A Model for Assessing the Degree of Digitalization in Electric Power Networks

The increasing integration of digital technologies
into electric power networks has transformed traditional grids into complex cyber-physical systems. Yet, the level of digital maturity across operators remains uneven, lacking a unified assessment framework. This paper proposes a structured model for evaluating the degree of digitalization in power grids, integrating technological, organizational, dimensions. The model introduces six core domains, technological infrastructure, data and analytics, operational processes, cybersecurity,
organizational culture, and distributed energy
integration, each evaluated across four maturity levels.
A weighted scoring system is used to compute a digitalization Score Index (DSI), allowing quantitative comparison and benchmarking. The proposed model is tested
through a case study involving a regional grid operator, demonstrating its capability to identify gaps and guide digital transformation strategies. Results show that such an approach enhances transparency, supports investment prioritization, and aligns network modernization with the
principles of smart grid development.
