Ground Fault Location and Severity Estimation Method for DC/DC Converters

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
A method for detection, location and severity estimation of ground faults for DC/DC converters has been designed. The method consists in analysing the voltage signal of a grounding resistor that connects the neutral point of the system—which can be the AC neutral point of the star of the main power transformer or an artificial DC midpoint—and ground ...

Source‐Storage‐Load Coordinated Regulation Method for a Photovoltaic‐Dominated Microgrid Considering Dynamic Characteristics of Energy Storage

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
PV‐dominated microgrids face storage ageing‐induced power boundary shrinkage, which conventional fixed‐boundary strategies cannot handle. This paper proposes a multi‐time‐scale source‐storage‐load coordinated regulation method that embeds a dynamic SoC‐SoH‐SoP boundary into day‐ahead dispatch and real‐time power allocation, using flexible loads for ...
