The Role of Digital Twins in Substation Management and Grid Optimization

In recent years, digital twin technology has emerged as a game-changer in various industries, and the power sector is no exception. Digital twins are transforming how substations are managed by creating virtual replicas that provide insights into performance and potential issues. A digital substation is the physical interface that makes digital twin modelling of electrical assets possible.

This article explores the application of digital twin technology in substations, its benefits for predictive analytics and decision-making,...
