A Fault Tolerant Control Strategy for Three-Level T-Type Inverter in LVRT/HVRT Operation
Applied Power Electronics ConferenceThree-level T-type inverter (3LT2I) has been widely applied in photovoltaic (PV) system. When the grid fault occurs, the low-voltage ride-through (LVRT) and high-voltage ride-through (HVRT) capabilities of 3LT2I are the key to increase the system ...

LVRT capability evaluation of variable-flux PMSG based WECS
2017 IEEE Transportation Electrification Conference (ITEC-India), 2017Exponential increase in installed capacity of Wind energy conversion system (WECS) in recent years has led to increased penetration into power grid. Thus, Grid-codes have started demanding better low-voltage-ride-through (LVRT) capability of coming wind generators and behave pretty much like conventional synchronous generator.

Design of LVRT capability for grid connected PV system
2017 International Conference on Intelligent Computing, Instrumentation and Control Technologies (ICICICT), 2017This paper present the protective system for PV grid connected system using LVRT capability. We know that increasing capacity of PV systems in the grid, the grid-connected PV systems may get negative impacts on the grid in case of a disturbance. In this condition, a strategy of LVRT is given to protect the system.

Active Power Curtailment in PV Array Under LVRT Condition
2021Under LVRT, GCPV inverters aid the grid by injecting reactive power according to the grid standards whenever there is a short-term dip in the grid voltage. To ensure that the inverter output currents are limited during this period, inverter power capacity is continuously updated.
