Abstract

This article rethinks the meaning, analysis, evaluation, and enhancement of system strength in power electronics (PE)-dominated power systems. It highlights why existing metrics intended for conventional power systems may fail to fully capture the voltage and frequency performance in PE-dominated power systems, underscoring the need for novel multidimensional strength metrics. We explore how emerging technologies [e.g., grid-forming (GFM) converters] contribute to enhancing system strength, and we highlight ongoing engineering practices worldwide aimed at strengthening power systems.
