Low voltage ride through (LVRT) enhancement of a two-stage grid-connected photovoltaic system based on finite-control-set model predictive control strategy

International Journal of Renewable Energy Development
Grid-connected photovoltaic (PV) systems face numerous challenges during grid faults, including fault detection, synchronization, over-current protection, fluctuations in DC-link voltage, and compliance with active and reactive power requirements.

Active islanding detection technique for inverter-based microgrids using optimized negative sequence disturbance injection

International Journal of Electrical Power & Energy Systems
Deploying grid ancillary services in distributed energy resources (DERs) can interfere with islanding detection techniques (IDTs), potentially enlarging their non-detection zone. Several active IDTs have been accordingly presented for inverter-based DERs
