Energy Systems Digitalization: Challenges and Opportunities for a Sustainable Future

Dear Colleagues,

The evolution of the smart grid concept from the end of the 20th century to the current digitalization of the electricity system reflects a significant change in its scope and sophistication. While the initial focus was on grid automation to improve efficiency and reliability, the emphasis was on remote monitoring and control of the electricity infrastructure. However, communication was mainly one-way, from utilities to consumers.

The current approach involves a comprehensive transformation of the electricity system, with digitalization at all levels, from generation to consumption. The goal is a bidirectional, flexible, and adaptable grid capable of massive integration of renewable energy and intelligent demand management. The consumer becomes an active player (the prosumer) with the ability to generate, store, and manage their own energy.

This Special Issue aims to address the current landscape by seeking original innovations in the application of technologies such as the following:

• Internet of Things (IoT): for pervasive device and sensing connectivity.
• Artificial Intelligence (AI) and Data Analytics: for optimized operation and maintenance of the grid.
• Blockchain: for managing secure energy transactions and creating decentralized markets.
• Machine-to-machine (M2M) communications: for seamless interaction between devices.
• Cyber-physical system (CPS) architectures: for integrated control of the physical and digital network.
• Cloud Computing: for scalable data storage and processing.
