A Protection Method for Inverter-based Microgrid Using Current-only Polarity Comparison
Journal of Modern Power Systems and Clean Energy, 2020 The design of an effective protection system for inverter-based microgrids is a complicated engineering challenge. This is due to the fact that inverters have limited fault current capabilities, and that the conventional overcurrent protection is not ...

Climate Resilience and Sustainability, Volume 5, Issue 2, December 2026.This paper presents a framework for Multiple Resilience Dividends (MRD) that proposes shift climate change adaptation from a narrow risk‐focused perspective to a broader, multi‐objective systems approach. By recognizing the diverse range of benefits that adaptation measures can provide, practitioners can go beyond merely avoiding losses.
