The Need for Modeling the Impact of Behind-the-Meter Generation Trip on Primary Frequency Response Through Operational Experiences in Korea Power System

This letter introduces the impact of behind-the-meter generation (BTMG) trip on primary frequency response through recent operational experience in Korea, and examines whether this impact can be appropriately modeled in power system analysis. The most influential parameter for properly modeling BTMG trip is discussed in the case studies, demonstrating that simulation-based studies can reproduce the interesting observation of instantaneous load increase (i.e., the impact of BTMG trip). The outcome of this letter highlights the necessity for modeling BTMG trip in frequency stability analysis, especially for power systems with high penetration of BTMG.
