Technical Requirements for Grid Connection, BESS, IBR, Grid FormingAbstract
This article explores the technical requirements for connecting Battery Energy Storage Systems (BESS) to the Brazilian transmission grid, focusing on ONS Technical Note DPL 0111/2025. It analyzes the fundamental distinction between grid-following and grid-forming inverters, the latter being a central requirement of the new regulation. The document provides a comparative analysis between ONS guidelines and international standards, such as IEEE Std 2800-2022, and the functional specifications of the NERC White Paper. The analysis highlights the adherence of Brazilian regulation to global best practices in performance criteria, such as the ability to withstand voltage and frequency variations and dynamic response capability, contextualizing the Brazilian regulation within the global scenario of inverter-based energy resource integration.
