Improving Low Voltage Ride-through Capabilities for Grid Connected Wind Turbine Generator [PDF]

, 2014
Low Voltage Ride-Through (LVRT) is one of the most dominant grid connection requirements to be met by Wind Energy Conversion Systems (WECS). In presence of grid voltage dips, a mismatch is produced between the generated active power and the active power ...

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

Energy Science &Engineering, Volume 14, Issue 4, Page 2263-2276, April 2026.
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.

Comparison of Fuzzy Logic and PID Control in H‐Bridge Inverter: Performance Analysis and Response Optimization

Engineering Reports, Volume 8, Issue 2, February 2026.
Under identical conditions, we benchmark PID against Fuzzy‐Logic control for a single‐phase H‐bridge inverter. FLC achieves faster rise/settling with lower THD and better disturbance rejection than tuned PID while requiring explicit rule design—offering a reproducible baseline and deployment guidance for power‐quality‐constrained inverter applications.
