Assessment of the Inertia of Peru's National Interconnected Electric System, 2040: Regulatory Need for Synthetic Inertia

This paper assesses the declining synchronous inertia in Peru's National Interconnected Electric System (SEIN) by 2040 under high renewable penetration, demonstrating that critical frequency stability risks necessitate the regulatory implementation of synthetic inertia, a finding quantified through a newly proposed Integrated Frequency Security Index (IISF-SEIN).
