Integration of energy and communication systems in smart cities

What are the challenges of integrating energy and communication systems in smart cities? What is the role of the standards, especially about EMC? This is the panel's context promoted by SCENT project and Bright Cities, with the mediation provided by SCENT ESR2 - Hermes Loschi, in conjunction with ETOPIA ESR 7 - Francinei Vieira and the electrical engineer at ABB - Carlos Eduardo Bertolassi.

Initially, the needs for systems integration were widely adopted and used by telecommunication companies, especially by systems of supervision and control of traffic and switching (Fig.1) [1].

Nowadays, in smart cities, the integration concept has been used to establish conformity in the interaction between the various systems present in a city, emphasizing electrical and electronic systems [2].
A smart city has several "pillars." It stands out environments such as renewable energy generation systems, electric vehicles, manufacturing, and industry 4.0. Overall, the trends and challenges in the context of the integration of energy and communication systems can be associated as:

• General objective: 3D (decarbonization, decentralization, digitization)
• Trends: Interconnected systems (renewable energy, electric and autonomous vehicles, transport, industrial and telecom)
• Challenges: stability (variability of solar \ wind generation), multipoint monitoring (real-time measurement \ bidirectional exchange of information \ processing), interoperability between systems (EMC, and EMI).

On the other hand, the technological trends and challenges of application engineering must also be considered, highlighting:

• The exponential growth of application and the proximity of electronic and telecommunications devices and equipment in environments, such as domestic, commercial, industrial, hospital, educational, and mobile (vehicles).

Therefore, considering the technological trends are generally disruptive and the need for standardization, especially in smart cities. An example is the case of 5G [3]. It is important to discuss the role of regulatory systems and application engineering in integrating energy and communication systems.
