Mechanism and Control Analysis of Synchronous Frequency Resonance in Distributed Power Generation System Connected to Grid

Energy Science &Engineering, EarlyView.
Small‐signal modeling reveals that insufficient system damping positions conjugate poles near the imaginary axis, fundamentally explaining the SFR mechanism. A virtual resistance control is consequently proposed to damp the resonance and effectively suppress SFR, which is validated through Hardware‐in‐the‐Loop experiments.

Placement optimization of Multi-Type fault current limiters based on genetic algorithm

Global Energy Interconnection, 2021
The fault current limiter (FCL) is an effective measure for improving system stability and suppressing short-circuit fault current. Because of space and economic costs, the optimum placement of FCLs is vital in industrial applications. In this study, two

Analysis of the fault current limiting requirement and design of the bridge‐type FCL in the multi‐terminal DC grid

IET Power Electronics, 2018
In the multi‐terminal flexible dc grid, it is important for the healthy network to ride through the dc fault. The converters should operate continuously after dc faults, staying unblocked. But the existing selective protection and isolation method may fail to react swiftly enough, because the propagation speed of the dc fault current is extremely fast.
