Inverter-Based Generation Integration Protection Challenges: Real-life Experiences

Abstract

This paper shares the real-life engineering expe-riences and the relay protection challenges when integrating inverter-based generation into the transmission grid. This article covers the relay impact study, the proposed protection scheme design, and the protection scheme implementation. The relay impact study reveals the impacts of transmission network sparsity and inverter-based generation on traditional protective relaying. The article concludes by describing the two years of post-implementation performance.
