Grid Voltage Synchronization for Distributed Generation Systems Under Grid Fault Conditions [PDF]
IEEE Transactions on Industry Applications, 2015 The actual grid code requirements for the grid connection of distributed generation systems, mainly wind and photovoltaic (PV) systems, are becoming very demanding. The transmission system operators (TSOs) are especially concerned about the low-voltage-ride-through requirements.

The missing complexity in seismically imaged normal faults: What are the implications for geometry and production response? [PDF]
, 2015 The impact of geometric uncertainty on across-fault flow behaviour at the scale of individual intra-reservoir faults is investigated in this study. A high resolution digital elevation model (DEM) of a faulted outcrop is used to construct an outcrop-scale

A New Fast Peak Current Controller for Transient Voltage Faults for Power Converters [PDF]
, 2015 Power converters are the basic unit for the transient voltage fault ride through capability for most renewable distributed generators (DGs). When a transient fault happens, the grid voltage will drop suddenly and probably will also suffer a phase-jump ...
