Background
This project involved the development and integration of a 35 MW Battery Energy Storage System (BESS) into the Vietnam utility grid. Electric Power Engineers played a pivotal role in preparing steady state and dynamic models for the BESS, utilizing PSS/E version 33.
Challenge
The project encountered challenges in ensuring seamless integration into the Vietnam utility grid. Key challenges included fine-tuning the dynamic model to meet the specific criteria of the Vietnam interconnection, addressing observed network response issues, and achieving compliance with rigorous testing standards.

Approach
EPE navigated the challenges of integrating a 35 MW BESS into the Vietnam utility grid with a targeted solution. Beginning with the development of steady state and dynamic models in PSS/E version 33, EPE subjected the models to rigorous testing, including fault and voltage ride-through tests. Subsequent fine-tuning of the dynamic model ensured alignment with specific criteria for seamless integration into the Vietnam interconnection.
