RT24 LATAM | IBR Insertion and Digitalization as Challenges to the Power Grid's Operations

This presentation from ONS (Operador Nacional do Sistema Elétrico) focuses on the evolution of the Brazilian electrical system and its impact on protection systems, particularly in the context of network digitalization and the integration of Inverter-Based Resources (IBR). It covers key topics such as the digitalization of substations within the National Interconnected System (SIN), challenges faced during this transition, and the importance of communication networks and monitoring systems for grid protection. Additionally, it explores the effects of increased IBR penetration on transmission line protection and system-wide protections, highlighting real-world occurrences and the need for robust monitoring and configuration protocols. The presentation concludes with insights from recent workshops and a look at the future of power generation capacity between 2024 and 2028.
