. Even
within the same country, there are significant differences in the level of urbanization in different
regions. In consequence, the content of energy challenge is not exactly the same. Although the
specifics of energy challenges are not identical, it is important to identify common energy
challenges and find solutions accordingly. This document analyses energy challenges in smart
city from a system of systems view, as shown in Figure 1, which integrates social system, digital
system and physical system of a city to cope with energy challenge.

SOURCE: Figure 1 of IEC SRD 63235:2021, modified by adding energy challenge concerns.
Figure 1 – A system of systems view of energy challenges in smart cities

The social system, digital system and physical system work together as a complementary whole
in responding to the concerns and interests of different stakeholders. In vertical dimension, it
is made up of many energy challenges in smart city referring to IEC White Paper "Coping with
the Energy Challenge – The IEC's role from 2010 to 2030", such as climate change, energy
scarcity, electricity accessibility, energy stability and security, and so on. Taking system of
systems view enables the total capability of a city to be enhanced in a way that none of the
constituent systems can accomplish on its own.
The physical system provides an application framework that promotes the energy connection
of infrastructure in energy network, industry, building, transport and other domains in smart city,
and supports the energy interconnection and interaction among these domains in physical layer.
The digital system provides an ICT framework that achieves integration of energy network,
industry, building, transport and other domains in information and communication layer, and
turns isolated domains into horizontal integration of services using data from different domains,
which is key to achieving interoperability.
The social system provides a governance framework that coordinates arrangements of energy
challenge relevant strategies, policies, decisions, accountabilities, management measures, etc.
to reflect multiple stakeholders' concerns in social layer.
4.2 Methodology framework
The methodology framework for concept system building of energy challenges in smart cities is
a specific application of IEC SRD 63235. The methodology framework refers to a system of
systems way of thinking that supports multi-dimensional, multi-domain and multi-layer, life-cycle
and use-case analysis approaches to be used together as a complementary whole, as shown
in Figure 2.
SOURCE: Figure 2 of IEC SRD 63235:2021, modified by adding energy challenge concerns.

of energy challenge in smart city
5 Principles for concept system building
5.1 Concept system building steps
Concept system building involves a series of steps, as shown in Figure 3.

– 12 – IEC SRD 63520:2024 © IEC 2024
The concept system building steps include:
– selecting the concept field, which is "energy challenges in smart cities" (as shown in
Clause 4);
– extracting characteristics according to the components of the concept "energy challenges
in smart cities", and extracting concepts from these characteristics (as shown in 6.2);
NOTE Considering that the components which are given by IEC, ISO, ITU and other SDOs can be incomplete
or not widely applicable, it is crucial to extract supplementary concepts through the extension of "energy
challenges in smart cities".
– extracting concepts according to the extension of "energy challenges in smart cities" (as
shown in 6.3);
– identifying core concepts by relevance assessment (as shown in Clause 7);
– determining the relations and positions of these core concepts within the concept system
(as shown in Clause 8);
– visualizing the resulting concept system by means of a concept model (as shown in
Clause 8).
Figure 3 – Concept system building steps
5.2 Concept relation
Concept system describes concepts and their relations. Different concepts can be connected
through different types of concept relations. The following relations are used to develop the
concept system of energy challenges in smart cities:
a) hierarchical relation:
1) generic relation;
2) partitive relation;
b) associative relation.
In this document, Unified Modelling Language (UML)-based concept models are drawn in
accordance with ISO 24156-1. The UML-based concept model of generic relation, partitive
relation, and associative relation is shown in Figure 4, Figure 5, and Figure 6.

Figure 4 – UML-based concept model to represent generic relation

Figure 5 – UML-based concept model to represent partitive relation

Figure 6 – UML-based concept model to represent associative relation
6 Extract concepts
6.1 General
Characteristics were extracted from the components of the concept "energy challenges in smart
cities" by taking into account the smart city and the stakeholders. Then, from the city
perspectives, concepts were extracted from these characteristics. Considering that the
components of the concept energy challenges in smart cities, which is given by IEC, ISO, ITU
and other SDOs, can be incomplete or not widely applicable, it is essential to extract
supplementary concepts through the extension of "energy challenges in smart cities".
NOTE The characteristics that make up a concept can themselves be concepts.
6.2 Extracting concepts from the components
IEC and ISO offer different perspectives and understanding as shown in Table 1, though an
agreed definition for the energy challenge in smart cities given by IEC, ISO, ITU and other
SDOs remains to be agreed. The IEC's role from 2010 to 2030 outlines what are the energy
challenges. ISO addresses how these energy challenges have occurred and can be resolved.
The characteristics were extracted through the analysis of the components of the concepts,
"energy challenge" and "smart city". Then the concepts related to "energy challenges in smart
cities" were extracted through the analysis of these characteristics from the city perspectives.

"Energy challenges in smart cities" can be categorized into five dimensions: smart city vision,
stakeholder, solution, energy challenge and smart city system, as shown in Figure 7. This
conceptual framework deepens understanding by extending the scope and grouping systems
of systems to understand the complex relationships between them in balancing energy solutions
with energy availability and environmental protection within a complex smart city ecosystem.
Figure 7 has terms extracted from current relevant standards to analyse potential solutions to
this complex issue and opportunities that can be applied to a concept system building
framework (see 8.1 and 8.3).

6.3 Extracting concepts from the extension
It is important that concepts extracted from the extension of "energy challenges in smart cities"
satisfy the following principles:
– relevancy: highly relevant to smart city for addressing energy challenge;
– accuracy: it is important that concepts are accurate, clear and neutral;
– readability: the meaning is understandable without reference;
– usefulness: using and applying frequently in relevant deliverables;
– reliability: the concepts have authoritative sources or are recommended and agreed upon
by experts from relevant domains.
This document extracted concepts from the extension of "energy challenges in smart cities",
based on above principles and the category in Figure 7. The definitions of some relevant
extension are presented in Annex A for reference. Since there are many concepts extracted
from the extension, and the objects of these concepts are not at the same level, this document
further clustered these concepts, as shown in Table 2.
